C++ How to Program, 10th Edition
Developed by Bjarne Stroustrup of Bell Laboratories in the early s, it is based on the traditional C language but with added object-oriented programming and other capabilities. This very feature and its many other capabilities also make it one of the most difficult languages to learn and handle on a large scale.
This mode is the default in GCC versions prior to 6. The committee tries hard not to break your standard conforming code. This mode is the default in GCC 6. The special needs of embedded systems programming are presented, including ROMability and predictability. While not an official part of the standard, it proposed a number of extensions to the standard library. The draft can be found here. Refer to working draft N This Technical Specification is applicable to information technology systems that can access hierarchical file systems, such as those with operating systems that conform to the POSIX 3 interface.
This Technical Specification is applicable only to vendors who wish to provide the interface it describes. The individual bytes of the source code file are mapped in implementation-defined manner to the characters of the basic source character set. In particular, OS-dependent end-of-line indicators are replaced by newline characters. The basic source character set consists of 96 characters:. Phase 2 Whenever backslash appears at the end of a line immediately followed by the newline character , both backslash and newline are deleted, combining two physical source lines into one logical source line.
This is a single-pass operation; a line ending in two backslashes followed by an empty line does not combine three lines into one. The source file is decomposed into comments, sequences of whitespace characters space, horizontal tab, new-line, vertical tab, and form-feed , and preprocessing tokens, which are the following:.
Each file introduced with the include directive goes through phases 1 through 4 , recursively. All characters in character literals and string literals are converted from the source character set to the execution character set which may be a multibyte character set such as UTF-8, as long as the 96 characters of the basic source character set listed in phase 1 have single-byte representations.
Escape sequences and universal character names in character literals and non-raw string literals are expanded and converted to the execution character set. Compilation takes place: each preprocessing token is converted to a token. The tokens are syntactically and semantically analyzed and translated as a translation unit. Each translation unit is examined to produce a list of required template instantiations, including the ones requested by explicit instantiations.
The definitions of the templates are located, and the required instantiations are performed to produce instantiation units. Translation units, instantiation units, and library components needed to satisfy external references are collected into a program image which contains information needed for execution in its execution environment.
Since they are used by the language, these keywords are not available for re-definition or overloading. There are alternative spellings for several operators and other tokens that use non-ISO characters. In all respects of the language, each alternative token behaves exactly the same as its primary token, except for its spelling the stringification operator can make the spelling visible. The two-letter alternative tokens are sometimes called digraphs :.
Identifiers Identifiers Constitution An identifier is an arbitrarily long sequence of digits, underscores, lowercase and uppercase Latin letters, and most Unicode characters.
A valid identifier must begin with a non-digit character Latin letter, underscore, or Unicode non-digit character. Identifiers are case-sensitive, and every character is significant. An identifier can be used to name objects, references, functions, enumerators, types, class members, namespaces, templates, template specializations, parameter packs, goto labels, and other entities, with the following exceptions:.
Reserved here means that the standard library headers define or declare such identifiers for their internal needs, the compiler may predefine non-standard identifiers of that kind, and that name mangling algorithm may assume that some of these identifiers are not in use.
If the programmer uses such identifiers, the behavior is undefined. C-style comments or multi-line comments , which cannot be nested. All comments are removed from the program at translation phase 3 by replacing each comment with a single whitespace character. For any other type, value is false :. The void type with an empty set of values. It is an incomplete type that cannot be completed consequently, objects of type void are disallowed.
There are no arrays of void, nor references to void. However, pointers to void and functions returning type void are permitted. Checks whether T is a void type. Provides the member constant value that is equal to true , if T is the type void , const void , volatile void , or const volatile void.
Otherwise, value is equal to false. There exist implicit conversions from nullptr to null pointer value of any pointer type and any pointer to member type. It is a distinct type that is not itself a pointer type or a pointer to member type. If T is an arithmetic type that is, an integral type or a floating-point type , provides the member constant value equal true. For any other type, value is false. The bool type is capable of holding one of the two values: true or false.
The value of sizeof bool is implementation defined and might differ from 1. Also used to inspect object representations raw memory.
Required to be large enough to represent any supported character code point 32 bits on systems that support Unicode. It has the same size, signedness, and alignment as one of the integral types, but is a distinct type. The keyword int may be omitted if any of the modifiers listed below are used.
Checks whether T is a floating-point type. Provides the member constant value which is equal to true, if T is the type float , double , long double , including any cv-qualified variants. Usually IEEE 32 bit floating point type.
Usually IEEE 64 bit floating point type. Does not necessarily map to types mandated by IEEE Usually bit x87 floating point type on x86 and x architectures.
It compares equal to the positive zero, but is meaningful in some arithmetic operations, e. Some operations on floating-point numbers are affected by and modify the state of the floating-point environment most notably, the rounding direction.
Implicit conversions are defined between real floating types and integer types. If T is a compound type that is, array, function, object pointer, function pointer, member object pointer, member function pointer, reference, class, union, or enumeration, including any cv-qualified variants , provides the member constant value equal true.
Note: Compound types are the types that are constructed from fundamental types. A reference is required to be initialized to refer to a valid object or function: see reference initialization. Reference types cannot be cv-qualified at the top level; there is no syntax for that in declaration, and if a qualification is introduced through a typedef, decltype, or template type argument, it is ignored.
References are not objects; they do not necessarily occupy storage, although the compiler may allocate storage if it is necessary to implement the desired semantics e.
Because references are not objects, there are no arrays of references, no pointers to references, and no references to references:. Lvalue references can be used to alias an existing object optionally with different cv-qualification :. Rvalue references can be used to extend the lifetimes of temporary objects note, lvalue references to const can extend the lifetimes of temporary objects too, but they are not modifiable through them :.
More importantly, when a function has both rvalue reference and lvalue reference overloads, the rvalue reference overload binds to rvalues including both prvalues and xvalues , while the lvalue reference overload binds to lvalues:.
Although references, once initialized, always refer to valid objects or functions, it is possible to create a program where the lifetime of the referred-to object ends, but the reference remains accessible dangling. Accessing such a reference is undefined behavior. A common example is a function returning a reference to an automatic variable:. If the referred-to object was destroyed e.
If T is a reference type lvalue reference or rvalue reference , provides the member constant value equal true. Checks whether T is a lvalue reference type. Provides the member constant value which is equal to true, if T is a lvalue reference type. Checks whether T is a rvalue reference type.
Provides the member constant value which is equal to true, if T is a rvalue reference type. Because of the array-to-pointer implicit conversion, pointer to the first element of an array can be initialized with an expression of array type:. Because of the derived-to-base implicit conversion for pointers, pointer to a base class can be initialized with the address of a derived class:.
If Derived is polymorphic , such pointer may be used to make virtual function calls. Comparison operators are defined for pointers to objects in some situations: two pointers that represent the same address compare equal, two null pointer values compare equal, pointers to elements of the same array compare the same as the array indexes of those elements, and pointers to non-static data members with the same member access compare in order of declaration of those members.
Many implementations also provide strict total ordering of pointers of random origin, e. Those implementations that do not e. This makes it possible to use all pointers of random origin as keys in standard associative containers such as std::set or std::map. A pointer to function can be initialized with an address of a non-member function or a static member function.
Unlike functions or references to functions, pointers to functions are objects and thus can be stored in arrays, copied, assigned, etc. A pointer to function can be used as the left-hand operand of the function call operator , this invokes the pointed-to function:.
A pointer to function may be initialized from an overload set which may include functions, function template specializations, and function templates, if only one overload matches the type of the pointer see address of an overloaded function for more detail :. Equality comparison operators are defined for pointers to functions they compare equal if pointing to the same function. Such pointer may be used as the right-hand operand of the pointer-to-member access operators operator.
Pointer to data member of an accessible unambiguous non-virtual base class can be implicitly converted to pointer to the same data member of a derived class:.
The pointed-to type of a pointer-to-member may be a pointer-to-member itself: pointers to members can be multilevel, and can be cv-qualifed differently at every level. Mixed multi-level combinations of pointers and pointers-to-members are also allowed:.
The resulting expression can be used only as the left-hand operand of a function-call operator:.

Reviews There are no reviews yet. In this book there are a lot of practice questions without solution. Object-Oriented Programming OOP is the term used to describe a programming approach based on objects and noanimalpoaching.org object-oriented paradigm allows us to organise software as a collection of objects that consist of both data and behaviour. A solution manual is the guide or answers to the end of chapter questions and activities from the textbook. A test bank is a collection of test questions tailored to the contents of an individual textbook. Book Description. For a great example of object-oriented programming in C, look at the source of POV-Ray from several years ago - version g is particularly good.

It is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features. Some of its application domains include systems software, application software, device drivers, embedded software, high-performance server and client applications, and entertainment software such as video games. The language began as enhancements to C , first adding classes, then virtual functions, operator overloading, multiple inheritance, templates, and exception handling among other features. Stroustrup began work on 'C with Classes' in The idea of creating a new language originated from Stroustrup's experience in programming for his Ph.
