C++ is an Object Oriented Language and general-purpose programming language. C++ contains object oriented concepts which has so many advantages. It is designed in terms of System Programming and Embedded system.
In 1983, “C with Classes” was renamed to “C++”, adding new features that included virtual functions, function name and operator overloading, references, constants, type-safe free-store memory allocation (new/delete), improved type checking, So, We can say that c++ is an extension of C language.
-:C++ contains following topics at TCCI:-
Introduction to C++, Basic Syntax, Object Oriented Concept, Data Types and Variables, Constants, Literals, Modifiers, Operators, Loop Controls, Decision Making, Class Structure with Object, Function, Arrays, String, Inheritance, Constructor-Destructor, Exception Handling, Files etc.
-:Structure of C++ Program:-
Headers
In any C++ program there are different headers in C++, each of which contain information that is necessary in the program. The header option is used in program which provides basic input and output services for C++ programs.
Namespaces
In any C++ program namespaces are a relatively recent addition to C++.
Main()
In any C++ program the program execution begins with the following line as the main() function is the entry point.
Return
In any C++ program the termination of the main() function is signalled by the return(0); statement. After this, the zero(0) value is returned to the calling process as program flows.
Example:-
#include <iostream>
using namespace std;
int main()
{
cout << "Happy to learn C++ language"
<< endl;
return 0;
}
Output:
Happy to learn C++ language
