A Simple Program That is Written in C++ Language

#include<iostream.h> 
 #include<conio.h> 
 void main() 
 { 
           clrscr(); 
           int a,b; 
           cout <<"Welcome To C++ Language "; 
           getch(); 
 } 
 

1) In This #include is the preprocessor directive that is given by the c++ language it denotes to include the header file iostream.h means to include all the functions of the input output Stream header file which contains all the input and output functions like cout and cin all these are contained in it.

2) The Second Header file is used for using the getch and clrscr() functions

3) void main()

In this void means no Returnment of any value means a void doesn’t return any value it just performs the executions of the program one by one

4) Main() : – The () braces are the symbol of a function every function has braces In this Main () function has a main Role because the Execution of all the programs are started from the Main () function This is also known as the starting point of the program It executes the Statements as they are in The Main() function and in the block means in the open curly braces { and the closed curly braces }

{

}

These are used for denoting a block of statements those are to be executed

5) Clrscr() This is the built in function that is provided by c++  for removing the Results of the Previous Program which is made by any user. So when a user will execute his Program then this will first Clear the Contents of the Screen.

6) Conio header file this function is used for clear the contents of the screen

7) getch()
