Tutorial 2: C++ cin object of iostream.

Today's Task is that i have to teach you cin object of iostream.
Cin is an object. It is one of the members of iostream family, and iostream is a header file.

#include<iostream.h>    // header file
#include<conio.h>        //  header file

void main()                  //  main function
{                                 //  Opening brackets of main function

       clrscr();               /*  clrscr function is used to clear the screen and it is good habit for programmers to                                           use that function in the start of every program.*/
       int var;                //   Variable Declaration


       cout<< " Enter the Value of var: ";      /*  cout is use to print something in on the screen. In this                                                                                    line we simply print Enter the Value of var: on the screen. */
       cin>> var ;                           /*   In this line cin is used the functionality of cin ( Console                                                                                    Input ) is to input some value from the user and store it in the variable                                                            which is given. */
       getch();                                  /*  this function is used to get character from the user. The purpose of this function at that place is only that we want to stop the execution and see the result of the program. If you donot use that function when you run the program it may only blink and do not show any result. */

}                                 //  Closing brackets of main function

In this program I try to teach you  cin of a C++ and how a cin works. I use cout and cin in this program.
Now your task is to read this post very carefully and practice it on your on pc.
InshAllah Next I will try to teach All of you the new Functions of C++ .
