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

Tutorial 1: C++ cout object of iostream.

From Today i have start a tutorials for you.
Today's Task is that i have to teach you a basic of C++.
Cout 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
       var = 1;              //   Value Assignment
