    int a=10,b=10;
    if(a=b)
    cout<<"equal";
    else
    cout<<"Not Equal";

    output:
    Not equal

    Use "==" instead of "=" in if condition. 

    int a=10, b=10;
if(a==b)
  cout<<"equal";
else
  cout<<"Not Equal";

    output should be "equal"..
    can any one explain why Not equal is given as o/p here

    I think you are getting confused.

    The following program prints "equal"

    #include<iostream>
using namespace std;

int main()
{
    int a=10, b=10;
    if(a==b)
        cout<<"equal";
    else
        cout<<"Not Equal";
    return 0;
}

    In your original program, you were using = instead of ==

    The question itself is wrong, whether you use '=' or '==', you get the same output for a=10, b=10(not zero values of a &b).

    output will be 'equal' inside the if() condition assignment operation is happen it will take true condition.
    so it will print equal.
