The if Statement

[velaphi]

Hi

i want to swop the values of a and b if a < b:

if (a < b)
{
a = b;
b = a;
}

You'll need some temporary storage for data persistence.

if(a < b){
    //Assuming data types are of integers.
    int temp;
    temp = b;
    b = a;
    a = temp;
}

[yang]

a=a+b;
b=a-b;
a=a-b;

Thanx guys it really makes sense!

[ropez]

std::swap(a, b);
