5 DIFFERENT WAYS TO SWAP TWO NUMBERS

Hi friends, here I'm posting 5 different ways to swap two numbers using any programming language like C,C++,Java etc.

             1.      // Easy n native way swapping using three variables (Takes extra memory space)

int a=2, b=5, c;

c=a;

a=b;

b=c;

2.      // using arithmetic operations

a=a+b;

b=a-b;

a=a-b;

3.       // using bit-wise operations

a=a^b;

b=b^a;

a=a^b;

4.      // one line statement using bit-wise operators

      //Most efficient way, less time consumption

a^=b^=a^=b;

//Same as 3 in on line

5.     // Most tricky way, one line way of 1

                  a=(a+b) - (b=a);
