C Program to Swap Two Numbers without using Third Variable

1. Using + and –

Output:

Enter a: 10
Enter b: 20
The swapped values a: 20 and b: 10


2. Using * and /

Output:

Enter a: 10
Enter b: 20
The swapped values a: 20 and b: 10

Note that the swapping using / and * will not work if one of the swapping values is zero (0).
