how to do swapping???

[Chervil]

this is not running

Please be specific. Does it fail to compile. Or does it run but then crash? Or does it give the incorrect output?

There's an error in the printf() statement.

This line:

    printf("a=%d\n=%d\n,a,b");

should read like so:

    printf("a=%d\nb=%d\n", a, b);

You have almost exactly the same mistake in the scanf() statement.
