Programming in a nutshell

Pointers, my friend.

You should learn how variables work in their different contexts.

@CoolSonu39 as the others said: You need to use pointers. By default function basic type parameters are "pass-by-value", which means only the values of a and b are copied. When you change them in the function, they are not changed outside of it.

void swap(int * a, int * b) {
int * tmp = a;
a = b;
b = tmp;
}

sorry guys, the only thing (he and) you missed is that he is debugging noswap instead of swap 😁
