exercise 3 swap function

#include <stdio.h>// library
void swap(int *a, int *b){ // function and the definition. Void shows that the definition of the function is universal.
int temp= *a;
*a=*b;
*b= temp; }// This is saying that *b=*a but it is inferring it by having it = temp. use transitive property.

int main(void) {// main program.
  int M; // declare the variables as integers
  int N;
  printf("Enter values for M: ");
  scanf("%i",&M);
  printf("Enter the values for N: ");
  scanf("%i",&N);
  printf("Before swapping M: %d, N: %d\n",M, N); // This shows the results of the numers before the swap.
  swap(&M,&N); //Function call
  printf("After swapping M: %d, N: %d",M,N);
  return 0;
