C Program to Read Two Integers M and N & Swap their Values

#include <stdio.h>
void swap(float *ptr1, float *ptr2);
void main()
 float m, n;
 printf("Enter the values of M and N \n");
 scanf("%f %f", &m, &n);
 printf("Before Swapping:M = %5.2ftN = %5.2f\n", m, n);
 swap(&m, &n);
 printf("After Swapping:M = %5.2ftN = %5.2f\n", m, n);
/* Function swap - to interchanges the contents of two items */
void swap(float *ptr1, float *ptr2)
 float temp;
 temp = *ptr1;
 *ptr1 = *ptr2;
 *ptr2 = temp;
