c code to swap three numbers
write a c code to swap three numbers
Write a program that takes three variables (a, b, c) as separate parameters and rotates the values stored so that value a goes to be, b, b to c, and c to a by using SWAP(x,y) a function that swaps/exchanges the numbers x & y.
Code
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
void refrenceswap(int *a, int *b)
{
int temp;
temp = *a;
*a = *b;
*b = temp;
}
int main()
{
clock_t t;
t = clock();
int a, b, c;
printf("enter the three numbers to swap\n");
scanf("%d", &a);
scanf("%d", &b);
scanf("%d", &c);
int tempa = a;
printf("the value of a and b and c are : %d and %d and %d\n", a, b, c);
refrenceswap(&a, &b);
refrenceswap(&b, &c);
refrenceswap(&c, &tempa);
printf("the value of a and b and c are : %d and %d and %d\n", a, b, c);
t = clock() - t;
double time_taken = ((double)t) / CLOCKS_PER_SEC;
printf("\nfun() took %f seconds to execute \n", time_taken);
return 0;
