Write a program that swap two integer by function call

Input:

//Write a program that swap two integer by function call (passing by reference/address)

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

#include<stdio.h> void swap(int *x, int *y) { int temp; printf("x = %d, y = %d \n", x, y); temp = *x; x = *y; y = temp; printf("x = %d, y = %d\n\n", x, y); } void main() { int x = 5; int y = 10; swap(x,y); //passing by reference/address }

Output:

x = 5, y = 10
x = 10, y = 5
