Swap Using Pointer

 #include <stdio.h>

void swap(int *x, int *y) {
    int temp;
    temp = *x;
    *x = *y;
    *y = temp;
}
int main() {
    int num1, num2;
    printf("Enter value of num1: ");
    scanf("%d", &num1);
    printf("Enter value of num2: ");
    scanf("%d", &num2);
    printf("Before Swapping num1 is: %d, num2 is: %d\n", num1, num2);
    swap(&num1, &num2);
    printf("After Swapping: num1 is: %d, num2 is: %d\n", num1, num2);

    return 0;
}
