Write a c program for swaping of two numbers

Answer 1

void swap(int *x,int *y)
{
int temp=*x;
*x=*y;
*y=temp;
}
This code snippet swaps the address of the two variables

Answer 2

#include <stdio.h>
int main() {
int x, y, temp;  
printf("Enter the value of x and y\n");
scanf("%d%d", &x, &y);  

temp = x;
x = y;
y = temp;

printf("After Swapping \n x = %d \n y = %d \n",x,y);   return 0;
}
