c code for swapping
how to swap in c using call by value and reference
write a program to swap two integers using call by value and call by reference method by passing argument to the function.
Code
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
void callswap(int a ,int b){
int temp;
temp = a;
a = b;
b = temp;
}
void refrenceswap(int *a ,int *b){
int temp;
temp = *a;
*a = *b;
*b = temp;
}
int main(){
int x,y;
printf("enter the two numbers to swap\n");
scanf("%d",&x);
scanf("%d",&y);
callswap(x,y);
printf("the value of a and b are : %d and %d\n",x,y);
refrenceswap(&x,&y);
printf("the value of a and b are : %d and %d\n",x,y);
return 0;
}
