WAP to swap two elements using the concept of pointers.
#include<stdio.h>
void swap(int *, int *); //prototype of the function
int main()
{
int a = 10;
int b = 20;
printf("Before swapping the values in main a = %d, b = %d\n",a,b);
swap(&a,&b);
printf("After swapping values in main a = %d, b = %d\n",a,b);
}
void swap (int *a, int *b)
{
int temp;
temp = *a;
*a=*b;
*b=temp;
printf("After swapping values in function a = %d, b = %d\n",*a,*b);
}
Output:
Before swapping the values in main a = 10, b = 20 After swapping values in function a = 20, b = 10 After swapping values in main a = 20, b = 10b. tech. bca c language tutorial learn c language mca study c language
