Use pointers to replace the value of two variables

   

Hey guys once again welcome to the Decoders blog, I hope you all are doing well and today I'm present with another logic but this time with something different it is a C logic which will replace the values of two variables using the pointers 

Here's the code which you can go through...........

#include<stdio.h>

int main()

{

    int a,b;

    int *ptra,*ptrb;

    //Using pointers to replace the two variables

    printf("Enter the values of a and b:\n");

    scanf("%d%d",&a,&b);

    printf("The value of a is %d\n",a);

    printf("The value of b is %d\n",b);

    ptra=&a;

    ptrb=&b;

    printf("The value of a is %d\n",*ptrb);

    printf("The value of b is %d",*ptra);

}
