Slip 12 - B) Accept two numbers from user and write a menu driven program to perform the following operations 1. swap the values of two variables 2. calculate arithmetic mean and harmonic mean of two numbers

Solution:

#include<stdio.h>

void main()

{

    int n1,n2,t,choice;

 

         float arithmetic_mean,harmonic_mean;

    printf("\n Enter the radius of circle:- ");

    scanf("%d%d",&n1,&n2);

    printf("\n Please make a choice from the following :");

    printf("\n \n Options:\t \t \t \t");

    printf("Actions:");

    printf("\n \n 1. SWap :");

 

    printf("\n \n 2. MEAN ");

     

    scanf("%d",&choice);

    switch(choice)

    {

    case 1:

                   t=n1;

                   n1=n2;

                   n2=t;

        printf("\n swap=%d %d \n \n",n1,n2);

    break;

 

 

    case 2:

     

 

     arithmetic_mean = (n1+n2) /2;

    harmonic_mean = (n1*n2) / (n1+n2);

   printf("arithmetic mean = %f and harmonic mean = %f",arithmetic_mean,harmonic_mean);

    break;

    default:

    printf("\n You haven made invalid choice \n \n");

    }

} // End of the code
