Question

Write a complete program utilizing functions. The function accepts two parameters: one representing a radius of type float, the other parameter is an integer “select” which chooses between finding the area of a circle or the volume of sphere. If the select variable is 1, then area is calculated. If the select value is 2, then volume is calculated. If the select value is any other value, then the function returns 0. Test your function in main by calling it using different values for the “select” parameter. The return type is also float. Name the function whatever you wish.

Answer 1

here i am doing this in c language. f you need in another then comment below. i will do that

Enter radius: 4 Choose what you want : 1. Area 2. Volume 48.00 execution time : 2.239 S Process returned ? (@x?> Press any key to continue.

#include <stdio.h>
#include <math.h>
float sphere_volume(float radius,int select)
{
if(select==1)
{
float area = (22/7) * pow(radius, 2);
return area;
}
else if(select ==2)
{
float volume = (4.0/3) * (22/7) * pow(radius, 3);
return volume;
}
else
return 0;

}

int main()
{
float r;
int select;
printf("Enter radius: ");
scanf("%f",&r);
printf("Choose what you want:\n");
printf("1. Area\n2. Volume\n");
scanf("%d",&select);
printf("%.2f \n",sphere_volume(r,select));

}
