How to write a C program to find the volume of a can of milk

Answer 1

#include <stdio.h>

#include <math.h>

int main() {

double radius, height, volume;

printf("Enter the radius of the can (cm): ");

if (scanf("%lf", &radius) != 1 || radius <= 0) {

printf("Error: Please enter a valid positive number for the radius.\n");

return 1; // Exit with error

}

// Get user input for height

printf("Enter the height of the can (cm): ");

if (scanf("%lf", &height) != 1 || height <= 0) {

printf("Error: Please enter a valid positive number for the height.\n");

return 1; // Exit with error

}

// Calculate volume

volume = PI * pow(radius, 2) * height;

// Display result

printf("The volume of the can is: %.2lf cubic cm\n", volume);

return 0; // Successful execution

}

Answer 2

/**************************************************************

Calculates the volume of the cylinder:

Given radius R and height H, the volume is

pi* R^2 * H

*******************************************************************/

#include <stdio.h>

int main()

{

double radius;

double height;

double volume;

printf(" Please input the radius of the cylinder :>");

scanf("%lf",&radius);

printf(" Please input the height of the cylinder :>");

scanf("%lf",&height);

volume = 22.0/7 * radius * radius * height;

printf(" The radius = %12.5f \n",radius);

printf(" The height = %12.5f \n",height);

printf(" The Volume = %12.5f \n",volume);

}
