# C++ Exercises: Calculate the volume of a cylinder

## C++ Basic: Exercise-16 with Solution

Write a C++ program that calculates the volume of a cylinder.

Sample Solution:

C++ Code :

#include <iostream> // Including the input-output stream header file

using namespace std; // Using the standard namespace

int main() // Start of the main function
{
int rad1, hgt; // Declaring integer variables rad1 and hgt to store the radius and height of the cylinder respectively
float volcy; // Declaring a floating-point variable volcy to store the volume of the cylinder
cout << "\n\n Calculate the volume of a cylinder :\n"; // Outputting a message indicating the calculation of cylinder volume
cout << "-----------------------------------------\n"; // Outputting a separator line

cout << " Input the radius of the cylinder : "; // Prompting the user to input the radius of the cylinder
cin >> rad1; // Taking input for the radius from the user

cout << " Input the height of the cylinder : "; // Prompting the user to input the height of the cylinder
cin >> hgt; // Taking input for the height from the user

// Calculating the volume of the cylinder using the formula: π * radius^2 * height

cout << " The volume of a cylinder is : "<< volcy << endl; // Displaying the calculated volume of the cylinder
cout << endl; // Outputting a blank line for better readability

return 0; // Returning 0 to indicate successful program execution
} // End of the main function

Sample Output:

Calculate the volume of a cylinder :
-----------------------------------------
Input the radius of the cylinder : 6
Input the height of the cylinder : 8
The volume of a cylinder is : 904.32
