C Program to compute Volume of the Cone

Overview

In this tutorial, we will develop a C program to compute the volume of the cone. We will use the Code::Blocks IDE to develop the C Program.

Steps to download and install the IDE on the Windows operating system:

Download & Install Codeblocks

C Program

Develop the C Program.

The general steps of the program are as follows:

Create a C project and C source file.
Declare the variables to hold height, radius, and volume.
Get the radius and height of the code from the user. Store the values to the respective variables in the C program.
Compute the Volume of the cone as per the mathematical formula.
The volume of the cone = (pi * radius* radius* height)/3
Display the volume on the computer screen.
