In this post, we will learn how to calculate the cube root of a number using the C Programming language.
The cube root of a number is the factor that we multiply by itself three times to get that number. For example, the cube root of 64 is 4 since 4 x 4 x 4 = 64.
We will calculate the cube root using the cbrt() function.
So, without further ado, let’s begin this tutorial.
C Program to Calculate Cube Root of a Number
// C Program to Calculate Cube Root of a Number
#include <stdio.h>
#include <math.h>
int main(){
int number, root;
// Asking for input
printf("Enter a number: ");
scanf("%d", &number);
// Calculating cube root using cbrt() Function
root = cbrt(number);
// Displaying output
printf("Cube root of %d is: %d", number, root);
return 0;
}
Output
Enter a number: 125
Cube root of 125 is: 5
How Does This Program Work ?
int number, root;
In this program, we have declared two integer data type variables named number and root.
// Asking for input
printf("Enter a number: ");
scanf("%d", &number);
Then, the user is asked to enter a number to find it’s cube root. The entered value gets stored in the number named variable.
// Calculating cube root using cbrt() Function
root = cbrt(number);
The cbrt() function takes a single argument and returns the cube root of the number. The cbrt() function is defined in the math.h header file.
// Displaying output
printf("Cube root of %d is: %d", number, root);
The cube root of the entered number is displayed on the screen using printf() function.
