Introduction
In this article, we will explore a C program to find the sum of cubes of elements in an array. This program is designed to calculate the sum of cubes of all the elements present in a given array.
We will provide a step-by-step explanation of the program along with relevant code snippets.
So, let’s dive in and understand how this program works.

What is the Sum of Cubes of Elements in an Array?
Before we proceed with the program, let’s first understand what the sum of cubes of elements in an array means.
When we have an array containing multiple elements, the sum of cubes refers to the summation of the cubes of each element in the array.
For example, if we have an array [1, 2, 3], the sum of cubes would be 1^3 + 2^3 + 3^3 = 1 + 8 + 27 = 36.

How Does the Program Work?
To find the sum of cubes of elements in an array, we will follow a straightforward approach.
Here are the steps involved:
- Start by declaring and initializing an array with a set of elements.
- Set a variable, let’s say
sum
, to store the sum of cubes. - Use a loop to iterate through each element of the array.
- Within the loop, calculate the cube of the current element using the formula
element * element * element
. - Add the calculated cube to the
sum
variable. - Repeat steps 3 to 5 for each element in the array.
- After the loop ends, the variable
sum
will hold the sum of cubes of all the elements in the array.

Now that we have a clear understanding of the program’s logic, let’s move on to the code implementation.
Code Implementation
#include <stdio.h>
int main() {
int array[] = {1, 2, 3, 4, 5};
int size = sizeof(array) / sizeof(array[0]);
int sum = 0;
for (int i = 0; i < size; i++) {
sum += array[i] * array[i] * array[i];
}
printf("The sum of cubes of elements in the array is: %d\n", sum);
return 0;
}

In the above code, we start by declaring and initializing an array with elements [1, 2, 3, 4, 5].
The size
variable calculates the number of elements in the array by dividing the total size of the array by the size of a single element.
Next, we initialize the sum
variable to zero.The for
loop iterates through each element of the array using the loop variable i
.
Inside the loop, we calculate the cube of the current element by multiplying it with itself three times. The result is then added to the sum
variable.
After the loop ends, we print the value of the sum
variable, which represents the sum of cubes of all the elements in the array.

FAQs (Frequently Asked Questions)
Yes, the program can handle negative numbers as well. The cube of a negative number is also negative, so the sum will include the cubes of negative elements accordingly.
Yes, for this program to work correctly, the array must contain at least one element. If the array is empty, the sum of cubes will be zero.
No, this program is specifically designed for a one-dimensional array. To find the sum of cubes in a 2D array, you would need to modify the program accordingly.
Yes, the program can handle large numbers without any issues. The size of the numbers in the array does not affect the program’s functionality.
o calculate the sum of cubes using floating-point numbers, you would need to declare the array as an array of floats or doubles, and modify the format specifier in the printf
statement accordingly.
Absolutely! You are free to use this program as a reference or incorporate it into your own C projects. Just make sure to understand the logic and modify it according to your specific requirements.
