Creating An Array Containing The Sum Of Each Column Elements

In this article, we'll explore how to create an array containing the sum of each column elements in a given 2D array.

As you have now understood the concept, first try to solve the problem by yourself before you look into the below solution.

Understanding the Problem

 Given a 2D array, our objective is to calculate the sum of elements in each column and store these sums in another array. Each element of the new array will represent the sum of elements in the corresponding column of the original array.


 Approach

 To create an array containing the sum of each column elements in a given array , we'll follow these steps:
Initialize Arrays

We'll create an array to store the sums of each column elements. The size of this array will be equal to the number of columns in the original array.


We'll iterate through each column of the original array and calculate the sum of elements in each column.


 We'll store the sums of each column elements in the new array.


Finally, we'll print the contents of the array containing the column sums.


Step-by-Step Solution

 Step 1: Initialize Arrays

 We'll start by creating an array to store the sums of each column elements. The size of this array will be equal to the number of columns in the original array.

Step 2: Calculate Column Sums

 Next, we'll iterate through each column of the original array and calculate the sum of elements in each column.

Step 3: Print the Results

 After calculating the sum of elements in each column and storing them in the array, we'll print the contents of the array containing the column sums.

Code Implementation

 Here's the complete code implementing the above approach:
