C++ program to find sum of each row and columns of a matrix using user define function

// C++ program to find the Addition_Result of each row and column of a matrix

#include <iostream>
using namespace std;

// Get the size m and n
#define m 6
#define n 6

// Function to find Addition_Result of each row
void Adding_Rows(int T4Tutorials[m][n])
{

	int i,j,Addition_Result = 0;

	cout << "\nFinding Addition_Result of each row:\n\n";

	// finding the row Addition_Result
	for (i = 0; i < m; ++i) {
		for (j = 0; j < n; ++j) {

			// Add the element
			Addition_Result = Addition_Result + T4Tutorials[i][j];
		}

		// display the row Addition_Result
		cout
			<< "Addition_Result of the row "
			<< i << " = " << Addition_Result
			<< endl;

		// Reset the Addition_Result
		Addition_Result = 0;
	}
}

// User define Function to find Addition_Result of each column
void column_Addition_Result(int T4Tutorials[m][n])

	int i,j,Addition_Result = 0;

	cout << "\nFinding Addition_Result of each column:\n\n";

		for (j = 0; j < n; ++j) {

			// Add the element
			Addition_Result = Addition_Result + T4Tutorials[j][i];
		}

		// display the column Addition_Result
		cout

			<< endl;

		// Reset the Addition_Result
		Addition_Result = 0;
	}
}

// Driver code
int main()
{

	int i,j;
	int T4Tutorials[m][n];

	// Get the matrix elements
	int x = 1;
	for (i = 0; i < m; i++)
		for (j = 0; j < n; j++)
			T4Tutorials[i][j] = x++;

	// Get each row Addition_Result
	Adding_Rows(T4Tutorials);

	// Get each column Addition_Result
	column_Addition_Result(T4Tutorials);

	return 0;
}

Output

Finding Addition_Result of each row:

Addition_Result of the row 0 = 21
Addition_Result of the row 1 = 57
Addition_Result of the row 2 = 93
Addition_Result of the row 3 = 129
Addition_Result of the row 4 = 165
Addition_Result of the row 5 = 201

Finding Addition_Result of each column:

Addition_Result of the column 0 = 96
Addition_Result of the column 1 = 102
Addition_Result of the column 2 = 108
Addition_Result of the column 3 = 114
Addition_Result of the column 4 = 120
Addition_Result of the column 5 = 126
