Question

Pyramid of oranges, 2^x in each row, total for n rows using scheme language also include comments

Answer 1

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

#include <iostream>
using namespace std;

// Get the size m and n
#define m 4
#define n 4

// Function to calculate sum of each row
void row_sum(int arr[m][n])
{

   int i,j,sum = 0;

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

   // finding the row sum
   for (i = 0; i < 4; ++i) {
       for (j = 0; j < 4; ++j) {

           // Add the element
           sum = sum + arr[i][j];
       }

       // Print the row sum
       cout
           << "Sum of the row "
           << i << " = " << sum
           << endl;

       // Reset the sum
       sum = 0;
   }
}

// Function to calculate sum of each column
void column_sum(int arr[m][n])
{

   int i,j,sum = 0;

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

   // finding the column sum
   for (i = 0; i < 4; ++i) {
       for (j = 0; j < 4; ++j) {

           // Add the element
           sum = sum + arr[j][i];
       }

       // Print the column sum
       cout
           << "Sum of the column "
           << i << " = " << sum
           << endl;

       // Reset the sum
       sum = 0;
   }
}

// Driver code
int main()
{

   int i,j;
   int arr[m][n];

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

   // Get each row sum
   row_sum(arr);

   // Get each column sum
   column_sum(arr);

   return 0;
