Question

C++ Code! Represent the following matrix using a two-dimensional array and write a nested for loop to initialize the elements (do not initialize the array in the declaration):

10  9   8
7   6   5
4 3   2

Answer 1

Here is code:

#include <iostream>

using namespace std;

int main()
{
int ROWS = 3,COLS = 3;
int arr[ROWS][COLS];
int counter = 10; // counter assign the values
// loops rows
for(int i = 0 ; i < ROWS ; i++)
{
// loops cols
for(int j = 0 ; j < COLS ; j++ )
{
arr[i][j] = counter--;
}
}
//prints the matrix
cout << "Matrix array is :" << endl;
for(int i = 0 ; i < ROWS ; i++)
{
for(int j = 0 ; j < COLS ; j++ )
{
cout << arr[i][j] << " ";
}
cout << endl;
}

return 0;
}

Output:
