Answer to Question #346457 in C++ for Ali

Question

We have a 4 x 4 two dimensional array. Fill it with random values from 1 to 100. Write a code to take transpose of the matrix. The following array is shown as an example:

1 2 3 4

5 6 7 8

9 10 11 12

13 14 15 16

BECOMES

1 5 9 13

2 6 10 14

3 7 11 15

4 8 12 16

Answer 1

#include <iostream>
#include <cstdlib>
#include <ctime>




using namespace std;


int main()
{
	srand(static_cast<unsigned int>(time(0)));
	const int m = 4, n = 4;
	int arr[4][4];
	for (int i = 0; i < m; i++)
		for (int j = 0; j < n; j++)
			arr[i][j] = rand() % 100;
	cout << "Random matrix: \n";
	for (int i = 0; i < m; i++)
	{
		for (int j = 0; j < n; j++)
			cout << arr[i][j] << " ";
		cout << endl;
	}
		
	for (int i = 0; i < m; i++)
		for (int j = 0; j < i; j++)
		{
			int tmp = arr[i][j];
			arr[i][j] = arr[j][i];
			arr[j][i] = tmp;
		}
	cout << endl;
	cout << "Transponse of the matrix: \n";
	for (int i = 0; i < m; i++)
	{
		for (int j = 0; j < n; j++)
			cout << arr[i][j] << " ";
		cout << endl;
	}
}
