Example: Matrix Transpose using Separate Array in C++

// Matrix Transpose using Separate Array
#include <iostream>

using namespace std;

int main() {
    // Step 1: Define matrix dimensions
    int rows, cols;

    cout << "Enter the number of rows for the matrix: ";
    cin >> rows;
    cout << "Enter the number of columns for the matrix: ";
    cin >> cols;

    // Step 2: Declare original and transpose matrices
    int originalMatrix[rows][cols];
    int transposeMatrix[cols][rows]; // Dimensions are swapped for transpose

    // Step 3: Get input for the original matrix
    cout << "\nEnter elements for the original matrix:" << endl;
    for (int i = 0; i < rows; ++i) {
        for (int j = 0; j < cols; ++j) {
            cout << "Enter element originalMatrix[" << i << "][" << j << "]: ";
            cin >> originalMatrix[i][j];
        }
    }

    // Step 4: Print the original matrix
    cout << "\nOriginal Matrix (" << rows << "x" << cols << "):" << endl;
    for (int i = 0; i < rows; ++i) {
        for (int j = 0; j < cols; ++j) {
            cout << originalMatrix[i][j] << " ";
        }
        cout << endl;
    }

    // Step 5: Perform the transpose operation
    for (int i = 0; i < rows; ++i) {
        for (int j = 0; j < cols; ++j) {
            transposeMatrix[j][i] = originalMatrix[i][j];
        }
    }

    // Step 6: Print the transposed matrix
    cout << "\nTransposed Matrix (" << cols << "x" << rows << "):" << endl;
    for (int i = 0; i < cols; ++i) { // Note: iterate up to cols for rows of transpose
        for (int j = 0; j < rows; ++j) { // Note: iterate up to rows for cols of transpose
            cout << transposeMatrix[i][j] << " ";
        }
        cout << endl;
    }

    return 0;
