5. TRANSPUSA MATRICEI

#include <iostream>
using namespace std;

int main() {
    int n = 2, m = 3;
    int a[2][3] = {{1, 2, 3},
                    {4, 5, 6}};

    int t[3][2];  // transpusa: dimensiunile se inverseaza (m x n)

    for (int i = 0; i < n; i++)
        for (int j = 0; j < m; j++)
            t[j][i] = a[i][j];  // inversam indicii!

    cout << "Matricea originala (2x3):\n";
    for (int i = 0; i < n; i++) {
        for (int j = 0; j < m; j++)
            cout << a[i][j] << " ";
        cout << "\n";
    }
    cout << "Transpusa (3x2):\n";
    for (int i = 0; i < m; i++) {
        for (int j = 0; j < n; j++)
            cout << t[i][j] << " ";
        cout << "\n";
    }
    return 0;
}

Original A (2×3)	Transpusă T (3×2)	Relația
a[0][0] = 1	t[0][0] = 1	t[j][i] = a[i][j]
a[0][1] = 2	t[1][0] = 2	t[j][i] = a[i][j]
a[1][0] = 4	t[0][1] = 4	t[j][i] = a[i][j]
a[1][2] = 6	t[2][1] = 6	t[j][i] = a[i][j]
