**Write a program to transpose a matrix**

e.g.)
Input matrix. 1 2 3 4 5 6 7 8 9 Transposed matrix. 1 4 7 2 5 8 3 6 9

## C++ program to transpose a matrix

#include <iostream> #include <cstdlib> #include <ctime> using namespace std; int main() { srand(time(0)); int m = 3; int n = 3; int** matrix = (int**) calloc(sizeof(int), m); for ( int i = 0; i < m; i++ ) { matrix[i] = (int*) calloc(sizeof(int), n); } // Fill random values in the matrix for ( int i = 0; i < m; i++ ) { for ( int j = 0; j < n; j++ ) { matrix[i][j] = rand() % 100; } } // Print the matrix for ( int i = 0; i < m; i++ ) { for ( int j = 0; j < n; j++ ) { cout << matrix[i][j] << " "; } cout << endl; } cout << endl; // Transpose for ( int i = 0; i < m; i++ ) { for ( int j = i + 1; j < n; j++ ) { int tmp = matrix[i][j]; matrix[i][j] = matrix[j][i]; matrix[j][i] = tmp; } } // Print the transposed matrix cout << "Transposed matrix" << endl; for ( int i = 0; i < m; i++ ) { for ( int j = 0; j < n; j++ ) { cout << matrix[i][j] << " "; } cout << endl; } delete[] matrix; }Output:-

89 33 10 92 87 4 69 33 74 Transposed matrix 89 92 69 33 87 33 10 4 74
