Example: Matrix Transpose in C

// Matrix Transpose
#include <stdio.h>

int main() {
    // Define the original matrix (example 3x2)
    int original_matrix[3][2] = {{1, 2}, {3, 4}, {5, 6}};
    int rows = 3;
    int cols = 2;

    // Declare the transpose matrix with swapped dimensions (cols x rows)
    int transpose_matrix[cols][rows];

    printf("Original Matrix:\n");
    // Step 1: Print the original matrix to demonstrate its initial state
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j < cols; j++) {
            printf("%d ", original_matrix[i][j]);
        }
        printf("\n");
    }

    // Step 2: Compute the transpose
    // Iterate through the original matrix rows
    for (int i = 0; i < rows; i++) {
        // Iterate through the original matrix columns
        for (int j = 0; j < cols; j++) {
            // Assign element from original[i][j] to transpose[j][i]
            transpose_matrix[j][i] = original_matrix[i][j];
        }
    }

    printf("\nTransposed Matrix:\n");
    // Step 3: Print the transposed matrix
    // Note: When printing, iterate with the new dimensions (cols for rows, rows for cols)
    for (int i = 0; i < cols; i++) {
        for (int j = 0; j < rows; j++) {
            printf("%d ", transpose_matrix[i][j]);
        }
        printf("\n");
    }

    return 0;
