Example: Transpose of a Square Matrix in C

// Transpose of a Square Matrix
#include <stdio.h>

#define SIZE 3 // Define the size of the square matrix

int main() {
    // Step 1: Declare and initialize the original square matrix
    int originalMatrix[SIZE][SIZE] = {
        {1, 2, 3},
        {4, 5, 6},
        {7, 8, 9}
    };

    // Step 2: Declare a new matrix to store the transpose
    int transposedMatrix[SIZE][SIZE];

    // Step 3: Print the original matrix
    printf("Original Matrix:\n");
    for (int i = 0; i < SIZE; i++) {
        for (int j = 0; j < SIZE; j++) {
            printf("%d ", originalMatrix[i][j]);
        }
        printf("\n");
    }

    // Step 4: Compute the transpose
    // Iterate through rows of the original matrix
    for (int i = 0; i < SIZE; i++) {
        // Iterate through columns of the original matrix
        for (int j = 0; j < SIZE; j++) {
            // Assign element at (i, j) of original to (j, i) of transposed
            transposedMatrix[j][i] = originalMatrix[i][j];
        }
    }

    // Step 5: Print the transposed matrix
    printf("\nTransposed Matrix:\n");
    for (int i = 0; i < SIZE; i++) {
        for (int j = 0; j < SIZE; j++) {
            printf("%d ", transposedMatrix[i][j]);
        }
        printf("\n");
    }

    return 0;
