Write a c program to rotate the matrix by k times in a clockwise direction using the function

Write a c program to rotate the matrix by k times in a clockwise direction using the function. In this program, you will learn how to rotate the matrix by k times in a clockwise direction using the function.

Take an example to make this clockwise rotation through a c program:

// Write a c program to rotate the matrix by k times
// in a clockwise direction using the function
#include <stdio.h>

// It's the matrix's dimensions
#define M 3
#define N 3

// It's the driver function
// to make clockwise rotation 
void rotateClockWise(int arru[][M], int k) {
    int temp[M];
    k = k % M;

    for (int i = 0; i < N; i++) {
        for (int t = 0; t < M - k; t++)
            temp[t] = arru[i][t];

        for (int j = M - k; j < M; j++)
            arru[i][j - M + k] = arru[i][j];

        for (int j = k; j < M; j++)
            arru[i][j] = temp[j - k];
    }
}

// This will display the matrix 
void displayMatrixData(int arru[][M]) {
    for (int i = 0; i < N; i++) {
        printf("\t");
        for (int j = 0; j < M; j++)
            printf("%d\t", arru[i][j]);
        printf("\n");
    }
}

int main() {
    int arru[N][M] = {
        { 12, 13, 14 },
        { 25, 26, 27 },
        { 38, 39, 31 }
    };
    int k = 2;

    printf("-----This is the given matrix before rotation-----\n\n");
    displayMatrixData(arru);

    // It will rotate matrix by k 
    rotateClockWise(arru, k);

    printf("\n\n------This is the given matrix after rotation %d times------\n\n", k);

    // It will display rotated matrix 
    displayMatrixData(arru);
    return 0;
}
