Store RGB Image Data (Height × Width × Channels) Program Code

#include <stdio.h>
int main() {
    int height = 3, width = 4, i, j;
    unsigned char image[3][4][3];
    
    for(i =0;i<height;i++)
        for(j =0;j<width;j++) {
            image[i][j][0] = (i+j) * 30;  // Red channel
            image[i][j][1] = 0;            // Green channel
            image[i][j][2] = 0;            // Blue channel
        }
    
    printf("RGB Image (%d×%d):\n", height, width);
    printf("Pixel(0,0): R=%d G=%d B=%d\n", 
           image[0][0][0], image[0][0][1], image[0][0][2]);
    return 0;
