#include #include #include #include using namespace std; const int SIZE = 150;

class color { protected: int a[SIZE][SIZE*3]; int m; int n;

public: color(); color(unsigned char, unsigned char, unsigned char); unsigned char r; unsigned char g; unsigned char b; static const int Width = 240; static const int height = 320; int getM()const; void setM(int m); int getN()const; void setN(int n); void writeppm(string); void createpicture();

} void color::createpicture(){ color grey(127,127,127);

for(int i = 0; i

int main() { color X; X.createpicture(); X.writeppm("image1.ppm"); cout

I am not gettint the image -getting the pm, width height - but no image no cout image has been created - what I'm I doing wrong? thanks C++

Problem with your code:

m and n are not set. m was found to be -2144153320 and n was 1 and hence the loop didnot work. NOTE that both the values are garbage values since m and n are never set in the code you provided.

We must set m and n to their default values inside the constructor (both default and parameterized). That should make the code work as intended.

I hope this resolves your issue. If this does not resolve your issue, please let me know. Shall help you to resolve the issue.
