Hey guys Im having a probelm with my algorithm . Im trying to copy data from a asci ppm file(which is just a text file really) into a 2-d array of structs. The order it should go in is plot[1][1],plot[1][2].....plot[2][1]..and so on.
Here is the code
Code:
//the class
class graphics
{
public:
void loadPPM(char* filename);
graphics(void);
~graphics(void);
private:
int xsize;
int ysize;
struct RGB
{
int red;
int green;
int blue;
}plot[100][100];
};
Code:
//the algorithm
for(i=1;i<=xsize;i++)
{
for(j=1;j<=ysize;j++)
{
for(k=1;k<=3;k++)
{
inFile>>plot[i][j].red;
inFile>>plot[i][j].green;
inFile>>plot[i][j].blue;
}
}
}
cout<<filename<<endl;
cout<<plot[1][1].red<<endl;
cout<<plot[1][1].green<<endl;
cout<<plot[1][1].blue<<endl;
Code:
....
//the text file im reading
255
255
254
251
255
255
//there are over 4400 lines like but its not relevent
Im not getting the currect output when I run the program. My results are 251,255,254. It should be 255,255,254. I think I have a problem with the nested for loops. If you would to see more code. Like the function call, I will post it.
Thanks
Chris
