ok! please dont laugh when u read my question!
I am new to programming!
I am trying to delete memory but I am not sure how!
Example:
unsigned char *bitmapImage; // bitmap image data
unsigned char *heightmapData; // the map image data
unsigned char *LoadBitmapFile(char *filename, BITMAPINFOHEADER *bitmapInfoHeader)
// allocate memory for the bitmap image data
bitmapImage = (unsigned char*)malloc(bitmapInfoHeader->biSizeImage);
..etc...
return bitmapImage;
}
// SEE HERE BELOW!!
void init()
{
heightmapData = LoadBitmapFile("heightmap/terrain.bmp", &bitmap1InfoHeader);
// deallocate memory
free(bitmapImage) // IS IT RIGHT! I DONT NEED IT ANYMORE, SO CAN I DELETE IT THIS WAY?
}
Now for example if I dont need the heightmapData too then how do I delete it? Note I am not using new or malloc see its declaration at the top!!!!
should I use a simple for loop and set all to 0 or there is another way in C++! Actually setting an array to 0 means that we deallocate memory or not?
Could I still use delete [] heightmapData even if I did not use the new operator? is it correct?
How do I free memory currently reserved by the heightmapData array?
Thanks for help!
