Why does my program crash all the time. It's a simple program, only a
few lines:
int WIDTH=513;
int *mapheight;
void initmapheight(int *n)//allocateing memory
{
n=(int*)calloc((long)513*513,sizeof(int));
if(n==NULL)
exit(-1);
}
void reset(int *m,int W2)//set to zero. Here it crashes
{
for(int a5=0;a5<W2;a5++)
for(int q=0;q<W2;q++)
m[(long)a5*W2+q]=0;
}
void main(int argc, char *argv[])
{
initmapheight(mapheight);
reset(mapheight,100);
}
