This is my code for bubble sorting: Code: void CLEO_MedivisionView::OnNoiseremovalMedianfilter() { int n=[B][U]262144[/U][/B]; for(int x=0; x<n; x++) { for(int y=0; y<n-1; y++) { if(image[y]>image[y+1]) { int temp = image[y+1]; image[y+1] = image[y]; image[y] = temp; } } } } When i compile and run this set of codes, my application crashes. Somewhat i have a feeling that the array size of 262144 is the issue. when i just keyed in 262 for the array size (n), i get my image[0] to image[261] sorted in an increasing order. but i cant check for my array size of 262144. is this somewhat of a syntax error or some array overflow issue? what should i do? please help me on this thanks.
No idea; this worked fine for me (btw: see how much clearer the code is when properly indented): Code: int image[262144]; void main() { //int image1[10]={8,6,1,9,2,0,5,7,4,3}; int n=262144; int maxy1=0; for (int x=0; x<n; x++) { printf("setting image[%d]=%d\n",x,x%10); image[x]=x%10; } for (int x=0; x<n; x++) { printf("x iteration %d\n",x); for (int y=0; y<n-1; y++) { if (y+1>maxy1) maxy1=y+1; if (image[y]>image[y+1]) { int temp = image[y+1]; image[y+1] = image[y]; image[y] = temp; } } } printf("maxy1=%d\n",maxy1); for (int x=0; x<50; x++) { printf("%d ",image[x]); } printf("\n"); } Which version of which compiler are you using?
