What is wrong with this code??? (resolved)

[MoMad]

[SIZE=24pt]Woooohooo it works!! (resolved)[/SIZE]

This code will not run no matter what!!! I tried everything... its the function thats causing it to crash??

Here;s the code.

// Temp2.cpp : Defines the entry point for the console application.
//

#include <iostream.h>
#include <math.h>
#include <stdio.h>


struct nTemp
{
	unsigned char Temp[18][256][256];
};

void saveIt(void);
nTemp loadIt(void);

int main(int argc, char* argv[])
{
	saveIt();
	// thats all.

	cout << "Saved!" << endl;
	cin.ignore();

	return 0;
}

void saveIt(void)
{
	long temp = 0;
	long effect = 0;
	long src = 0;
	long dest = 0;
	nTemp myTemp;
	FILE* f = 0;

	cout << "Saving....\n";
	for( effect = 0; effect < 18; effect++ )
	{
		cout << "Effect: \t\t" << effect << endl;
		for( dest = 0; dest < 256; dest++ )
		{
			for( src = 0; src < 256; src++ )
			{
				switch( effect )
				{
				case 0:
					// Add
					temp = (temp = src + dest) > 255 ? 255 : temp;
					break;
					
				case 1:
					// Subtract
					temp = (temp = dest - src) < 0 ? 0 : temp;
					break;
					
				case 2:
					// Subtract (corrected)
					temp = (temp = dest - (255 - src)) < 0 ? 0 : temp;
					break;
					
				case 3:
					// Better Add Effect (Alpha Map to White)
					temp = (((255 - src) * (dest + 1)) >> 16) - src;
					break;
					
				case 4:
					// Better Subtract Effect (Alpha Map to Black)
					temp = ((src * (dest + 256)) >> 16) - src;
					break;
					
				case 5:
				case 6:
				case 7:
				case 8:
				case 9:
				case 10:
				case 11:
				case 12:
					// Translucency (5 to 12)
					temp = (src > 0) ? ((effect - 3) * ((dest + 11) - src)) / 11 + src - (effect - 3) : dest;
					break;
					
				case 13:
					// Weird Effects (13 - 17)
					temp = (src > 0) ? ((temp = (dest * atan(dest / src))) > 255 ? 255 : ((temp < 0) ? 0 : temp)) : dest;
					break;
					
				case 14:
					// Weird Effects (13 - 17)
					temp = (src > 0) ? ((temp = (dest * sqrt(dest / src))) > 255 ? 255 : ((temp < 0) ? 0 : temp)) : dest;
					break;
					
				case 15:
					// Weird Effects (13 - 17)
					temp = (src > 0) ? ((temp = (src * sin(dest / src))) > 255 ? 255 : ((temp < 0) ? 0 : temp)) : dest;
					break;
					
				case 16:
					// Weird Effects (13 - 17)
					temp = (src > 0) ? ((temp = (src * cos(dest / src))) > 255 ? 255 : ((temp < 0) ? 0 : temp)) : dest;
					break;
					
				case 17:
					// Weird Effects (13 - 17)
					temp = (src > 0) ? ((temp = (sqrt(dest) * sqrt(src))) > 255 ? 255 : ((temp < 0) ? 0 : temp)) : dest;
					break;
					
				//default:
					// if no effect selected, do nothing.
					// return;
				}
				
				myTemp.Temp[effect][dest][src] = temp;
			}
		}
	}

	// now write it to a file.
	f = fopen("spfx.dat", "w+b");
	fwrite(&myTemp, 1, sizeof(myTemp), f);
	fclose(f);
}

nTemp loadIt(void)
{
	FILE* f = NULL;
	nTemp s;
	cout << "Loading...\n";
	f = fopen("spfx.dat", "r+b");
	fread(&s, 1, sizeof(s), f);
	fclose(f);

	cout << "Loaded!" << endl;
	cout << "Temp[3][6][9] = " << s.Temp[3][6][9] << endl;
	return s;
}

Sorry, it doesnt wrap...
