How do you determine the size of a file in C?
...
Matt's solution should work, except that it's C++ instead of C, and the initial tell shouldn't be necessary.
unsigned long fsize(char* file)
{
FILE * f = fopen(file, "r");
fseek(f, 0, SEEK_END);

fclose(f);

Why do x86-64 systems have only a 48 bit virtual address space?
...ought the definition of portable software is that it can. :-) For example, C++ forbids comparing pointers into different arrays so that they can be in separate 4GB segments.

Mod of negative number is melting my brain
...
Please note that C# and C++'s % operator is actually NOT a modulo, it's remainder. The formula for modulo that you want, in your case, is:
float nfmod(float a,float b)
{
return a - b * floor(a / b);
}
You have to recode this in C# (or C++) bu...

How do you implement a class in C? [closed]
Assuming I have to use C (no C++ or object oriented compilers) and I don't have dynamic memory allocation, what are some techniques I can use to implement a class, or a good approximation of a class? Is it always a good idea to isolate the "class" to a separate file? Assume that we can preallocate t...
