Question

below is a dummy function. i saw something like this somewhere. i didnt understand the return part.

int SomeFunction(int SomeVar)
{
    //do the calculations
    ...
   return SomeVar != 0
}

how does the last line work? what does it return?

any help would be greatly appreciated.

Answer 1

This function returns 1 if SomeVar is nonzero and 0 if SomeVar is zero.

The result of expression SomeVar != 0 is of bool type (false or true). A bool type is implicitly converted to int (0 or 1 respectively).
