i have seen in some places of coding where a function is used in return statement. Why is it done? Any advantage?
Example
I hope it is only the style of coding. Am I correct?Code:int SubFunction1(void) { return subfunction2(); } int Subfunction1(void) { int local; local = subfunction2(); return local; }
Static functions in C
Static functions jump to mind - You may have a variable restricted to a certain file and need to use it as an argument
> I hope it is only the style of coding. Am I correct?
Yes you are correct.
Using a local variable is perhaps convenient if you need to examine a function return value in a debugger.
Especially when you don't have the source for the called function.
Any decent compiler will optimise away the local variable anyway.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
