Initialising variable with return value from a function

[applee]

Hi!
I'm wondering if it's possible to initialise a variable with a return value from a function like this:

int function()
{............. return a;}

int variable = function();

or

int function()
{............. return 5;}

int variable = function();

?
Thanks!

Yes you can do all those above examples you posted.

Yeah, it's fine to do that.

int func();


int main()
{
	int add = func();
	//the variable 'add' now equals 8

	return 0;
}


int func()
{
	int a = 5;
	int b = 3;

	int x = a + b;

	return x;
}

Not to nitpick but to save the cost of a temporary stack variable you can just do a

return a+b;

Yeah, I thought that as soon as I posted it, but left it there, lol.
