Global variable in a recursive function how to keep it at zero?
- by Grammin
So if I have a recursive function with a global variable var_:
int var_;
void foo()
{
if(var_ == 3)
return;
else
var_++; foo();
}
and then I have a function that calls foo() so:
void bar()
{
foo();
return;
}
what is the best way to set var_ =0 everytime foo is called thats not from within itself. I know I could just do:
void bar()
{
var_ =0;
foo();
return;
}
but I'm using the recursive function a lot and I don't want to call foo and forget to set var_=0 at a later date.
Does anyone have any suggestions on how to solve this?
Thanks, Josh
