This is the beginning of snake game. Why function "atsiranda()" isn't called?

Apparently, obuolys1 and obuolys2 loses value when they are taken out of int main... what the heck is going on

I would highly suggest you reread whatever material you have that deal with functions. It seems you don't understand how programs have different scopes. By that I mean if you want to use a variable that is declared in main() in a function you need to pass that variable to the function through a parameter.

Here is a example.

int addNumbers(int numOne, int numTwo, int numThree)
{
    return numOne + numTwo + numThree;
}

int main()
{
    int one = 5;
    int two = 10;
    int three = 55;

    cout << addNumbers(one, two, three);
}


What the function is doing is saying whatever variables I pass into numOne, numTwo and numThree I want to add all their values together and return that sum.

So again reread up on functions because I don't think you totally get the idea behind them yet.

Also you cant do this
void goup(), goleft(), goright(), godown(), foxe(), atsiranda();
