function calls

[Finnla]

I have a question regarding function calls. If function with variable(s) calls another one, which calls another one ...etc, like a chain of function calls. Where and how are the memories(of variable for instance) stored/managed for each function calls? Are they stored in a single stack automatically? thank you very much in advance.

example code:

int func1 (int x){
    int a = x;
    a += func2(x);
    return a;
}

int func2 (int x){
    int a = x;
    a += func3(x);
    return a;
}

int func3 (int x){
    int a = x;
    a += func4(x);
    return a;
}

and so forth...
PS: I'm new to programming, just taking interest lately

All local variables will be stored on the stack.

Yep, your thinking is correct that it's a 'single' stack as well.
