Question

I have a function “void foo()” and inside foo I call the function “void bar()”
but I keep getting the error “In function ‘void foo()’ error: function ‘bar’ was not declared in this scope”.

I have done some research and can’t seem to find anything that helps.
Does anyone know the issue? I’m sure it’s probably simple but can’t find the answer.

Answer 1

You haven’t declared the function before you use it.

Try something like:

void bar(); //declaration
void foo()
{
   bar();
}

Alternatively, if bar() is declared in a different header, you can include that header instead. Or you could define bar() before foo() (unless of course bar() uses foo()).
