functions position

[alexBB]

I have Ubuntu 14.04 and Linux g++ compiler for c++14

I have a strange situation. Let's consider a large program with two functions located far apart:

function_1 (int B) {    // line 950
  Locations loc;  // I get an error here: Locations aren't defined      
  ......
  loc.function_2 (5.0);
  ......
} 

class Locations {
......................
function_2 (double C) {       // line 2010
  ........
}
}

As evident from the code. I get a compile error in line 951: Locations aren't defined in this code.

Does it mean that all classes and functions must be defined BEFORE they are called in the source code?

It this is true, it is a terrible news.

Thanks, - Alex

yes. Variables too.

¿why?
Also, old news.
