'Local scope' basically means local to the function a symbol has been declared in, 'global scope' means global to the file a symbol has been declared in. As a simple example:
#include <iostream>
usinf namespace std;
 
int global = 23;  // global to this file
 
int main () {
 
  int local = 42; // local to 'main()'
 
  cout << "Global: " << global << " Local: " << local << endl;
 
  return 0;
}
