Too much code for usergroup posts, give a link to your git repository 
instead, if you don't have one, gitlab and github offers you some space 
for free.

Seems to be the classic issue of not declaring variables/constants ahead 
of use.
Please try to follow C/C++ coding standard.

try/catch is a good way of handling issues that arises when you can't 
check if value exists or not before use.

Always be sure the value exists before you use it.
