C++ Error C202: 'CmdFlag' undefined identifier - Solution Guide

These errors are caused by the use of an undefined identifier 'CmdFlag' in the code. The compiler cannot find a definition for this identifier, which is used on lines 33, 37, and 102 of the main.c file.

To fix this error, you need to define 'CmdFlag' before using it in the code. This can be done by declaring it as a variable or by including a header file that defines it.
