Too many global variables can be unproductive

Software ResiliencyCode Reliability

Why you should care

Global variables should be encapsulated in a class and doing so can make code more productive.

How we detect

This code insight counts a violation each time there are too many global variables

int m_iGlobal = 0;

void m()
m_iGlobal = 1; // VIOLATION


Create a static data member in the appropriate class to replace the global variable.
