Why you should care
[/vc_column_text][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]
Global variables should be encapsulated in a class and doing so can make code more productive.

How we detect
[/vc_column_text][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]This code insight counts a violation each time there are too many global variables
int m_iGlobal = 0;
void m()
{
m_iGlobal = 1; // VIOLATION
}
Remedy
Create a static data member in the appropriate class to replace the global variable.[/vc_column_text][vc_row_inner][vc_column_inner width=”1/1″][vc_single_image image=”5362″ img_link_large=”” img_link_target=”_self” img_size=”full” alignment=”none”][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]
