@Luchian Grigore I'm using this code your provided but I want to change "Guy" into a const varaible.
 
Can you please help me understand what the different between the following implementation ( all work fine) :
 
    char * const AUTHOR_NAME = "GUY";
 
    static char * AUTHOR_NAME = "GUY";
 
    char * AUTHOR_NAME = "GUY";
 
 
All these are above the main.
 
For some reason the following line didn't work for me : 
 
    char * const AUTHOR_NAME = "GUY";
 
Thaks,
Guy
