C++, C String, Character Array and character pointer
C-String can be represented in 3 different ways
1. C-String as string literal : string name= "CIT 126 Professor";
cout name ; // display "CIT 126 Professor"
2. C-String as array of character: char professorName[] = "Professor Liu";
cout professorName ; // display "Professor Liu"
3. uses a pointer to char to point to a C-String whose storage has already been allocated by the first or second method:
char* p;
p = professorName;
cout p ; // display "Professor Liu"
