The following code produces 2 warnings with gcc 4.1.1: signed char * mystring = "Hello"; puts (mystring); warning: pointer targets in initialization differ in signedness warning: pointer targets in passing argument 1 of 'puts' differ in signedness Modifying the code as shown below corrects the problem: char * mystring = "Hello"; The same warnings occur is the char is declared unsigned. Does anyone know why this occurs? Thank you.
