Only if you're using -ffreestanding (e.g., in order to get GCC to accept a return type "void" for main()). If you're using -fhosted (the default), and optimize, it will simply result in A_String[16] = 0; because the compiler is allowed to use internal library knowledge in hosted mode. (The compiler would even be allowed to optimize the sprintf() case, but by now, it doesn't do that.) -- cheers, J"org .-.-. --... ...-- -.. .
