July 25, 2005 Literal Strings as const char *? | ||||
---|---|---|---|---|

I am a little confused. Am using DMC 8.44 (beta) which in which literal strings are taken as constant. Except when they aren't... Given the following void foo (char *); main () { char *p = "hello"; int f= 1; foo("hello"); foo(p); foo (f ? "a" : "b"); foo (f ? p : "b"); } foo (f ? "a" : "b"); ^ test.cpp(9) : Error: need explicit cast for function parameter 1 to get from: char const * to : char * foo (f ? p : "b"); ^ test.cpp(10) : Error: need explicit cast for function parameter 1 to get from: char const * to : char * --- errorlevel 1 It seems to me that the first of the function calls should be an error. Except - I guess - that this would break so much existing code as to be useless. But then if we are to allow that, then why not the tertiaries? Cheers, John. |
