warning: excess elements in scalar initializer

[helmut januschka]

hi !,

Following Code gives me following error's
warning: excess elements in scalar initializer
char *functionname = {

"abs", "sqrt", "sin", "cos", "atan", "log", "exp", "\0"

};

best regards

That's because your initializer is for an array of pointers to char, while
functionname is just a pointer to char (a scalar). What you want, probably
is:

char *functionname[] =
{ "abs", "sqrt", "sin", "cos", "atan", "log", "exp", "\0", };

-nrk.

Sure, you want an array :

char const *functionname[] =
{
"abs", "sqrt", "sin", "cos", "atan", "log", "exp", NULL
};

(The NULL thing is probably useless...)

Not at all. The NULL thing is more useful than the "\0" thing to be
sure. Consider..

for (i = 0; functionname[i] != NULL; ++i)
puts(functionname[i]);

...or..

for (i = 0; *functionname[i] != '\0'; ++i)
puts(functionname[i]);

I like the NULL treatment best.

The old C-string vs Pascal-string discussion is back!

I don't think my response did it but yours now does. The Pascal 'string'
has a leading unsigned char (0..255) to indicate the length of the
string. How would Pascal present a 300 character string?
