@AWOL:
legal C?
Yes. Everything he posted was legal C and legal C++ (in bits and pieces). He just didn't post everything. I mean, really!
From the original post:
char StringFinal[40];
void setup()
{
Serial.begin(9600);
}
//CONCATENATE 5 STRINGS
// Good program design would not use a global variable, but might use a static array
// inside the function or some such thing. (Maybe pass the array name and size to
// the function and use strncat or some such thing.)
// Actually, I can't imagine that I would ever need a function that
// did nothing more than put five "strings" into an array.
//
// Oh, well...
//
// But as "proof of concept" I'll just use the original, exactly as in
// the first post.

char *concatena5(char *string1, char *string2, char *string3, char *string4, char *string5)
{
StringFinal[0]='\0';
strcat(StringFinal, string1);
strcat(StringFinal, string2);
strcat(StringFinal, string3);
strcat(StringFinal, string4);
strcat(StringFinal, string5);
return StringFinal;
}
void Escreve_Serial(char *sTexto)
{
Serial.println(sTexto);
}
void loop()
{
char * sHH;
char * sMM;
char * sSS;
sHH="21";
sMM="43";
sSS="00";
Escreve_Serial(concatena5(sHH,":",sMM,":",sSS));
while (1)
;
}
Output:
21:43:00
