Hi,
Sorry for asking a naive question but I have been trying to create and
manipulate an array
of strings in NXC without much success. Here is the little test program that
I use:
#include "NXCDefs.h"
task main() {
string sarr[];
ArrayInit(sarr, "*",3);
string s1 = "hello";
string s2 = "world";
sarr[0]=s1;
sarr[1]=s2;
string ss1 = sarr[0];
string ss2 = sarr[1];
string tmp = StrCat(ss1, ss2);
TextOut(0, LCD_LINE1, tmp);
Wait(3000);
}
I would have expected the string "hello world" to be printed. However, "* *"
is printed instead.
It seems that the value assignment operators for sarr's elements did not
work.
Am I using the right syntax?
Any help is much appreciated.
Thanks,
Duc
