Hi,


what's wrong here:

const string Units[5]={"psek", "nsek", "musek", "msek", "sek"};

printf("%s\n", Units[1]);

Output is just the '\n', no "nsek".


thx,
michael

It seems that there is a bug with string array initialization. We don't recommand using string in a C array as Origin C has vector which suports string and vector is more reliable, and has basic support like GetSize(),

Try this


	const vector<string> Units={"psek", "nsek", "musek", "msek", "sek"}; 
	printf("%s\n", Units[1]);
	printf("3rd char is %c\n", Units[1][2]);


As for the array initialization bug, I have added a tracker 5457

Hi CP,

StringArray seems to work.

const StringArray saUnits = {"psek", "nsek", "musek", "msek", "sek"};
printf("%s\n", saUnits[1]);
printf("size=%d\n",saUnits.GetSize());

Is there a reason not to use that?

Hi Mike,

in <string.h>

typedef vector<string> StringArray;

so they are the same thing. I prefer using vector<string> just to be more accurate.

hi all,

i'm "native" C/C++ coder - so I tried to keep code as clean and "C-like" as possible.

But the StringArrays/vectors work very well. Thanks :-)

Michael
