Char Array not showing correctly

[Kalisto]

Looks like this is my week for questions, most of them probably have really easy answers.

I have allocated a char array as follows

char mArr[4] = {'0','0','0','0'};

itoa(data,&mArr,10);

But when it is displayed it shows a load of garbage.

When I display it to the screen, it shows 0002IIIIIIIITM/
I was expecting the 0002, but the rest is just garbage, and I don't see where it has come from when the array is explicity declared as 4 bytes, and data is a single 16 bit integer.

I have tried rewriting the code with a '\n' for the end of string, and making the array 5 cells, but it makes no difference.

I apologise if this is a real noddy question, but I usually use std::string, but want to use char[] here, and need to understand what I am doing wrong.

TIA,

K

Your mArr can only hold 3 chars + terminating zero. But where the zero should be you put a '2'. Hence the string is printed up to the first \0 it encounters.


/Per

_{if (typos) cout << &quot;My fingers are faster than my brain. Sorry for the typos.&quot;;}

Cheers, I'll try that later and fix it.
I new it would turn out to be something simple.

Nah, I just check in every now and then while compiling.
