DMA - Strings

Agincourt · 2001-11-20T20:14:57

I'm writing an implementation of C++ style strings for a class I'm taking, and I'm having a problem with my constructor. It looks like this - String::String(char * msg) { myLength = 0; while(msg[myLength] != '\0') { myLength++; } myString = new char[myLength]; for(int index = 0; index <= myLength; index++) myString[index] = msg[index]; } It's supposed to take a C-style string and convert it. It works most of the way, except sometimes it reads in an extra character of random memory. I'm not sure why it would work sometimes and not others. I assume the bug occurs in the constructor and not the printing because printing is supposedly the same as the last implementation (non Dynamic Memory Allocation). also, myString is a private data member declared as char *myString. if you can help that'd be great, if you need more info I'll check back real soon. thanks Use the WriteCoolGame() function Works every time Edited by - Agincourt on November 20, 2001 8:30:37 PM

got it, kind of. I was reading in the null terminated character and so that did mess up my output operator. It works if I print only up to myLength-1. Now to overload my addition operators correctly. hmmm. that can be my own problem. Thanks for all the help guys
