Question

I have following function:

char * strAlloc(string str) {
    char * chArr = new char[str.size()];

    for (size_t i = 0; i < str.size(); i++) {
        chArr[i] = str[i];
    }

    return chArr;
}

if i do a break after char * chArr = new char[str.size()]; the debugger says following:

chArr   0x00c38cf8 "ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍýýýý««««««««þîþîþ"

and if i do a break after the for iteration i get this:

chArr   0x00c38cf8 "***************ýýýý««««««««þîþîþ"

so what i’m doing wrong?

edit:

size_t const gSize = 15; typedef char * 
TMaze [gSize]; 
Maze[0] = strAlloc ("***************");

in type TMaze i need the pointer of the char arrays tried also str.size()+1 ,
same behaviour

edit2:

char * strAlloc(string const & str) {
    char * chArr = new char[str.size()+1];

    strcpy(chArr, str.c_str());

    return chArr;
}

did it!

Answer 1

You’re not null terminating. Why not just use strcpy(chArr, str.c_str());?

And you’ll need to add one to your allocation, too: char* chArr = new char[str.size() + 1];
