Question

Sounds easy, but I’ve got a bug and I’m not sure what’s causing it?

nopunccount = 0;
char *ra = new char[sizeof(npa)];
while (nopunccount <= strlen(npa)) {
    ra[nopunccount] = npa[strlen(npa) - nopunccount]; 
    nopunccount++;
}

ra never gets a value into it and I have verified that npa has char values to provide within the nopunccount range.

Any help is appreciated // 🙂

Answer 1

nopunccountstarts as 0, so in the first iteration of the loop the character assigned to ra[0] is npa[strlen(npa)]. This is the terminating '\0' of that string. So the resulting string in ra starts with a '\0' and is therefore considered to be ending at that first byte by the usual string functions.
