I have a task to check a string if it contains non-numbers in it and then remove those.
I tried this code below and it doesn't work. Could someone point out what's wrong with my code?
recursiveNAN(string num, int pos) { char tmp=num[pos]; if(pos<0) { this->create(); //allocates memory for the new number *this->num = stoi(num); //translate string to number } if (isdigit(tmp)&&pos>=0) { this->recursiveNAN(num, pos-1); } else if (!isdigit(tmp) && pos>=0) { num.erase(pos,1); this->recursiveNAN(num,pos-1); } }
It doesn't say any errors while compiling but it does while debugging.
