Question

It’s a program that uses recursion to convert string to int
The code always outputs 17 when it’s supposed to output 1234
and when I add a digit to that number it adds 1 to that output
for example if it’s supposed to output 12345 it outputs 18

#include <cstdlib>
#include <iostream>

using namespace std;

int convertToInteger(string numberStr)
{
    if (numberStr.size()==0)  return result;
    convertToInteger (numberStr);
}

int main(int argc, char *argv[])
{
    string numberStr("1234");
    cout << numberInt << endl;
    return 0;
}

Answer 1

You’re missing a return before convertToInt (numberStr);
