Question

This code gives a compile-error on Topcoder. On code::blocks, it compiles with 0 errors and 0 warnings, the vector is printed, but it exits with a non-zero value, that causes windows to display “InterestingDigits.exe has stopped working”. Any help on this..?

#include<iostream>
#include<vector>
using namespace std;

class InterestingDigits
{
public:
vector <int> digits(int base)
{
    vector<int> v;
    for(int i=2; i<base; i++)
        if(base%i==1)
            v.push_back(i);
    for(int i=0; i<v.size(); ++i)
        cout<<v[i]<<" ";
    cout<<endl;
}
};

int main()
{
    int base;
    cin>>base;
    InterestingDigits id;
    id.digits(base);
    return 0;
}

It seems that your method digits() should return a value, a vector < int >.

Maybe adding a “return v;” at the end?
