Question

I cannot figure out why my code is breaking, and I could use some help.

First of all, the code:

Timer.h:

#include [...]

class Timer {
    public:
        [...]
        Timer operator+(double);
        [...]
    private:
        [...]
        void correctthedate(int day, int month, int year);
        [...]
};

Timer.cc:

#include "Timer.h"
using namespace std;

[...]

void correctthedate(int day, int month, int year) {
    [...]
}

[...]

Timer Timer::operator+(double plush) {
    [...]
    correctthedate(curday, curmonth, curyear);
    return *this;
}

When I try to compile I get the error:

Timer.o: In function `Timer::operator+(double)':
Timer.cc:(.text+0x1ad3): undefined reference to `Timer::correctthedate(int, int, int)'

Any pointers in the right direction? Thanks!

Answer 1

The following line:

void correctthedate(int day, int month, int year) {

should read

void Timer::correctthedate(int day, int month, int year) {

Otherwise you’re just defining an unrelated function called correctthedate().
