Ignoring the Voices: C++11 Example - Using auto as a Return Type

auto_return.cpp

#include <iostream>

#include "auto_return.h"

void Test::SetField(TestEnum t)
{
    _field = t;
}

auto Test::GetField() -> TestEnum
{
    return _field;
}

int main()
{
    Test t;
    t.SetField(Test::TestEnum::Two);
    
    auto val = t.GetField();
    std::cout << val << std::endl;
}

auto_return.h

class Test
{
public:
    enum TestEnum { One, Two, Three };
    void SetField(TestEnum t);
    TestEnum GetField();
private:
    TestEnum _field;
};
