C ++比较一组值与给定的值(C++ comparing bunch of values with a given one)

 我需要比较一个给定值与检索值。 我在代码中多次执行此操作。 我对它的外观并不满意，我正在寻求某种util功能。 有人写过一个吗？ 
 
 我在比较的数值在编译时已知。 
 
 更新：我想摆脱容器，因为我知道确切数量的值（通常不超过3），我想与之比较。 每次将物品放入容器并不方便。 
 我不爱， 如果既不是因为它不明显就是“发现”。 
 
#include <algorithm>
#include <string>
#include <vector>

std::string getValue1()
{
    return "test";
}

std::string getValue2()
{
    return "the";
}

std::string getValue3()
{
    return "world";
}

int main()
{
    const std::string value = "the";

    // simple if
    if ( value == getValue1() ||
         value == getValue2() ||
         value == getValue3() )
        return 1;

    // using collections like vector, set
    std::vector<std::string> values;
    values.push_back( getValue1() );
    values.push_back( getValue2() );
    values.push_back( getValue3() );
    if ( values.end() != std::find( values.begin(), values.end(), value ) )
        return 1;

    // third option I'd use instead
    //

    return 0;
}

I need to compare one given value with a retrieved values. I do this several times in the code. I am not satisfied with how it looks and I am seeking for a some sort of an util function. Anyone wrote one? 
 
Number of values I am comparing with is known at the compile time.
 
Update: I'd like to get rid of containers as I know exact amount of values ( often not more then 3 ) I want to compare with. And it is not so convenient to put items to the container every time.
 I don't love if neither because it is not obvious as "find".
 
#include <algorithm>
#include <string>
#include <vector>

std::string getValue1()
{
    return "test";
}

std::string getValue2()
{
    return "the";
}

std::string getValue3()
{
    return "world";
}

int main()
{
    const std::string value = "the";

    // simple if
    if ( value == getValue1() ||
         value == getValue2() ||
         value == getValue3() )
        return 1;

    // using collections like vector, set
    std::vector<std::string> values;
    values.push_back( getValue1() );
    values.push_back( getValue2() );
    values.push_back( getValue3() );
    if ( values.end() != std::find( values.begin(), values.end(), value ) )
        return 1;

    // third option I'd use instead
    //

    return 0;
}
