Check if element is in the list (contains)

Question

I\'ve got a list of elements, say, integers and I want to check if my variable (another integer) is one of the elements from the list. In python I\'d do:

my_list         


        

Answer 1

Declare additional helper function like this:

template 
bool vectorContains(const vector& v, I& t)
{
    bool found = (std::find(v.begin(), v.end(), t) != v.end());
    return found;
}

And use it like this:

void Project::AddPlatform(const char* platform)
{
    if (!vectorContains(platforms, platform))
        platforms.push_back(platform);
}
