Check to see if all variable are equal to the same value in c++ [duplicate]

Answer 1

In C++11, you could use variadic templates to define your own function:

#include 

template
bool all_equal(T&& t, U&& u)
{
    return (t == u);
}

template
bool all_equal(T&& t, U&& u, Ts&&... args)
{
    return (t == u) && all_equal(u, std::forward(args)...);
}

int main()
{
    int x = 42;
    int y = 42
    std::cout << all_equal(42, y, x);
}
