比較較大的 tuple 物件。

template<class T1, class T2, ..., class TN,
    class U1, class U2, ..., class UN>
    bool operator>(const tuple<T1, T2, ..., TN>& tpl1,
    const tuple<U1, U2, ..., UN>& tpl2);

參數

TN
第 n 個 Tuple 項目的型別。

備註

函式會傳回 tpl2 < tpl1。

範例

// std_tr1__tuple__operator_gt.cpp 
// compile with: /EHsc 
#include <tuple> 
#include <iostream> 
 
typedef std::tuple<int, double, int, double> Mytuple; 
int main() 
    { 
    Mytuple c0(0, 1, 2, 3); 
 
// display contents " 0 1 2 3" 
    std::cout << " " << std::get<0>(c0); 
    std::cout << " " << std::get<1>(c0); 
    std::cout << " " << std::get<2>(c0); 
    std::cout << " " << std::get<3>(c0); 
    std::cout << std::endl; 
 
    Mytuple c1 = std::make_tuple(4, 5, 6, 7); 
 
// display contents " 4 5 6 7" 
    std::cout << " " << std::get<0>(c0); 
    std::cout << " " << std::get<1>(c0); 
    std::cout << " " << std::get<2>(c0); 
    std::cout << " " << std::get<3>(c0); 
    std::cout << std::endl; 
 
// display results of comparisons 
    std::cout << std::boolalpha << " " << (c0 > c0); 
    std::cout << std::endl; 
    std::cout << std::boolalpha << " " << (c1 > c0); 
    std::cout << std::endl; 
 
    return (0); 
    }
