operator<= <array>
比较数组,低于或等于。
template<Ty, std::size_t N>
bool operator<=(
const array<Ty, N>& left,
const array<Ty, N>& right);
参数
Ty
元素的类型。N
数组大小。left
比较的容器。right
比较的正确的容器。
备注
模板函数返回 !(right < left)。
示例
// std_tr1__array__operator_le.cpp
// compile with: /EHsc
#include <array>
#include <iostream>
typedef std::array<int, 4> Myarray;
int main()
{
Myarray c0 = {0, 1, 2, 3};
// display contents " 0 1 2 3"
for (Myarray::const_iterator it = c0.begin();
it != c0.end(); ++it)
std::cout << " " << *it;
std::cout << std::endl;
Myarray c1 = {4, 5, 6, 7};
// display contents " 4 5 6 7"
for (Myarray::const_iterator it = c1.begin();
it != c1.end(); ++it)
std::cout << " " << *it;
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);
