下面是显示所有数据类型最常见的numeric_limits函数的程序: C++ // C++ program to demonstrate the use // possible numerical data types // that supports std::numeric_limits #include #include #include #include #include #include struct RowPrinter { // Left alignment int m_left; // Right alignment...
The std::numeric_limits class template provides a standardized way to query various properties of arithmetic types (e.g. the largest possible value for type int is std::numeric_limits<int>::max()). This information is provided via specializations of the std::numeric_limits template. The sta...

而std::endl是C++中的换行符,它会在输出内容的末尾插入一个换行符,并刷新输出缓冲区。 在条件if中使用std::endl和string是完全合法的,但是有一些情况下可能不被推荐使用。下面是一些相关的考虑因素: 性能:std::endl会刷新输出缓冲区,这意味着每次使用std::endl都会导致输出立即显示在控制台上。如果...
