因此,我們沒辦法好好地使用 C++ Standard 的 min/max 這兩個 algorithms,也沒有辦法好好地使用 numeric_limits<>。前者 Microsoft 用了另外兩個宏命令,_MIN 與_MAX 來補救,但考量到跨平台程式設計,這兩個 macros 有跟沒有一樣。#define _MAX _cpp_max ——> const T& std::_cpp_max(const T&,const ...
1 #define MAX(x, y) (((x) > (y)) ? (x) : (y)) 2 #define MIN(x, y) (((x) < (y)) ? (x) : (y)) 以后使用MAX (x,y)或MIN (x,y),就可分别得到x和y中较大或较小的数。 但这种方法存在弊病,例如执行MAX(x++, y)时,x++被执行多少次取决于x和y的大小;当宏参数为函数也...
conio.h不是C标准库中的头文件。 conio是Console Input/Output(控制台输入输出)的简写,其中定义了通过控制台进行数据输入和数据输出的函数,主要是一些用户通过按键盘产生的对应操作,比如getch()函数等等。[编辑本段]包含的函数 包含的函数: cgets(char *); cprintf(const char *, ...); cputs(const char *)...
As far as I know, this will make <Windows.h> not define the min and max macros such that many conflicts with the STL, eg std::min()、 std::max() 或std::numeric_limits<T>::min() 已解决。 我是否正确地假设只有 Windows 特定和遗留代码会有问题?几乎所有的库都不应该依赖定义为宏的 min...

The MIN, MAX, and ABS macro definitions on OS X don't have the multiple expression evaluation problem unless you've defined STRICT_ANSI, IIRC.Pierre Lebeaupin at 2011-01-02 14:17:31:Psy beat me to the punch, but related to multi-line macros and X-Macros, you have the (to use ...
