inline内联函数可以实现在调用函数的地方拷贝代码副本,从而避免了函数调用跳转等存在的时间上耗时稍长的问题。
(inline 要写在函数 定义 与 声明 之前,如 inline double square(double);
inline double square(double x){return x*x;})
内联函数的使用前提:
1.代码段比较小
2.且函数调用频...

C语言中的宏函数可以简化我们的操作。
但是存在一定的问题,宏函数是不能使用++a/a++,--a/a--这种形式的。这样会导致BUG(所得到的结果与预想结果不一致)。
原因就是宏函数是进行的文本拷贝,而不是传递的参数。
示例代码如下:
#include
using namespace std;
#define SQUARE(X) ((X)*(X))...
