之所以起这个别名,是因为表意的需要。 比如size_t 就是表达代表“容量”的一个类型,但它本质就是 unsigned int time_t 和 clock_t 也是如此,设计这两个类型的语义虽然不同,但他们本质都是 long long,所以都可以用于接收 clock() 的返回值。 继续加油!:) 0 回复 收起回答 提问者 IT_god #1 非常感谢!
clock_t应该是滴答数。正常人都有time_t，表示自1970以来的秒数。具体用法可以“C/C++学习指南 邵发" 的这个书，在线教程，第16章里有time.h里的大部分函数的用法。
计时器的time_t和clock_t的两种实现⽅法（推荐）想给⾃⼰初步完成的相空间搜索算法计算⼀下运⾏时间，于是尝试了如下使⽤ time_t 类型的⽅式 #include <stdlib.h> #include <iostream> #include <time.h> #include "StateFunctions.h"using namespace std;int main(int argc, char** argv){ t...
cout << "--> time: " << duration << " s" << endl; cout << "---" << endl; return 0; 这种实现方式可以正确计算出算法的核心部分耗费了234秒的 walltime。在此之前尝试的使用 clock_t 类型的实现方式是 #include <iostream> #include <time.h> #include "StateFunctions.h" using namespace...

What time is it?Most people are pretty accurate in their answer. And if you don’t know for sure, it’s very likely that you can find out. There may be a watch on your wrist; there may be a clock on the wall, desk, or computer screen; or maybe you’re riding in a car that...
