WebApr 10, 2024 · c++ 利用析构函数计时. 在 C 语言中，可以使用 clock() 函数来计算程序的运行时间。首先，在程序开始运行时，应该调用 clock() 函数，并将返回值赋给一个变量，例如： clock_t start= clock(); 然后，在程序结束运行时，再次调用 clock() 函数，并将返回值赋给另一个变量，例如： clock_t end= clock(); 最后，通过 ... Websteady_clock. Class std::chrono::steady_clock represents a monotonic clock. The time points of this clock cannot decrease as physical time moves forward and the time between ticks of this clock is constant. This clock is not related to wall clock time (for example, it can be time since last reboot), and is most suitable for measuring intervals.
