Explanation: This program demonstrates the function diff_sc with some of the time differences in comparison and it helps in understanding the instantaneous time for switching or any other functionality to work. Here one option is given by entering the name of fav food and comparing and fetching t...
clock()是C/C++中的计时函数，而与其相关的数据类型是clock_t。它的具体功能是返回处理器调用某个进程或函数所花费的时间。函数返回从“开启这个程序进程”到“程序中调用clock()函数”时之间的CPU时钟计时单元（clock tick）数，其中clock_t是用来保存时间的数据类型。在time.h文件中，我们可以找到对它...
The clock function's era begins (with a value of 0) when the C program starts to execute. It returns times measured in 1/CLOCKS_PER_SEC (which equals 1/1000 for Microsoft C).See alsoLibrary FunctionsFeedback Was this page helpful? Yes No Provide product feedback | Get help at ...
clock returns the processor time used by program since the beginning of the execution, or -1 if unavailable. 这里提到clock()函数返回的是程序运行过程中耗掉得process time,也就是CPU time。 你以为它返回的是一个标准时间单位,你错了,因为还有下一句描述: clock() / CLOCKS_PER_SEC is a time in s...

is intended to be used by comparing it with the value returned from an earlier call toclock. For example, the first statement in themainfunction might be a call toclock; the difference between subsequent calls and the original call tell you how much time has elapsed since the program ...
<c |chrono Defined in header clock_tclock(void); Returns the approximate processor time used by the process since the beginning of an implementation-defined era related to the program's execution. To convert result value to seconds, divide it byCLOCKS_PER_SEC. Only the ...
