How to resolve errors in the clock function in C++?

If there is an error using the clock function in C++, it may be due to either not including the correct header file or not linking the correct library file. To resolve this issue, you can follow the steps below:

  1. Header file.
#include <ctime>
  1. Make sure to link the correct library files when linking. If you encounter an error when using the clock function, it may be because the library files are not linked correctly. You can include the -lrt parameter during compilation to link the time-related library files.
g++ -o program program.cpp -lrt
  1. If the first two steps do not solve the problem, you can try using another time function as a replacement for the clock function, such as the high-precision clock function in the chrono library.

I hope the above methods can help you solve the error when using the clock function. If the problem still persists, please provide more error information or code snippets for us to better assist you in resolving the issue.
