Question :   I have to design C++ code that calls a function. But I must not run that function for more than 2 seconds.   Answer Slow down young man, and let's proceed steadily. Shall we? Now what exactly you want to achieve is unclear here. Do you simply want to measure the execution time of the function? Do you want to terminate the program after the time limit is exceeded? Are you calling the function in a child process? Is your process running as a privileged user?The implementation obviously depends on what you want to do and what environments you are initializing the process with. Nevertheless, there are few different ways. I will get to them one by one with simplest first. 1. Measuring time You can easily measure the time (clock time & CPU time) taken to execute a function using clock() and time() functions available in the header <time.h>. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 #include <stdio.h>...
