Is there a timer function in C++ ?

[Lana rose]

Hi

I have written some code but I want to know how long it takes to run the programme. I was wondering if there is a function similar to the tic toc function in matlab that I could embed within my code.

Your suggestions would be extremely appreciated.

Thanks

if you are working a Unix environment you can use the time command to run a program and get the elapsed time, cpu time, etc. see

you can use function clock() in <time.h> to measure the elapsed time since program startup, e.g. to measure elapsed time for a section of code

    time_t  start_time = clock();                              /*  get start time  */
........ code to measure
    float time1 = (float) (clock() - start_time) / CLOCKS_PER_SEC; 
    printf("time for code was %f seconds\n", time1);
 

the actual CPU time could well be different depending upon the number of processes running, etc
