If you want to mesure how long the entire program run's, then Code-Blocks/Visual studio should tell you when the program closes. It should be in the log at the bottom.

If you want to mesure how long a specific line, or function takes, I would suggjest researching clock() or QueryPerformanceFrequency() and how to use them.

the clock() function is slow, but it's easyer to use. an example:

float start_time = clock()/CLOCKS_PER_SEC;
func();
float end_time = clock()/CLOCKS_PER_SEC;
float dtime = start_time - end_time;
