At the beginning, i searched google for time functions and tried to use the time() function before and
after the for loop with no success.
After asking for help, i was told to use the clock() function instead of time.
After doing so, i got the following results:
For 100,000,000 time of increasing j by one (starting at J = 0):
Every time i run the test, a slitlty diffrent result is producted. I think this is due to how busy the processor and/or ram are on the time of running the test.
On PC (Windows vista), the results are as follows:
Rounds First Second Third int: 286 ticks || 288 ticks || 289 ticks long: 305 ticks || 288 ticks || 302 ticks short: 340 ticks || 297 ticks || 288 ticks double: 342 ticks || 321 ticks || 289 ticks float: 315 ticks || 289 ticks || 288 ticks
The code:
#include <stdio.h> #include <time.h> int main () { double start,end; double dif; double i; // Change the type for the J variable to get the variations i got float j=0; start = clock(); for (i = 0; i < 100000000; i++) { j++; } end = clock(); dif = end - start; printf("It took %.f ticks / %d s.\n", dif , CLOCKS_PER_SEC ); return 0; }
