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;
}
