At first I tried to use clock() function in c to time one single addition in C. But the computer is too fast and all you can get is 0.00000 second. Therefore I wrote a loop to do 1000000000 additions and use the clock() function to find out the total time.

Here is the code I have used...

void main() {

   long time,a=0; 
   time = clock();
   for (int b=0;b<1000000000;b++) 
   { 
       a++; 
   }
   time = (clock() - time);
   printf("%ld \n", time);

}

The results for int, long and short were similar, which were about 2300. The double and float type took longer to calculate, the results were above 8000.
