loop iterations

Comment:
Have anyone wondered how many iterations can a forloop run in a second? It does a simple task like:
for(int i = 0; i < some_value; i++) printf("%d ", i);

Time It. Put a GeTickCount API at the beginning. Store the value. Get another one at the end and calculate the difference. The answer is in Milli seconds but will only have an resolution of 15 Milli seconds.
GetTickCount returns the number of milli seconds since the computer was started.
Public Declare Function GetTickCount Lib "kernel32" Alias "GetTickCount" () As Long
