GetTickCount
The GetTickCount() function returns the number of milliseconds that elapsed since the system start.
Return Value
Note
Example:
#define MAX_SIZE 40
//+------------------------------------------------------------------+
//| Script for measuring computation time of 40 Fibonacci numbers |
//+------------------------------------------------------------------+
void OnStart()
{
//--- Remember the initial value
uint start=GetTickCount();
//--- A variable for getting the next number in the Fibonacci series
long fib=0;
//--- In loop calculate the specified amount of numbers from Fibonacci series
for(int i=0;i<MAX_SIZE;i++) fib=TestFibo(i);
//--- Get the spent time in milliseconds
uint time=GetTickCount()-start;
//--- Output a message to the Experts journal
PrintFormat("Calculating %d first Fibonacci numbers took %d ms",MAX_SIZE,time);
//--- Script completed
return;
}
//+------------------------------------------------------------------+
//| Function for getting Fibonacci number by its serial number |
//+------------------------------------------------------------------+
long TestFibo(long n)
{
//--- The first member of the Fibonacci series
if(n<2) return(1);
//--- All other members are calculated by the following formula
return(TestFibo(n-2)+TestFibo(n-1));
