Thread: Evaluate time in C++

Can you give me a example,plz!! ^.^
I have tried in this code:

int var1,var2,diff;

var1 = CLOCKS_PER_SEC;

ab.saveToFile("ATM.txt",key);

var2= CLOCKS_PER_SEC;

cout << " :" << var2;

diff = var2-var1;

cout << endl<<diff <<endl;

and the result is var1 = 1000;
var 2 =1000
diff = 0 :|

And i can't include clock.h

Thanks!!
