Runtime calculation

[Ken]

Hello

In microsoft Visual c++
Is it possible to calculate the runtime of a function?
If so where do we go to activate it.

Thank you

Please consider posting to 'microsoft.public.vc.language', which
incidentally is the newsgroup for that compiler. Here we talk
standard C++ as a _language_ only, not products or compilers.

????????????????

Do you mean the time spent in a function when executing it?

clock() is an ANSI Std function avail in Stds conforming
implementations.

Here's an example:

#include <iostream>
#include <ctime>

int main( )
{
int x = 100;
long i = 600000L;
clock_t start, finish;
double duration;


// Measure how long to do 600000 loops 100 times.
std::cout << "Time to do " << i << " empty loops "
<< x << " times is " << std::endl;
start = std::clock();
while( x--)
{
while( i--)
continue;
i = 600000L;
}
finish = std::clock();
duration = (double)(finish - start) / CLOCKS_PER_SEC;
std::cout << duration << "seconds" << std::endl;

return 0;
}
