Q:

time consumed by win32 console

I have written my code in c++2012 in windows 7 with win32 and console for seeing the result of my program. Because my program must be competitive by passing the time (time is being measured for every step of solution), I think that in console some extra time is consumed to write the output data.
My question is that: Is my proposition true and if true how do I change my c++ project type ?

A:

Yes, writing the output on the console can significantly impact performance. However, simply changing console output to file output should do the trick; the fact that the console appears on the screen is irrelevant, so changing project type is unnecessary.

A:

It is true that concole writing takes comparatively long time. 
But why do you want to change your project type?
Just write the data to some file, like:
your_prog >results.txt

Then the output goes to results.txt and can be viewed later.
