C++ Optimization

[Zxenke]

Before I post my code, is there anyone who is familiar with C++ enough to help me with optimization of performance of a Windows utility program I wrote?

[phantomlink]

C++ is an evil... evil bitch

[Zxenke]

very true, though it does have some advantages

Points of interest:
*****printf() vs cout vs ostream
*****clock()

erm bro i had bumped a topic in tech for about a month on CSS for websites (probably the easiest form of CSS) and no one even replied to it, you're not going to find help on here, especially in these forums. I'd suggest http://gruntville.com/phpBB2/ my cousin is a part of those guys and they do coding for stanford and stuff, really intelligent people.

How do you people understand how to do this stuff? I went on the website and looked at the tutorial and it looked pretty confusing. Is there classes to learn this stuff other then college courses?

it's pretty easy shit, except i left all the java and stuff cause i wasn't even going into programming, went into biomedical

then answer his question.

I would if I continued taking the course, but I didn't, so only 2 years of learning it isn't enough I guess.

never had C++; i can understand the basic stuff because we get lots of java, php, vb.net etc.

but when i read your code i get confused :unsure:

[Speed]

ive had C, and java and others but not C++ i was assumming it would be the same as C but.. no

and yeah i get confused with ur code too lol

[Zxenke]

Confusing how? Lol

Granted it is written to take the least amount of time, so the verbose forms are not there.

[Speed]

i get the basics of the code lol , its almost same as C

main problem would be, i dont know what the hell that program does XD... or what do you want it to do haha

[Zxenke]

Changed the printf to cout, since printf is solely C, and to keep with coding standard to not mix C and C++.

The point of the program is to display the time of execution of whatever parameter commands given to it.
