C++ Help

shit, i took C++ last year in highschoolmade a program for determining port sizes

all that shit

dice rolling programs for D&D

all that fun shit

and some semi-useful shit

some text based games too

too bad all of it got erased when the school's network got butt****ed over the summer

C++ was fun but its pretty much a dead coding language

alot of highschools dont even teach it anymore

learn java

Dead.

LMAO, you don't know WTF you are talking about tard.

C++ was fun but its pretty much a dead coding language

learn java

no sir, it will never die. Too useful.

 

[lilmaniac2 5,000+ posts]

Just because java is prettier dont mean its better //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

c++ is the driving force for pretty much everything

i also know pascal, now thats a dead language

 

[MemphisCherokee 10+ year member]

i guess when i said dead, i meant, there are alot more languages that are "prettier" anymore

 

[Hundreth 10+ year member]

I'd have to say C is pretty much the driving force for everything, not so much C++... def not a dead language by any means though.

shit, i took C++ last year in highschoolmade a program for determining port sizes

all that shit

dice rolling programs for D&D

and some semi-useful shit

some text based games too

too bad all of it got erased when the school's network got butt****ed over the summer

My *** c++ is dead... every university is going to teach you either Jave or C++ as your core language. Don' talk till you get to college noob or get into the industry.
