if you can wait until thursday, thats when i get home, i can get it and run it for you.

 

the computer just stared back at me and said...

 

i need it today, im going to school in a few hours to run it i got class at 5pm

 

Ummm, how can you take c++ and not have a c compiler?!

 

maybe he is just taking the class at school and didnt want to pay $100 for a verision of c++?

school has a compiler,



I dont have a computer my computer burnt to the ground im using my girls computer. Plus im doing civil engineering but this CE class we have to use C++ to solve CE problems

 

I had a similar problem. Project was due after spring break, I had the project done but no compiler. Emailed the instructor, got a link to Borland to use the free 90-day trial of their compiler, and they emailed me the wrong serial number and passcode! 3 TIMES! I couldn't do any of the work at home, and had no time to go to school during the computer lab's open hours... ended up having to drop the class.
