Hai,
This is a source code written in turbo c for car racing game as a part of my higher secondary project.
May I get some advices to improve it?
1.Did I use the real method to constitute motion in c?
2.How can I include sound in c?
{ Function sound() is not working .. I think it is due to absence of speaker in my cabinet.. Can I use other sound functions.}
3.Which is the latest and simple compact C\C++ compailor?
4.Now what is the commercial use of C\C++ language?
5.Which compailor can I use in free Operating systems such as ubuntu,kubuntu, linux?
I expect answer for these question...
