making mobile phone snake game using C

[hunkadarsh]

i guess i need real helpp for my mini project at college,please help me executing this problem.
Also thr is an .cpp attachment file used in Turbo C ,
Please help

Many simple syntax error, seems like you're in your first 3 or 6 month of learn in programming... Keep the spirit :)
Thank's to the IDE, all errors and warning can be solved in only few minutes..
But though no more errors and warnings message still i think you need to fix some logic of the program.
Oh, one more thing. Seems like you're writing in C not in C++ so i think it's better to change the file name from Snake.cpp to Snake.c

The code bellow is tested on Borland Turbo C 3.0, and since it's utilizing borland specific graphic library, seems like other compilers will fail to compile this code.
