    In the future, you need to explain what your problem is. Does the code compile? Is there an error or warning message you can't fix? Copy-paste the error message(s) exactly so we can help. If the program compiles, does it crash when you run it? Do you get no output? Do you get the wrong output? Tell us the input you provided, the output you expect and the output you actually get.

    In this case, you have a simple syntax error:
    Code:
    $ gcc -Wall -g -std=c99  sale.c   -o sale
    sale.c: In function ‘main’:
    sale.c:6: warning: implicit declaration of function ‘printf’
    sale.c:6: warning: incompatible implicit declaration of built-in function ‘printf’
    sale.c:7: warning: implicit declaration of function ‘scanf’
    sale.c:7: warning: incompatible implicit declaration of built-in function ‘scanf’
    sale.c:7:25: warning: missing terminating " character
    sale.c:7: error: missing terminating " character
    sale.c:8: error: expected ‘)’ before ‘p’
    sale.c:25: error: expected ‘;’ before ‘}’ token
    sale.c:5: warning: unused variable ‘l’
    sale.c:5: warning: unused variable ‘p’
    make: *** [sale] Error 1
    1. The "implicit declaration" messages mean you need to #include <stdio.h>.
    2. The "missing termination" message means you have an erroneous " floating around on line 7. Remove it. This error would be much easier to see if you had an editor with syntax highlighting. There are dozens of free ones available, so look into it. It's a simple but highly effective tool.

    > where cp= cost price , sp= selling price , l= loss , p = profit ,,
    Here's an idea - use those names in the code, instead of being all cryptic and then having to explain yourself.

    I mean
    profit = salePrice - costPrice;
    is a hell of a lot more readable, and needs no afterthough comment, to understand what is going on.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
