Simple Grading System Using Turbo-C or C-Language

This Project is develop using Turbo-C, the project compute the semester grade of student  it can identify if the student is Failed or Passed. The coding of said project is using of different programming operators and logical statement like (IF-Else Statement), (Do-While Loop) and etc.


Project Specification
Programming Language Use: Turbo-C
Version: Any Version: Any Version of Turbo-C Console

Here is the Code:
