This program is a mini-project in C programming written using Dev C++ version 5, you can use any standard C compiler to compile the following program.
To help you understand this program, we have the following sections – problem definition, flowchart, program source code, and verified output.
In this C program, we want to compute the following.
- Students’ total marks
- Compute the cutoff marks
- Check if the students are eligible for engineering or medical admission
- Display ‘P’ for Pass, ‘F’ for Fail, ‘E’ if eligible for engineering, ‘M’ if eligible for medical admission
Problem Definition
This program require some input from the users. The input to the program is student information.
- Name
- Registration
and students mark in following 6 subjects.
- Language 1
- Language 2
- Mathematics
- Physics
- Chemistry
- Biology
One the program receives the input values, it will compute following output.
- Total marks in all subjects
- Average marks in all subjects
- Engineering cutoff marks (Must be greater than or equal to 220 for eligibility)
- Medical cutoff marks (Must be greater than or equal to 230 for eligibility)
- Display ‘P’ if student pass in all subjects (All marks greater than 50)
- Display ‘F’ if student fail in any subject (Mark is less than 50)
- Display ‘E’ if student passed and eligible for Engineering admission
- Display ‘M’ if student passed and eligible for medical admission
Let us see how these outputs are calculated.
Total Marks = (Lang1 + Lang2 + Math + Physics + Chemistry + Biology)
Average Marks = (Lang1 + Lang2 + Math + Physics + Chemistry + Biology)/6
Engineering Cutoff = Math/2+ Physics/4 + Chemistry/4
Medical Cutoff = Math/2 + Biology/4 + Chemistry/4Flowchart of the Program
