C++ Program to Display Grade of a Student Using Switch Case

Write a C++ Program to Find a Grade of Given Marks Using Switch Case, Take User Input and Print the Grade of a Student, Using an Absolute Grading System. Program in c++ language to find a grade of given marks using switch case. Take input from the user and print the grade of a student of the subject, for this problem use an absolute grading system, not a relative grading system. In the console also print the message with a grade to appreciate a student.

Logic is very simple for grade programs in C++ using a switch case. Taking input from the user(Input should be between the range given 0 to 100. Else program plays with you), as we know the grading system so divides the Mark by 10 and put the case condition in program See the below Explanation Step by step for better understanding.

Grade of a Student Explanation

So first divide the mark by 10 so we can get a reminder and as you can see in the program we use case 4 to case 10. So if the remainder is between 4 to 10 our case performs the particular grade operation and displays the result See the Step By Step Example for each case that may be in this grade problem.

Case 1: If the user is Over smart then there is a condition that if the mark given by the user is greater than 100 then our program displays the message "Don't Be Smart Enter your Marks Between Limit" or else perform the Else part.

Enter the Mark: 1000
Output: Don't Be Smart Enter your Marks Between Limits.

Case 2: If the user is entering the marks between 0 to 100 and then the particular grade portion will be executed and display the output in the Console screen.

Enter the Mark: 95
Output: Your Grade is: A or Excellent

This operation performs the same for grades B, C, and D.

Case 3: If Enter marks are not fulfilled the requirement of the case then the program will perform the default case.

Enter the Mark: 25
Output: Your Grade is: F or Fail
