Write a C Program to Find Grade of a Student Using Switch Case

Write a C Program to Find Grade of a Student Using Switch Case, The user needs to enter the subject number and the program must return the Grade of the subject based on the number. If a student enters a number between 90 to 100 then our program must return the Grade A or Excellent, similarly for other ranges numbers. To get the help I have a Number grade conversion table this may help you to find the proper logic and roadmap for our program to Calculate Grade Using Switch Statement in C.

Logic: Grade of a Student Using Switch Case in C

 
Logic is very simple to Calculate Grade Using Switch Statement in C. Taking input from the user(Input should be between range given 0 to 100 Else program play with you), as we know the grading system so divides the Mark by 10 and put the case condition in the program See the below Explanation Step by step for better understanding.

Number to Student Grade Conversion Table

Below is the number to Grade Conversion Table that helps us to implement the logic for the C Program to Find Grade of a Student Using Switch Case.

Switch Case Grade Program in C 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(Switch Case Grade Program in C) problem.

Grade Program Example

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 part of the program will be performed.

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

Now perform the same operation for Grades B, C, D, E, E-- and F. and write a C Program to Find Grade of a Student Using Switch Case.

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

Required Knowledge: Format Specifiers, Switch Case.

C Program to Find Grade of a Student Using Switch Case

#include<stdio.h>

int main()
{
   int marks;
   /*C Program to Find Grade of a Student Using Switch Case*/
   
   printf("\n-----------------------------------");
   printf("\nEnter The Marks Between 0 To 100:");
   
   printf("\nEnter The Mark: ");
   scanf("%d", &marks);
   
   if(marks>100)
   {
    /* Marks greater than 100 */
    printf("\nDon't Be Smart Enter your Marks Between Limit\n");
   }
   else
   {
   switch(marks/10)
   {
       case 10 :
       case 9 :
           /* Marks between 90-100 */
           printf("\n Your Grade is: A");
           break;
       case 8 :
            /* Marks between 80-89 */
           printf("\n Your Grade is: B" );
           break;
       case 7 :
           /* Marks between 70-79 */
           printf("\n Your Grade is: C" );
           break;
       case 6 :
           /* Marks between 60-69 */
           printf("\n Your Grade is: D" );
           break;
       case 5 :
            /* Marks between 50-59 */
           printf("\n Your Grade is: E" );
           break;
       case 4 :
           /* Marks between 40-59 */
           printf("\n Your Grade is: E--");
           break;
       default :
           /* Marks less than 40 */
           printf("\n You Grade is: F or Fail\n");
   }
 }

   getch();
   return 0;
