C Program to Find Grade of a Student Using If Else statement | The if-else statement in C is a selection statement. When dealing with selection statements, there are generally three versions: one-way, two-way, and multi-way. One way decision statements do a particular thing or they do not. Two-way decision statements can do one thing or do another. Multi-way decision statements can do one of many different things depending on the value of an expression.
Prerequisites for finding grade of a student using if-else statements:-
The below table shows the grading system.
Score in subject | Grade |
>=90 | A |
80-89 | B |
70-79 | C |
60-69 | D |
50-59 | E |
<50 | F |
Program description:- Write a C Program to Find Grade of a Student Using If Else statement.
#include<stdio.h>
int main()
{
// variables
int score;
char grade;
// take score
printf("Enter score(0-100): ");
scanf("%d",&score);
// check score is valid or not
// score is valid if it belongs to 0-100
if(score<0 || score>100) {
printf("Invalid Score");
// stop execution
return 0;
}
// find grade for given score
// for score >= 90
if(score>=90 && score<=100)
grade = 'A';
// for score>=80 and <90
else if(score>=80)
grade = 'B';
// for score>=70 and <80
else if(score>=70)
grade = 'C';
// for score>=60 and <70
else if(score>=60)
grade = 'D';
// for score>=50 and <60
else if(score>=50)
grade = 'E';
// for score<50
else
grade = 'F';
// display grade
printf("Grade: %c\n", grade);
return 0;
}
Output:-
Enter score(0-100): 79
Grade: C
Enter score(0-100): 64
Grade: D
Enter score(0-100): 55
Grade: E
Enter score(0-100): 83
Grade: B
Enter score(0-100): 95
Grade: A
Enter score(0-100): 20
Grade: F
Enter score(0-100): 105
Invalid Score
Enter score(0-100): -15
Invalid Score
In this program, we have declared score and grade variables. The score variables will be used to store input from the end-user and the grade variable will store the grade value after finding the grade using an if-else statement. Then we have taken the input value from the end-user and stored it in the score variable.
Now, checked the entered score is valid or not. If the score doesn’t belong to 0 to 100 (inclusive) then it will be treated as invalid score. In that it will display the appropriate message and stop the execution of the program.
If the score is valid then we will start finding the grade based on the given score. From the table, if the score is greater than or equal to 90 then the grade will ‘A’, and so on. For a score lesser than 50 the grade will be ‘F’. Finally, we displayed the grade value on the screen.
