C program to find the grade of a student; Through this tutorial, we will learn how to find the grade of a student in c program.
C Program to Find Grade of a Student Using If Else
#include <stdio.h>
int main()
{
float marks, Total, Percentage;
printf(" Please Enter Marks out of 500 :-" );
scanf("%f", &marks);
Percentage = (marks / 500) * 100;
printf(" Total Marks = %.2f\n", marks);
printf(" Marks Percentage = %.2f", Percentage);
if(Percentage >= 90)
{
printf("\n Grade A");
}
else if(Percentage >= 80)
{
printf("\n Grade B");
}
else if(Percentage >= 70)
{
printf("\n Grade C");
}
else if(Percentage >= 60)
{
printf("\n Grade D");
}
else if(Percentage >= 40)
{
printf("\n Grade E");
}
else
{
printf("\n Fail");
}
return 0;
}
The output of the above c program; as follows:
Please Enter Marks out of 500 :-435 Total Marks = 435.00 Marks Percentage = 87.00 Grade
C program to find grade of a student using switch case statement
#include<stdio.h>
int main()
{
int score;
printf("Enter score( 0-100 ): ");
scanf("%d", &score);
switch( score / 10 )
{
case 10:
case 9:
printf("Grade: A");
break;
case 8:
printf("Grade: B");
break;
case 7:
printf("Grade: C");
break;
case 6:
printf("Grade: D");
break;
case 5:
printf("Grade: E");
break;
default:
printf("Grade: F");
break;
}
return 0;
}
The output of the above c program; as follows:
Enter score( 0-100 ): 80 Grade: B
