Ques:-7) The marks obtained by a student in 5 different subjects are input through the keyboard. The student gets a division as per the following rules:
Percentage above or equal to 75 – Honors
Percentage above or equal to 60 – First Division
Percentage between 50 and 59 – Second Division
Percentage between 40 and 49 – Third Division
Percentage less than 40 – Fail
Write a program to calculate the division obtained by the student
#include<stdio.h>
#include<conio.h>
void main()
{
int m1,m2,m3,m4,m5,per,total;
clrscr();
printf("Enter the marks obtained by a student in 5 different subjects\n");
scanf("%d%d%d%d%d",&m1,&m2,&m3,&m4,&m5);
total=m1+m2+m3+m4+m5;
printf("total marks obtained is:%d\n",total);
per=total/5;
printf("Percentage obtained is:%d\n",per);
if(per<40)
printf("fail\n");
if(per>=40&&per<=49)
printf("Third division\n");
if(per>=50&&per<=59)
printf("Second division\n");
if(per>=60&&per<75)
printf("First division\n");
if(per>=75)
printf("Honors");
getch();
}
Out Put
Another program
#include <stdio.h>
int main() {
float marks[5];
float total = 0;
float percentage;
int i;
// Input marks for 5 subjects
printf("Enter the marks obtained in 5 subjects: \n");
for (i = 0; i < 5; i++) {
printf("Subject %d: ", i + 1);
scanf("%f", &marks[i]);
total += marks[i];
}
// Calculate percentage
percentage = (total / 500) * 100;
// Determine division based on percentage
printf("Total Marks = %.2f\n", total);
printf("Percentage = %.2f%%\n", percentage);
if (percentage >= 75) {
printf("Division: Honors\n");
} else if (percentage >= 60) {
printf("Division: First Division\n");
} else if (percentage >= 50) {
printf("Division: Second Division\n");
} else if (percentage >= 40) {
printf("Division: Third Division\n");
} else {
printf("Division: Fail\n");
}
return 0;
}
Explanation:
Variable Declaration:
marks[5]to store the marks of 5 subjects.totalto store the sum of all marks.percentageto store the calculated percentage.ifor the loop index.
Input Marks:
- A loop is used to take input for the 5 subjects and simultaneously sum them up into the
total.
- A loop is used to take input for the 5 subjects and simultaneously sum them up into the
Calculate Percentage:
- The percentage is calculated by dividing the
totalby 500 (since there are 5 subjects, and each subject is assumed to be out of 100) and then multiplying by 100.
- The percentage is calculated by dividing the
Determine Division:
- Based on the percentage calculated, the program prints the division according to the given rules.
This program will take the marks of 5 subjects from the user, calculate the total and percentage, and then determine and print the division the student falls into.
