C Exercises: Calculate the total, percentage and division to take marks of three subjects

C Conditional Statement: Exercise-12 with Solution

Write a C program to read roll no, name and marks of three subjects and calculate the total, percentage and division.

Sample Solution:

C Code:

#include <stdio.h>
#include <string.h>

void main()
{
    int rl,phy,che,ca,total;
    float per;
    char nm[20],div[10];
    printf("Input the Roll Number of the student :");
    scanf("%d",&rl);
    printf("Input the Name of the Student :");
    scanf("%s",nm);
    printf("Input  the marks of Physics, Chemistry and Computer Application : ");
    scanf("%d%d%d",&phy,&che,&ca);
    total = phy+che+ca;
    per = total/3.0;
    if (per>=60)
	 strcpy(div,"First");
    else
	if (per<60&&per>=48)
	    strcpy(div,"Second");
	else
	    if (per<48&&per>=36)
		strcpy(div,"Pass");
	     else
		strcpy(div,"Fail");

       printf("\nRoll No : %d\nName of Student : %s\n",rl,nm);
       printf("Marks in Physics : %d\nMarks in Chemistry : %d\nMarks in Computer Application : %d\n",phy,che,ca);
       printf("Total Marks = %d\nPercentage = %5.2f\nDivision = %s\n",total,per,div);
}

Sample Output:

Input the Roll Number of the student :784                                                                     
Input the Name of the Student :James                                                                          
Input  the marks of Physics, Chemistry and Computer Application : 70 80 90                                    
                                                                                                              
Roll No : 784                                                                                                 
Name of Student : James                                                                                       
Marks in Physics : 70                                                                                         
Marks in Chemistry : 80                                                                                       
Marks in Computer Application : 90                                                                            
Total Marks = 240                                                                                             
Percentage = 80.00                                                                                            
Division = First
