C program to Find Total, Average, and Percentage of Five Subjects

In this article we will show you, How to write a C program to find Total, Average, and Percentage of Five Subjects, or N number of subjects

C program to Find Total, Average, and Percentage of Five Subjects

This C program helps the user to enter five different values for five subjects. And then it will find the Total, Average, and Percentage of those Five Subjects. For this, we are using the Arithmetic Operators to perform arithmetic operations.

/* C program to Find Total, Average, and Percentage of Five Subjects */

#include <stdio.h>

int main()
{
    int english, chemistry, computers, physics, maths; 
    float Total, Average, Percentage;

    printf("Please Enter the marks of five subjects: \n");
    scanf("%d%d%d%d%d", &english, &chemistry, &computers, &physics, &maths);

    Total = english + chemistry + computers + physics + maths;
    Average = Total / 5;
    Percentage = (Total / 500) * 100;

    printf("Total Marks = %.2f\n", Total);
    printf("Average Marks = %.2f\n", Average);
    printf("Marks Percentage = %.2f", Percentage);

    return 0;
}

OUTPUT 

C program to Find Total, Average, and Percentage of Marks

Above program is more of fixed subjects. In this C program user has the flexibility to choose number of subjects. And then, it will find the Total marks, its Average, and percentage

 /* C program to Find Total, Average, and Percentage of Marks */  
#include <stdio.h>  
int main()
{
    int Total_Subjects, i;  
    float Marks, Total, Average, Percentage;
   
    printf("Please enter the Total Number of Subjects\n");  
    scanf("%d", &Total_Subjects);  
   
    printf("Please Enter the Marks for each Subject\n");  
    for(i = 0; i < Total_Subjects; i++)
    {
     scanf("%f", &Marks);
     Total = Total + Marks; 
    }  
    Average = Total / Total_Subjects;
    Percentage = (Total/(Total_Subjects * 100)) * 100;  
   
    printf("Total Marks of %d Subjects = %0.2f\n",Total_Subjects,Total);  
    printf("Average Marks = %.2f\n", Average);  
    printf("Percentage = %.2f", Percentage);  
   
    return 0;  
}

ANALYSIS

1. First printf statement will ask the user to enter the Total number of Subjects. For example if the user enters 3 then, second printf statement will ask the user to enter those 3 values one after the other.
2. For loop will resist the user, not to enter more than 3 values by using the condition i<n. In the next line we are adding the user entered value to Total.
3. Outside the loop we calculated the average, and percentage.
