📌 Information & Algorithm

Given Input:

Enter marks obtained in subject 1: 50
Enter marks obtained in subject 2: 60
Enter marks obtained in subject 3: 70
Enter marks obtained in subject 4: 80
Enter marks obtained in subject 5: 90

Expected Output:

Total marks obtained: 350.00
Percentage marks obtained: 70.00

💻 Program Code

#include <stdio.h>

int main()
{
    int marks1, marks2, marks3, marks4, marks5;
    float total, percentage;

    printf("Enter marks obtained in subject 1: ");
    scanf("%d", &marks1);

    printf("Enter marks obtained in subject 2: ");
    scanf("%d", &marks2);

    printf("Enter marks obtained in subject 3: ");
    scanf("%d", &marks3);

    printf("Enter marks obtained in subject 4: ");
    scanf("%d", &marks4);

    printf("Enter marks obtained in subject 5: ");
    scanf("%d", &marks5);

    total = marks1 + marks2 + marks3 + marks4 + marks5;
    percentage = (total/500) * 100;

    printf("Total marks obtained: %.2f\n", total);
    printf("Percentage marks obtained: %.2f\n", percentage);

    return 0;
}

🖥 Program Output

Enter marks obtained in subject 1: 50
Enter marks obtained in subject 2: 60
Enter marks obtained in subject 3: 70
Enter marks obtained in subject 4: 80
Enter marks obtained in subject 5: 90
Total marks obtained: 350.00
Percentage marks obtained: 70.00

📘 Explanation

Start the program by including the standard input/output library
Create variables for marks1, marks2, marks3, marks4, marks5, total, and percentage as integers
Print a message requesting the user to input the marks obtained in subject 1 and store the value in marks1
Print a message requesting the user to input the marks obtained in subject 2 and store the value in marks2
Print a message requesting the user to input the marks obtained in subject 3 and store the value in marks3
Print a message requesting the user to input the marks obtained in subject 4 and store the value in marks4
Print a message requesting the user to input the marks obtained in subject 5 and store the value in marks5
Calculate the total marks obtained by adding all the marks together and store the value in total
Calculate the percentage marks obtained by dividing the total marks by 500 and multiplying by 100 and store the value in percentage
Print the total marks obtained and the percentage marks obtained
End the program

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
