Calculating Your 5 subjects Percentage in C language code here

#include <stdio.h>

int main() {

    // Variables to store marks

    float subject1, subject2, subject3, subject4, subject5;

    // Input marks for each subject

    printf("Enter marks for Subject 1: ");

    scanf("%f", &subject1);

    printf("Enter marks for Subject 2: ");

    scanf("%f", &subject2);

    printf("Enter marks for Subject 3: ");

    scanf("%f", &subject3);

    printf("Enter marks for Subject 4: ");

    scanf("%f", &subject4);

    printf("Enter marks for Subject 5: ");

    scanf("%f", &subject5);

    // Calculate percentage

    float totalMarks = subject1 + subject2 + subject3 + subject4 + subject5;

    float percentage = (totalMarks / 500) * 100;

    // Display the result

    printf("\nTotal Marks: %.2f\n", totalMarks);

    printf("Percentage: %.2f%%\n", percentage);

    return 0;

}

Step 1: Include Header File

#include <stdio.h>

This line includes the standard input-output header file, which is necessary for using functions like printf and scanf.

Step 2: Declare Variables

float subject1, subject2, subject3, subject4, subject5;

Here, we declare five float variables to store the marks for each subject.

Step 3: Input Marks

printf("Enter marks for Subject 1: ");

scanf("%f", &subject1);

// Repeat for subjects 2 to 5

These lines prompt the user to input marks for each subject, and scanf is used to store the input in the respective variables.

Step 4: Calculate Total Marks

float totalMarks = subject1 + subject2 + subject3 + subject4 + subject5;

This line calculates the total marks by adding the marks of all five subjects.

Step 5: Calculate Percentage

float percentage = (totalMarks / 500) * 100;

This line calculates the percentage based on the total marks obtained out of 500.

Step 6: Display Result

printf("\nTotal Marks: %.2f\n", totalMarks);

printf("Percentage: %.2f%%\n", percentage);

These lines display the total marks and percentage with two decimal places using printf.

Step 7: Return 0

return 0;

This line signifies the end of the program and returns 0 to the operating system, indicating successful execution.

This program takes input for marks in five subjects, calculates the total marks and percentage, and then displays the results.
