}
Output:
Enter marks for 6 subjects (out of 100 each):
Enter marks of Hindi: 85
Enter marks of English: 92
Enter marks of Mathematics: 78
Enter marks of Science: 89
Enter marks of Social Studies: 91
Enter marks of Computer Science: 84
Total marks obtained: 529 out of 600
Here’s a step-by-step explanation of the code:
1. Header and Namespace:
- #include <iostream>: This line includes the iostream header file, which provides input and output functionalities like cin and cout.
- using namespace std;: This line brings the std namespace into scope, allowing you to use elements like cin and cout without the std:: prefix.
2. Main Function:
- int main(): This line defines the main function, where program execution begins.
3. Variable Declaration:
- int sub1, sub2, …, total;: These lines declare integer variables to store marks for each subject (sub1 to sub6) and the total marks.
4. User Input:
- cout << “Enter marks for 6 subjects…\n”;: This line prompts the user to enter marks.
- cin >> sub1;: This line takes input for the first subject’s marks and stores it in the variable sub1.
- … (similar lines for other subjects): The code continues to prompt and take input for the remaining subjects.
5. Calculation:
- total = sub1 + sub2 + … + sub6;: This line calculates the total marks by adding the marks of all subjects and storing the result in the total variable.
6. Output:
- cout << “\nTotal marks obtained: ” << total << ” out of 600\n”;: This line displays the calculated total marks to the user.
7. Return Statement:return 0;: This line indicates successful program termination.
