Answer 1

#include <iostream>
#include <cstring> // Include for string handling
using namespace std;

struct student {
    int exam_no, lang, eng, phy, che, mat, csc, total;
    char name[15];
};

int main() {
    student s[20];

    // Accept student details
    for (int i = 0; i < 20; i++) {
        cout << "\nEnter student name: ";
        cin >> s[i].name;
        cout << "Enter student exam number: ";
        cin >> s[i].exam_no;
        cout << "Enter Language Mark: ";
        cin >> s[i].lang;
        cout << "Enter English Mark: ";
        cin >> s[i].eng;
        cout << "Enter Physics Mark: ";
        cin >> s[i].phy;
        cout << "Enter Chemistry Mark: ";
        cin >> s[i].che;
        cout << "Enter Maths Mark: ";
        cin >> s[i].mat;
        cout << "Enter Computer Science Mark: ";
        cin >> s[i].csc;
        s[i].total = s[i].lang + s[i].eng + s[i].phy + s[i].che + s[i].mat + s[i].csc;
    }

    cout << "\nDetails of students whose name starts with letter S:\n";
    
    // Check for names starting with the letter "S" and display details
    for (int i = 0; i < 20; i++) {
        if (s[i].name[0] == 'S') {
            cout << "\nName: " << s[i].name;
            cout << "\nTotal Marks: " << s[i].total << endl;
        }
    }

    return 0;
}

Output:

Details of students whose name starts with the letter S:

Name: Sam
Total Marks: 488

Name: Steve
Total Marks: 506
