A focused, in-memory approach that satisfies the "structures + functions, no files" constraint and implements admin/user flows is shown below. The snippet is a compact, runnable skeleton: it uses a Question struct, a std::vector to hold questions, separate functions for add/remove/modify/search, and switch-case menus for admin/user. Because data is kept only in memory, the question bank will be lost when the program exits — persistence can be added later if allowed.

#include <iostream>
#include <vector>
#include <string>
#include <cstdlib>
#include <cctype>

struct Question {
    std::string text;
    std::vector<std::string> options;
    int correct; // 0-based index
};

std::string toLower(const std::string &s) {
    std::string r = s;
    for (size_t i = 0; i < r.size(); ++i) r[i] = std::tolower((unsigned char)r[i]);
    return r;
}

int readInt() {
    std::string line;
    std::getline(std::cin, line);
    return std::atoi(line.c_str());
}

void listQuestions(const std::vector<Question> &bank) {
    for (size_t i = 0; i < bank.size(); ++i)
        std::cout << (i+1) << ") " << bank[i].text << "\n";
}

void addQuestion(std::vector<Question> &bank) {
    Question q;
    std::cout << "Enter question:\n";
    std::getline(std::cin, q.text);
    q.options.resize(4);
    for (int i = 0; i < 4; ++i) {
        std::cout << "Option " << (i+1) << ": ";
        std::getline(std::cin, q.options[i]);
    }
    std::cout << "Correct option number (1-4): ";
    q.correct = readInt() - 1;
    if (q.correct < 0 || q.correct > 3) q.correct = 0;
    bank.push_back(q);
}

void removeQuestion(std::vector<Question> &bank) {
    if (bank.empty()) { std::cout << "No questions.\n"; return; }
    listQuestions(bank);
    std::cout << "Enter number to remove: ";
    int idx = readInt() - 1;

    }
    std::cout << "Correct option number (1-4, 0 to keep): ";
    int c = readInt();
    if (c >= 1 && c <= 4) q.correct = c - 1;
}

            std::cout << " " << (j+1) << ". " << q.options[j] << "\n";
        std::cout << "Your answer: ";

    }

int main() {

    for (;;) {
        std::cout << "Main - 1)admin 2)user 3)exit\nChoice: ";
        int ch = readInt();
        if (ch == 1) adminMenu(bank);
        else if (ch == 2) userMenu(bank);
        else if (ch == 3) break;
    }
    return 0;
}

Notes and quick troubleshooting:

  • Use std::getline everywhere to avoid input mixing; numeric input is parsed with atoi for simplicity.
  • Removing uses vector::erase, which shifts subsequent items; present indexes to the admin before delete.
  • Modifying accepts a blank line to keep the current value, which makes small edits easier.
  • Search shown is case-insensitive substring matching.
  • Because the program keeps data in memory only, add a few sample questions in code during testing or add simple import/export later if persistence is permitted.

Context: the OP () said the admin section was the sticking point; this skeleton isolates that area. As and suggested, it is small enough to compile and iterate on so any specific compile errors or runtime behavior can be diagnosed from the concrete code rather than vague descriptions.

Would you like anything else doing ? Cup of tea? Clean your room? Massage?

Is this the approach you take to everything, that someone else can do it for you?

How about you show us how far you have got on your own so far, and where you are getting stuck? How about you then ask for specific help with that part of your assignment, wthout demanding it by a set date?

I'm happy to write you a program that you can compile and run. It will compile and run with no errors. I want no money for this. This is your lucky day since you need not put any effort into this at all. In fact, it works best if you don't look at the code at all and don't try to figure out how it works.

Please note this program will only work if you run it as Admin/root, plus it needs to download a few things so turn off your firewall. And we don't want anyone else in on this. The rest of the class needs to struggle with their own homework, but clearly you're special, so I'm going to give this to you and only you, but you need to promise that you'll only run it on your computer. We don't want anyone else stealing your A+. Deal?

Heh heh.

PS - This doesn't violate Daniweb's anti-malware rule, does it? Err I mean this doesn't violate Daniweb's "No help without effort" rule, does it?

IM SORRY HAPPYGREEK

ACTUALLY IM NOT ABLE TO DO THE ADMIN MENU PART FULL

ACTUALLY MY TEACHER WANT ME TO USE STRUCTURES,AND FUNCTIONS WITHOUT USING FILES

Edited by Reverend Jim because: Please read the rules.

WHY ARE YOU YELLING?

Member Avatar for David W

It is now past 17:30 EST ... and you will need to ask for an extension if you still need help with your school project ...

In the future ...

if you wish help at this very willing to help, help site,

please firstly supply us with the code you have tried already ...

and indicate where you are having issues ...

and we will then see what we might do to help you on your way.

Shalom shalom,
