2. Show candidate list

3. Search candidate

Answer 1

#include <iostream>
#include <queue>

using namespace std;

struct Candidate {
  string name;
  int category;
  bool register_no;
  int age;
};

queue<Candidate> que;

void register() 
{
  struct Candidate c;
  cout << "Name: "; cin >> c->name;
  cout << "Category: "; cin >> c->category;
  cout << "Register no: "; cin >> c->register_no;
  cout << "Age: "; cin >> c->age;
  que.push_back(c);
}

void show(struct Candidate c)
{
  cout << "---";
  cout << c->name << endl;
  cout << c->category << endl;
  cout << c->register_no << endl;
  cout << c->age << endl;
}

struct Candidate search(string name)
{
  for (struct Candidate c : que) {
    if (c->name == name)
      return c;
  }
  return nullptr;
}

int main() 
{
  while (true) {
    cout << "1) Register" << endl;
    cout << "2) Show Candidate List" << endl;
    cout << "3) Search" << endl;
    string name;
    int i; 
    cin >> i;
    switch (i) {
      case 1:
        register();
        break;
      case 2:
        show();
        break;
      case 3:
        cout << "Name: "; cin >> name;
        struct Candidate c = search(name);
        if (c) {
          cout << c->name << endl;
          cout << c->category << endl;
          cout << c->register_no << endl;
          cout << c->age << endl;
        } else {
          cout << "Candidate with name '" << name << "' not exists" << endl;
        }
        break;
      default:
        cout << "Invalid choice" << endl;
        break;
    }
  }  
  return 0;
