Question

C++ coding

Create a class called NumberList that holds a user-defined maximum number of integers in a vector. If more than the maximum number of integers is added an error message should be printed out. Write a method print_list that prints the numberof integers in the list and each number stored in the list. Create at least 2 NumberList objects, fill them, and print their contents. Include your NumberList class and print_list method below along with sample output. You should use good C++ object-oriented design principles, including using a separate .cpp & .h file for defining NumberList.

Explanation / Answer

#include <iostream>
#include <vector>
using namespace std;

class NumberList
{
protected:
vector<int> vec; // create a vector to store int
int max_val,val;

public:

NumberList(){}

void getmaxval()
{
    cout << "Enter the size of vector "; //taking vector limit
    cin>>max_val;
}

output:

void getvectinp()
{
    cout << "Enter the values of vector ";
   for(int i = 0; i < max_val; i++) // push the values into the vector
   {
      cin>>val;
      vec.push_back(val);
   }
}

void insertinp()
{
    if (max_val<=vec.size())     //checking the limit of vector
        cout <<"1"<< "current vector size = " << vec.size() <<" has reached the limit";
    else if(max_val>vec.size())
         getvectinp();
       
}

void disp()
{
    for(int i = 0; i < max_val; i++) // display the values from the vector
    {
      cout << "values of vector [" << i << "] = " << vec[i]<<endl;
    }
    cout << " ";
}
};

int main()
{
NumberList ob1,ob2;

u_chc_lbl:
         ob1.getmaxval();
         ob1.insertinp();
      
         ob2.getmaxval();
         ob2.insertinp();
       
         cout << " For object ob1 ";
         ob1.disp();
         cout << " For object ob2 ";
         ob2.disp();

   cout << "Press any number from 1 to 9 to continue or 0(zero) for exit ";
   int chc;
   cin>>chc;
   if (chc>=1 && chc<=9)
      goto u_chc_lbl;

   return 0;
}
