Question

Write a program and ask a user to enter a numeric value between 0 - 99. Your program will spell out the numbers into words. You must use at least three switch cases in addition to multiple if statements. Each missing switch statement will reduce your grade for this problem by 20%. Note: The total number of if statements and switch cases should not exceed 28. Additional if/case statement will further reduce your grade by 5%.

in c++ please

#include<iostream>
using namespace std;
int main()
{
        int num,tens_digit=-1,units_digit=-1;//decalring variables for number ,stroing unita and tens digit of number
        string units="",tens="";//strings for units and tens digit
        cout<<"Enter the number from 0 - 99"<<endl;
        cin>>num;//reading number
        units_digit=num%10;//retrieving units digit of the number
        num=num/10;
        tens_digit=num%10;
        //retrieving units digit of the number
        if(tens_digit==1 )//(1st if)if the number is between 10 to 19 this if condition is true.
        {
        switch(units_digit)//(contains 10  cases 10+1 if = 11)
                 {
