#include<iostream>

using namespace std;
class Bugs
{
    public:
    int Number;
    int Result;
    char Report;
    void Display();
    void input();

};

void Bugs::input()
{
  cout<<"Enter value forf Bugs \n";
  cin>>Number;
  cout<<"Now, Enter value for results \n";
  cin>>Result;

}

void Bugs::Display()
{
    cout<<"\n you are in DISPLAY \n";
    cout<<"\n\n\n\n\n" <<Number;
    cout<<Result;

}

int main()
{
    
    Bugs c1;
     int A;
    cout<<"You are in main";
    cin>>A;


  /* [color=yellow]Here I am getting error[/color] */ c1.void input();
   /* [color=yellow]Here I am getting error[/color] */c1.void Display();

    cout<<"value for Report \n\n\n";
    cin>>c1.Report;
 cout<<" THis is you entered\t"<<c1.Report;
  cout<<"\n\n\n\n"<<c1.Number<<"\t"<<c1.Result;
 return 0;
}

I am getting two same errors saying: " unqualified-id before 'void' ".

c1.input();

Where do you REALLY expect cin data to come from? Where do you really expect cout data to go to?

Take a good hard look at your Arduino. Do you SEE an input mechanism? Do you see an output mechanism?

Just because the code compiles (or would if you had a clue) does NOT mean that it makes a bit of sense.
