Question

In C++ , given, string words = "OO/CC II/ZZ";

How do you make it so if user inputs Z, you replace of the Z with ' '  and return

words = "OO/CC II/Z ";

and if the user inputs another Z then it returns

words = "OO/CC II/ ";

but if the user inputs Z for the third time, it makes the user re-enter another character and shows a retry message.

Answer 1

Here is the desired output

And here is the C++ Code

#include <iostream>
#include <string>

using namespace std;


int main()
{
  char words[] = "OO/CC II/ZZ", ch, choice;
  int i=0;
  
  J:
   cout<<"Do you want to enter the character Z? Y for YES or N for NO\n";
   cin>>choice;
   
   if((int)choice==(int)'Y')
   {
       cout<<"Enter Z \n";
       cin>>ch;
   }
   
   if((int)ch==(int)'Z')
   {
     i++;  
   }
   
   switch(i)
   {
       case 1: words[10]=' ';
               cout<<words<<endl;
               goto J;
               break;
   
       case 2: words[9]=' ';
               cout<<words<<endl;
               goto J;
               break;
               
       case 3: cout<<"Enter another character other than Z\n";
               cin>>ch;
               
               if(ch!=(int)'Z')
               cout<<"retry again"<<endl;
               else
               cout<<"Don't enter Z again";
               goto J;
               
               
       default: cout<<"Choice not available";
               
    
   }
   
   
   return 0;
}
