BASIC C++ Switch

Question

How make this in the correct way ?

void intro_duels(int x)
{ switch(x)
{
case 1-10:cout<< "text"<<endl;break;
case 11-20:cout<< "text?"<<endl;break;
case 21-49:cout<< " text"<<endl; break;
case 50-99: cout<< "text" << endl; break;
case 100: cout<<"text"<<endl; break;
return ;
}
}

Also how return that "text" and no int to the main function ????

Answer 1

switch cannot check ranges. Use if/else for these. Ex:
if (x >= 1&& x <= 10)
cout << "text" << endl;
else if (x >=11 && x <= 20)
//follow this pattern

To make intro_duels() return the text instead of print it, write the top like this:
string intro_duels(int x)
And make sure
#include <string> //Allows you to use string datatype
is at the top of your code.
Replace your cout statements with
return "text";

To call it, write something like this:
string result = intro_duels(num); //Store it
cout << intro_duels(num); //Print it immediately

Answer 2

you better use the if statment for this
