Switch in C+

[Cassady]

Hey everybody!

I couldnt use the switch in C++.
My study code is:

#include <iostream>
using std::cout;
using std::cin;
using std::endl;

int main(){
    int a; 
    cin >> a;
    
           switch (a) {
                  case '1':
                  cout << "111";           
                  break;
                  
                  case '2':
                  cout << "222";                  
                  break;
                  
                  case '3':
                  cout << "333";                 
                  break;
                  
                  default:
                  cout << "Incorrect";

                  break;
           }
   
 system("PAUSE");
 return EXIT_SUCCESS;

Where the error in my code? How can I fix it?

Thanks!

'1' is a char whose value in ASCII is 49. a is an int, so unless you enter 49 as the input, you are unlikely to get "111" printed. In short, change '1' to 1, '2' to 2, and '3' to 3.

Thanks!
I understood now.

Or change the variable a to be of char type.
