Switch Case question (from C++ Tutorial Example)

Hi,
In working through t the Switch Case example in the C++ tutorial I wanted to try and have the list use characters (a,b,c,d) rather than numbers (1,2,3,4) as the the case identifiers.

Here is the code (in case you forgot:-)

Code:

---

#include <iostream>

using namespace std;

void playgame()
{
    cout << "Play game called";
}
void loadgame()
{
    cout << "Load game called";
}
void playmultiplayer()
{
    cout << "Play multiplayer game called";
}
       
int main()
{
  int input;
 
  cout<<"1. Play game\n";
  cout<<"2. Load game\n";
  cout<<"3. Play multiplayer\n";
  cout<<"4. Exit\n";
  cout<<"Selection: ";
  cin>> input;
  switch ( input ) {
  case 1:            // Note the colon, not a semicolon
    playgame();
    break;
  case 2:            // Note the colon, not a semicolon
    loadgame();
    break;
  case 3:            // Note the colon, not a semicolon
    playmultiplayer();
    break;
  case 4:            // Note the colon, not a semicolon
    cout<<"Thank you for playing!\n";
    break;
  default:            // Note the colon, not a semicolon
    cout<<"Error, bad input, quitting\n";
    break;
  }
  cin.get();
}

I tried changing "input" from int to char with no joy. I also tried just changing the numbers to letters in case with the same predictable results. Is there a library I need to declare or am I on a fools errand?

TIA

Don't show the code you started with. That is not the code causing you problems. Show the code you have actually modified so input is of type char, and then compares input with a,b,c ....

Hint: if you want a switch on the letter 'a', then the relevant case in the switch block looks like

Code:

---

case 'a' :

---

Note the single quotes.

Thanks!
You answered my question. I'd forgotten/didn't know about the single quotes when using chars. I need to get a book in addition to the tutorial it seems.
