EDIT: fixed. the problem lied in the lines like
switch ('entry1')
they were supposed to be
switch (entry1)
for the upper/lowercase issue, I just did a case in the switch statement for every letter . However, I know there is a faster way, and I'm just curious.. does anyone know?


OK, so I'm taking C++ in college, the goal is to write a very simple rock paper scissors game. It's designed for 2 users, and it doesnt matter that user2 can see user1's entry.
first User 1 input's either p, or P, which is for paper. or r, R, s, S...
User 2 does the same.
then, with a nested switch statement, the program says who wins.

here is what I wrote. I added a default case for each switch statement, for invalid entries (i.e. "rock", or "g") that should print that the entry's invalid.
also, the program needs to loop: it should ask after the "game" if the users wanna have another round. That I think I can do, but I haven't bothered writing it yet.
Here's the problem. the program compiles fine but when I enter any supposedly valid entry, the program doesnt work. I tried entering the letters, r, and p and s, like these examples
entry1 == r;
entry1 == 'r";
in upper and lower case. it gives me an invalid entry. (Also I haven't quite done the upper/lowercase equivalence thing yet, I haven't figured out how to do that in a switch statement.

Please help me! I'm fairly new to all this, so if you could try and run the program on your compiler (I use CodeBlocks) and tell me what's wrong or missing, I would greatly appreciate it. Thanks a lot.

Program: now edited, and apparently working (although not written the way I'd like it to be):

#include <iostream>
using namespace std;

int main ()
{
char entry1, entry2, r, p, s;


cout << "User 1, please enter \"p\" for Paper, \"r\" for Rock, or \"s\" for Scissors. \n";
cout << "You may also enter uppercase letters. \n";

cin >> entry1;
switch (entry1)
{
case ('r'):
entry1 == r;
break;

case ('p'):
entry1 == p;
break;

case ('s'):
entry1 == s;
break;

default:
cout << "invalid entry\n";
}

cout << "User 2, please enter \"p\" for Paper, \"r\" for Rock, or \"s\" for Scissors. \n";
cout << "You may also enter uppercase letters. \n";
cin >> entry2;
switch (entry2)
{
case ('r'):
entry2 == r;
break;

case ('p'):
entry2 == p;
break;

case ('s'):
entry2 == s;
break;

default:
cout << "invalid entry\n";
}

switch ('entry1')
{
case ('r'):
switch ('entry2')
{
case ('r'):
cout << "Nobody wins! \n";
break;
case ('p'):
cout << "Paper covers Rock, User 2 wins! \n";
break;
case ('s'):
cout << "Rock crushes Scissors, User 1 wins! \n";
break;
default:
cout << "invalid entry: acceptable entries are \"p\", \"r\", \"s\" in booth lower and upercase.";
break;

}
break;

case ('p'):
switch ('entry2')
{
case ('r'):
cout << "Paper covers rock, User 1 wins! \n";
break;
case ('p'):
cout << "Nobody wins! \n";
break;
case ('s'):
cout << "Scissors cut paper, User 1 wins! \n";
break;
default:
cout << "invalid entry: acceptable entries are \"p\", \"r\", \"s\" in booth lower and upercase.";
break;

}
break;

case ('s'):
switch ('entry2')
{
case ('r'):
cout << "Rock crushes Scissors, User 2 wins! \n";
break;
case ('p'):
cout << "Scissors cut paper, User 1 wins! \n";
break;
case ('s'):
cout << "Nobody wins! \n";
break;
default:
cout << "invalid entry: acceptable entries are \"p\", \"r\", \"s\" in booth lower and upercase.";
break;
}
break;
default:
cout << "invalid entry: acceptable entries are \"p\", \"r\", \"s\" in booth lower and upercase.";
break;


}



return 0;
}



and yes, we are required to write the program in this kind of style (well, only it's also supposed to work ) .
I think I'm also allowed to use if- else statements, but I don't think they'd be as effective. I'd rather stick with switch.
