Question

4-card poker

Prompt the user, input 4 fixed point values, which can be input in any order.

C&d on input failure.

Each of the 4 numbers is supposed to be in the range [1, 13], otherwise c&d.

Output the appropriate one of the following 5 messages:

4 of a kind

3 of a kind

two pairs

one pair

nothing

For example, if the input were

5 5 1 5

then your program would output

3 of a kind

I don't know what I did wrong in my code and i'm stuck please help

#include<iostream>
#include <cstdlib>
#include <string>
using namespace std;

bool die(const string & msg);

int main() {

   unsigned c0, c1, c2, c3;

   cout << "Please enter 4 cards in[1,13]: ";
   cin >> c0;
   if (!cin) die("Input Failure");
   if (c0 < 1 || c0 > 13)   die("Out Of Range");

   cin >> c1;
   if (!cin) die("Input Failure");
   if (c1 < 1 || c1 > 13)   die("Out Of Range");

   cin >> c2;
   if (!cin) die("Input Failure");
   if (c2 < 1 || c2 > 13)   die("Out Of Range");

   cin >> c3;
   if (!cin) die("Input Failure");
   if (c3 < 1 || c3 > 13)   die("Out Of Range");

   cout << c0 << " " << c1 << " " << c2 << " " << c3 << endl;

   if (c1 == c3)
       cout << "There are 4 of a kind. \n";
   else if (c0 == c1 || c1 == c2 || c2 == c3)
       cout << "There are 3 of a kind. \n";
}

   unsigned pairs(c0 == c1) + (c0 == c2) + (c0; c1)

   switch (pairs) {
   case 0:
       cout << "Nothing!";
       break;
   case 1:
       cout << "There are 4 of a kind. \n";
       break;
  
   case 2:
       cout << "There are 3 of a kind. \n";
       break;

   default: die("ERROR");
   }
}

bool die(const string & msg) {
   cout << "Fatal error : " << msg << endl;
   exit(EXIT_FAILURE);
}

Answer 1

your logic was wrong I corrected the logic, Please give thumbs up, thanks

code:

#include<iostream>
#include <cstdlib>
#include <string>
#include<cmath>
using namespace std;

bool die(const string & msg);

int main() {

unsigned c0, c1, c2, c3;

cout << "Please enter 4 cards in[1,13]: ";
cin >> c0;
if (!cin) die("Input Failure");
if (c0 < 1 || c0 > 13) die("Out Of Range");

cin >> c1;
if (!cin) die("Input Failure");
if (c1 < 1 || c1 > 13) die("Out Of Range");

cin >> c2;
if (!cin) die("Input Failure");
if (c2 < 1 || c2 > 13) die("Out Of Range");

cin >> c3;
if (!cin) die("Input Failure");
if (c3 < 1 || c3 > 13) die("Out Of Range");

cout << c0 << " " << c1 << " " << c2 << " " << c3 << endl;
unsigned pairs=((c0 == c1) + (c0 == c2) + (c0== c3))+((c1 == c0) + (c1 == c2) + (c1== c3))+((c2 == c0) + (c2 == c1) + (c2== c3))+((c3 == c0) + (c3 == c1) + (c3== c2));
int c=ceil((double)pairs/4);
switch (c) {
case 0:
cout << "Nothing!";
break;
case 1:
cout << "There are 2 of a kind. \n";
break;
  
case 2:
cout << "There are 3 of a kind. \n";
break;
case 3:
   cout << "There are 4 of a kind. \n";
break;

default: die("ERROR");
}
}

bool die(const string & msg) {
cout << "Fatal error : " << msg << endl;
exit(EXIT_FAILURE);
}
