#include
using namespace std;

int main( )
{
    char c;

    cout << "Enter a character ";
    cin >> c;

     if(isalpha(c))
    { //check to see if it is a letter of alphabet
        if( isupper(c) ) //check to see if it is uppercase
        {
            c = tolower(c);
            cout << "Your character " << c << " is in uppercase.";
            cout << "Its lowercase case is " << c << endl;
        }
        else
       {
            c = toupper(c);
            cout << "Your character " << c << " is in lowercase.";
            cout << "Its uppercase is " << c << endl;
