Letter Identification

Question-> (Letter Identification)


Given three words, write an algorithm and the subsequent C++ code to identify the following letters:

 

1.Letters Common To All The Three Words.

2.Letters In First Two Words But Not In The Third Word.

3.Letters In First Word But Not In Second And Third Word.

4.Letters In All The Three Words.

 

FOR EXAMPLE-If The Words Are Apple, Camel, Element Then L

1.Letters Common To All The Three Words-  l, e

2.Letters In First Two Words But Not In The Third Word- a

3.Letters In First Word But Not In Second And Third Word- p

4.Letters In All The Three Words- a, p, l, e, c, m, n, t;

 

CODE:



#include <iostream>
#include <cstring>
using namespace std;
int main()
{
    string st1 ;
    cin>>st1;
    string st2 ;
    cin>>st2;
    string st3 ;
    cin>>st3;
    int count = 0;
    // case1:
    cout << "Letters Common On all the Three words are= ";
    for (int i = 0; i < st1.size(); i++)

                }

                {
                    cout << st1[i] << " ";
                    break;
                }
            }
        }
    }

    // case 3:

        count = 0;

            {

                {
                    if (st1[i] != st3[k])
                    {
                        count++;
                    }
                }
            }
            count++;
        }
        int size = (st2.size() * st3.size() + st2.size());
        if (count == size)
        {
            cout << st1[i] << " ";
            break;
        }
    }
    cout << endl;
    // case4:

    cout << "Letters in All the three words= ";
    string st4;
    st4 = st4 + st1 + st2 + st3;
    for (int i = 0; i < st4.size(); i++)
    {
        count = 0;
        for (int j = i + 1; j < st4.size(); j++)
        {
            if (st4[i] == st4[j])
                count++;
        }
        if (count == 0)
            cout << st4[i] << " ";
    }
}
