Just a few days ago I was working on a encrypting program that would take a character and convert it to the corresponding number. while working on it I found that you could input multiple letters and it would loop through all the letters and I can't figure out why it's not really a problem just trying to figure out what's going on....btw it is set to a loop at the beginning so you can keep entering more sentences to encrypt.

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    char Letter;
    int number;
    cout <<"please type your unencrypted sentence" << endl;
    cout <<"remeber to use commas to space your words" << endl;
    do{
    cin >> Letter;
        if(Letter == ('a')){
             number = 109;
             }
        if(Letter == ('b')){
             number = 100;
             }
        if(Letter == ('c')){
             number = 101;
             }
        if(Letter == ('d')){
             number = 119;
             }
        if(Letter == ('e')){
             number = 111;
             }
        if(Letter == ('f')){
             number = 110;
             }
        if(Letter == ('g')){
             number = 199;
             }
        if(Letter == ('e')){
             number = 190;
             }
        if(Letter == ('h')){
             number = 999;
             }
        if(Letter == ('i')){
             number = 991;
             }
        if(Letter == ('j')){
             number = 990;
             }
        if(Letter == ('k')){
             number = 900;
             }
        if(Letter == ('l')){
             number = 909;
             }
        if(Letter == ('m')){
             number = 901;
             }
        if(Letter == ('n')){
             number = 919;
             }
        if(Letter == ('o')){
             number = 910;
             }
        if(Letter == ('p')){
             number = 911;
             }
        if(Letter == ('q')){
             number = 191;
             }
        if(Letter == ('r')){
             number = 809;
             }
        if(Letter == ('s')){
             number = 800;
             }
        if(Letter == ('t')){
             number = 801;
             }
        if(Letter == ('u')){
             number = 819;
             }
        if(Letter == ('v')){
             number = 810;
             }
        if(Letter == ('w')){
             number = 811;
             }
        if(Letter == ('x')){
             number = 899;
             }
        if(Letter == ('y')){
             number = 890;
             }
        if(Letter == ('z')){
             number = 891;
             }
        if(Letter == (',')){
             number = 980;
             }
        if(Letter == ('.')){
             number = 989;
             }
         
    cout << number << ":";
    }while(number <= 1000);
    getch();
    return 0;
}

LOL I'm stupid .... its because of the loop at the end it's returning back to the top and continuing with the rest of the characters
