morse code convertor

I'm having troubles getting this converter to work. The getline doesn't seem to work. It skips it and goes right to the end for some reason.

Code:

#include <iostream>
#include <cstring>
using namespace std;
char *morse[36] = { ".-", "-...", "-.-.", "-..", ".", "..-.", "--.", "....",
                    "..", ".---", "-.-", ".-..", "--", "-.", "---", ".--.",
                    "--.-", ".-.", "...", "-", "..-", "...-", ".--", "-..-",
                    "-.--", "--..",
                    
                    "-----", ".----", "..---", "...--", "....-", ".....",
                    "-....", "--...", "---..", "----." };
int main()
{
    int choice = 0;
    while ((choice != 1) && (choice != 2))
    {
        cout << "Enter a choice:" << endl;
        cout << "1. Text-to-Morse" << endl;
        cout << "2. Morse-to-Text" << endl;
        cin >> choice;
    }
    if (choice == 1)
    {
        cout << "Enter a sentence (MAX = 80 chars):" << endl;
        char sentence[81];
        cin.get(sentence, 81);
        for (int i=0; i<=80; i++)
        {
            int mov = 0;
            sentence[i] = toupper(sentence[i]);
            if ((sentence[i] <= 90) && (sentence[i] >= 65))
                mov = 65;
            if ((sentence[i] <= 57) && (sentence[i] >= 22))
                mov = 48;
            if (sentence[i] == 32)
            {
                cout << "   ";
            }
            else { cout << morse[sentence[i]-mov] << " "; }
        }
    }
    if (choice == 2)
    {
        cout << "Enter a sentence in morse (MAX = 80 chars):" << endl;
        char sentence[81];
        cin.getline(sentence, 81);
        char delims[] = " ";
        char *result = strtok(sentence, delims);
        while (result != NULL)
        {
            for (int i=0; i<=35; i++)
            {
                if (strcmp(result, morse[i]) == 0)
                {
                    if (i >=26)
                        cout << (char)(i+22);
                    else
                        cout << (char)(i+65);
                }
            }
            cout << " ";
            result = strtok(NULL, delims);
        }
    }
    cin >> choice;
    return 0;
}

I think that the newline character is being entered into:
cin.get(sentence, 81);

a solution might be to use:

Code:

while ((choice != 1) && (choice != 2))
{
    cout << "Enter a choice:" << endl;
    cout << "1. Text-to-Morse" << endl;
    cout << "2. Morse-to-Text" << endl;
    cin >> choice;
    cin.get();
}

Hey, thanks a bunch, that fixed it. Well, I used cin.ignore() instead, but thanks for pointing that problem out to me. I was amazed that after fixing that problem, the program works (seeing as I wasn't able to test it before). I was just gonna post another problem about displaying the characters in Morse to Text, but I just solved it, there needs to be parenthesis around the i+48 and i+65. Will edit that in now.

Thanks again
