Reading Input Real-Time

I'm trying to code a program to read the user's input and have it:

-count vowels
-stop counting vowels after '.' or '?' (ie. abcdjwef is 1 a, 1 e; while fje.fwdfeiii is just 1 e)
-closes when ENTER is pressed after a '.' or '?' is found (ie. closes after 'abacds. ENTER' as well as 'as.fefsdf ENTER')
-display the number of vowels

Is there any way to do this with only 'cin >> userInput' and a while loop checking for punctuation?

Code:

---

char userInput = NULL; //userInput initialized

/*******************************************************
while userInput not equal to '.', '?', or carriage return and newline or just
carriage return, depending on your system
********************************************************/
while (!(userinput == '.' || userinput == '?' ||userinput == '\r\n'))
{
    cin >> userInput
   
    /* The vowel calculation code
    *  goes here
    */
}

/*
* The if/elseif/else condition to test userInput for one of the delimiting
* characters goes here
*/
if(userinput == '.' || userinput == '?' )
    //stop counting vowels, that's all
else
//userInput is equal to carriage return, this part may get dicy, apply your intelligence
    //do cleanup work and output of the program
    exit(0);

exit(1);

The exit(0) indicates a succesful completion of the program and exit(1) indicates failure. Feel free to use them at free will, but carefully.
