Oct 4, 2016 · Note: we are not supposed to use an 'if' to check for the sentinel, only a while loop; do not use exit or break. Also, we are to be sure to use a sentinel value and two read statements. Code for this program should be similar to the following algorithm: read data // first data while not last data { process data read data }

The use of sentinel for loop: In a sentinel controlled loop the change part depends on data from the user. It is awkward to do this inside a for statement. So the change part is omitted from the for statement and put in a convenient location.

I am trying to understand what sentinel is or how it works with the program. Anyways this is the block of code I am trying to understand. I know it is a sentinel control loop, but I don't know what it does. private static final int SENTINEL = -999 From what I have Googled is that by having a negative integer it indicates the end of a sequence.

If they enter a number you will exit the while loop at reply = scan.nextLine(). You would be better checking !reply.eqaulsIsnoreCase("no)). You then need to handle when reply is a number, cast it to a float, add it to the total and update the count. –

Aug 30, 2014 · while(gender != 0);//begin sentinel controlled while loop Look closely. There is a semi-colon at the end - that is the entire statement. The {} block that follows does not belong to the loop (and is executed exactly once). Try dropping the ; from the end - we've fixed our while loop, but now the {} loop body doesn't execute at all.

May 5, 2015 · It needs to loop continuously until I enter a sentinel value. Once the sentinel value is entered, it will average out the gross pay for me. I've finally got it to where it will continuously loop, asking for pay rate and hours. It calculates income correctly and will loop. Here is my problem. I can't seem to get the sentinel value of -1 to work.

Aug 9, 2015 · Your while loop has no way of changing the value of num1. You need to include asking for input somewhere in the loop. Then just put in 999 or whatever value you want as a sentinel. (I'd suggest reading a line of input and comparing it to the empty string as a sentinel, otherwise parsing it as an int value.) –

Apr 19, 2017 · Write a Java program that will compute the factorial of some numbers n (input from the user, accept only range 1 - 10). For each valid number in input, the output should be the value of n!. Your program should use a loop, to allow the user to input more than one number (count-controlled or sentinel-controlled, your choice)

Feb 1, 2010 · A "sentinel" in this context is a special value used to indicate the end of a sequence. The most common sentinel is \0 at the end of strings. A "sentinel while loop" would typically have the form: while (Get(input) != Sentinel) { Process(input); }

Write a sentinel controlled while loop that will allow you to calculate the average low temperature for any month. The average temperature should be displayed as a properly calculated double value. Explain why you chose the sentinel value. The code for the input of the initial temperature value is provided. Here is my code:
