The Problem: Buffering of output can lead to unexpected results For example: std::cout << “Doing unrelated stuff” << std::endl; do_stuff(); std::cout << “Doing divide ... “; i = 1/0; // Divide by zero std::cout << “complete\n”; When runs this program prints (on some systems): Doing unrelated stuff Floating point exception8 From this output we can see that the problem is “obviously” in the do_stuff function. What's going on? The problem is that output is being buffered. So the string “Doing divide ...” goes into the buffer, then the program crashes with a divide by zero error, and the output is never displayed. This is where the confusion comes from

Problem Y: Implement the reader writer problem using pthreads and semaphores. You should allow multiple readers to read at the same time and only one single writer to write to the data set. You are required to use the following: 1. A semaphore rw_muter initialized to 1. 2. A semaphore muter initialized to 1. 3. An integer reader_count initialized to 0.

JAVA CODE PLEASE Functions With No Parameters and Return Values Quiz by CodeChum Admin Create a function named banner that prints “CodyChum” with a newline. In the main function, write a program that accepts an integer input which would serve as an inclusive stopping point of a loop iteration that starts at the value of 1. If the number that loops through the range is divisible by either 2 or 3, then call the banner function, otherwise just print the number. Input 1. One line containing an integer Output First line is the integer user input. Succeeding multiple lines containing an integer or “CodyChum” 10 1 CodyChum CodyChum CodyChum 5 CodyChum 7 CodyChum CodyChum CodyChum
IN MAGICFS LANGUAGE The Fibonacci sequence begins like this: 0,1,1,2,3,5,8,13,21,... A number in the sequence is the sum of the previous two numbers in the sequence, with first two being 0 and 1. Implement a function named 'fibonacci' that expects a working value of an integer index, and returns the Fibonacci number at that position in the sequence. The index is zero-based. For instance, if given a value of 4, the function should return 3 because the sequence is 0, 1, 1, 2, 3, ... Use subroutines if necessary. Your answer will be evaluated for partial credit. Comments are encouraged.
