This sorting algorithm is an in-place comparison-based algorithm in which the list is divided into two parts, the sorted part at the left end and the unsorted part at the right end. Initially, the sorted part is empty and the unsorted part is the entire list. The smallest element is selected from the unsorted array and swapped with the leftmost element, and that element becomes a part of the sorted array.
In a menu driven program, the user is given a set of choices of things to do the menu and then is asked to select a menu item. The driver then calls an appropriate function to perform the task selected by the menu item.
A switch statement seems a natural one for handling the selection from the menu. We will modify the simple version of our payroll program to make it menu driven.
While a menu is not needed in this case, we use it to illustrate the concept. The menu items are: The user selects a menu item to execute a particular path; for example, new data is read only when the user selects the menu item, get data.
On demand, the current data can be displayed so the user may make any desired changes. Pay is calculated only when the user is satisfied with the data. The driver of any menu driven program will look similar to this.
The program prints the menu and then reads a selection character. A switch is used to select the path desired by the user. The user may type a lower or an upper case letter; both cases are included by the case labels.
Usually, the driver hides the details of processing individual selections, so we have implemented most selections as function calls. The only exception here is when the selection is get data where the actual statements to read the necessary data are included in the driver itself because to use a function, it would have to read several items and somehow return them.
So far we only know how to write functions that return a single value. We will address this matter in Chapter. Notice what happens if the user elects to quit the program: This function is like a return statement, except that it terminates the entire program rather than return from a function.
It may be passed a value which is returned to the environment in which the program runs. A value of 0 usually implies normal termination of a program; any other value implies abnormal termination. After the appropriate function is called, we terminate the selected case with a break statement to end the switch statement.
The control then passes to the statement after the switch statement, namely flushing the buffer. Let us see what would happen if this flush were not present. The user selects an item by typing a character and must terminate the input with a newline.
The keyboard buffer will retain all characters typed by the user, including the newline. So if the user types: When the break ends the switch, control returns to the while expression which reads the next character in the buffer:Insertion Sort in Java.
We can create a java program to sort array elements using insertion sort. Insertion is good for small elements only because it requires more time for sorting . Using only one program implement bubble sorting insertion sorting quick sorting and selection sorting?
Its simple!dirve a menu based prog by using switch case & then apply every sorting function .
Dec 09, · Sorting strings using selection sort method? I am trying to write a program to sort the characters in a word alphabetically. For example, if you input 'what', the computer will sort it into 'ahtw'.
Tutorial - Write a Shell in C you need to use the function chdir(). The thing is, the current directory is a property of a process. the man pages are your best friend.
If you don’t know what sort of interface the C library and Unix offer you, I would point you toward the POSIX Specification, specifically Section 13, “Headers”.
You. The only exception here is when the selection is get data where the actual statements to read the necessary data are included in the driver itself because to use a function, it would have to read several items and somehow return them. So far we only know how to write functions that return a single value.
