Answer / ksk
Entry Comtrolled will check the Condition at First and
doesn't execute if it is False.
Exit Comtrolled will check the Condition at Last and at
least once the statement will execute though it is False .

Answer / s.s.venkatesh
Entry control is otherwise called as WHILE loop,because the
while loop checks the condition at first,and then only
execute the following instructions.
Exit control is also called as DO WHILE loop,because the do
while loop checks the condition at last

In Entry controlled loop the test condition is checked
first and if that condition is true than the block of
statement in the loop body will be executed while in exit
controlled loop the body of loop will be executed first and
at the end the test condition is checked,if condition is
satisfied than body of loop will be executed again.
How's Thisssssssszzzzzzzz.........

Answer / ajay pandey
The entry control loop is also called for or while loop. Because while loop and for loop are check condition first and the condition is true then it execute the inside statement otherwise it is exit. Where do-while loop is atlist one time execute the inside statement and then check condition. Therefor do-while loop is exit control loop.

Answer / prathika
entry check loop:
first the condition of the loop wll be checked if the condition is true then the body of the lop will be executed
if the condition is not satisified the loop will not be executed
ex:for,while
exit check loop:
the conditio is placed at the end the statment will be executed atleast once even if the condition fails
ex:do while

In Entry controlled loop the test condition is checked first
and if condition is true than the bock of statement in the loop body will be executed while in exit controlled loop the body of loop will be executed first and at the end the test condition is checked, if condition is satisfied then body of loop will be executed again..

Answer / varsha
Entry checking loop works on while statement, Exit checking loop works on do....while statement.
Entry checking loop will check the condition at the very beginning and if the condition is false,it won't work......
The exit checking loop will check for the condition at the last and even if the condition is false,it will work at least once
Ex for entry controlled loop:
int i=6;
while(i<5)
{
System.out.println("hello");
}
Output:
no output...
Ex. for exit controlled loop:
int i=6;
do
{
System.out.println("hello");
}
while(i<5);
Output:
HELLO.....

Answer / rahul singh
entry controlled loop first test the terminating condition and then execute the loop body.If the condition is found true he loop body is execute other wise the loop terminates.It is also called pre-tested loop.or Top -Tested loop.
An exit control loop first execute the loop bod and then test the terminating condition.If the condition is found true the loop body execute again otherwise the loop terminates.It is also called Post Tested loop or Bottom Tested loop.

Topics: Structures, Arrays, Searching and Sorting Assume there is a small mobile computer device including a hard disk and a slot for a memory card. The device shall be used to backup photos e.g. during holiday. Every time a memory card is connected all photos of the card are copied into a new folder automatically. And your task is to develop some basic controlling software to show, add, remove, search and sort the directories of photos. Step by Step Implementation 1.Define two symbolic constants, one to hold the total volume of the disk (e.g. VOLUME) and another one to hold the number of entries the files system of the device can handle (MAXFOLD). 2.Define a new structure data type named DATE to store a date consisting of year, month and day as unsigned values. 3.Define an other structure data type FOLDER to store the information of one folder of photos: ◦A title as character array of appropriate length ◦The location (event) the photos are taken as character array of appropriate length ◦The date of the day the photos are copied to the disk using the just defined data type DATE ◦The number of photos as natural number ◦And the size of the folder in MB as floating point value 4.Define the following global variables and initialise them: ◦disk as an array with MAXFOLD elements of data type FOLDER ◦folders as natural value to count the number of folders currently stored at the disk (valid elements in the array) TEST: Now you should be able to compile the code the first time without any warning or error. In the menu only "p" to print and "q" to quit will work!. 5.Now complete the functions given by their prototype: float freeSpace ();The function has to calculate the sum of the size component of all elements currently stored in the disk array. The function shall return the free space of the disk by the difference between the available total volume and the calculated sum. TEST: To test this function you only need to uncomment printing the "statusline" at the function actionmenu(). Compare the calculated value with a manual calculation of the example values given above. unsigned isBefore (DATE, DATE);The function checks if one date is before the other. There are 3 different possibilities which have to be handled. Imagine for example these 3 different combinations of values: ◦2010-01-01 : 2010-01-02 ◦2010-01-01 : 2010-02-01 ◦2010-01-01 : 2009-01-01 The function shall just return the result of the comparison. unsigned isEqual (DATE, DATE);The function checks if one date is equal to the other, all components have to be compared. The function shall just return the result of the comparison. int findByDate (DATE);As the array is should be kept in order (sorted by date) implement a binary search for a folder by its date here. You need only to adapt the binary search we used in the exercise. Use the 2 comparing functions above where appropriate. The function shall return the index of the element which was found or -1. TEST: Now you can try searching a folder by date via the "s" in the menu. Activate the corresponding part in the main function. int isSpaceLeft (FOLDER);This function compares the free space of the disk with the size of folder given with the parameter list. The function shall return 1 if there is enough space to add the folder, otherwise 0 (just the result of the comparison). void SortByDate ();This function shall implement the InsertionSort using the component date as key. Use the provided algorithm/souce code of the exercise as template. If you need a comparison between dates, use the function isBefore you have written again. void addFolder (FOLDER);The function has to check if the disk has additional capacities to add the new folder (number of folders and space left). If at least one of these conditions is false print an error message and return -1. Else there has to be added an other test to avoid 2 folder elements with the same date (use the findByDate function here. If there is no folder with the new date simply attach the new folder at the end of the array and call the sorting algorithm afterwards to keep the order in the array. TEST: Now you can try to add a folder via the "a" in the menu. Activate the corresponding part in the main function. void delDir (int);This function removes one element of the disk array. The input parameter contains the index of the element to delete. Deletion can simply be done by moving all elements at the right one to the left (overwriting the element to delete. The function may get a -1. This has to be checked first (certainly there is nothing to delete then!) Don't forget to decrement the counter of elements at the end. TEST: Now you can try to remove a folder by date via the "r" in the menu. Activate the corresponding part in the main function. unsigned findAllOfLocation(char[], FOLDER[]);This is an optional additional task: The function shall find all elements with the given value for the component location (first input parameter). The array elements which are found have to be added to the FOLDER array (second input parameter). As this parameter is an array we can use the result later in the main function. There kernel of function implements a modified linear search on the disk array (it does not stop if one element is found bat continues search until the location of all elements is checked). The finally function shall return the number of elements found in the disk array. TEST: Now you can try to add a folder by date via the "l" in the menu. Activate the corresponding part in the main function.
