An incomplete algorithm has been written in pseudocode to count the number of zeros stored in an array and total the non-zero values. 01 DECLARE A[1:50] : INTEGER 02 DECLARE C : INTEGER 03 DECLARE I : INTEGER 04 DECLARE T : INTEGER 05 I ← 0 07 FOR C ← 1 TO 50 08 IF A 09 THEN 10 T ← T + 1 11 ELSE 12 I ← I + A 13 ENDIF Complete the given pseudocode algorithm. Write the pseudocode to display, with suitable messages, the number of zeros stored in the array and the total of the non-zero values. Meaningful identifiers have not been used in the algorithm. Suggest suitable meaningful identifiers for: The array: A The variables: T C I

An incomplete algorithm has been written in pseudocode to count the number of values stored in an array and to find their average. Values have been stored in the array starting at A All the values to be counted are non-zero. A value of zero in the array indicates there are no more values stored. 01 DECLARE A : ARRAY[1:50] OF INTEGER 02 DECLARE C : INTEGER 03 DECLARE W : INTEGER 04 DECLARE X : INTEGER 05 W 06 C 07 WHILE A <> 0 08 W 09 C C + 1 10 ENDWHILE 11 X Complete the given pseudocode algorithm. Write pseudocode to display, with suitable messages: • the number of values stored in the array • the average of those values stored. Meaningful identifiers have not been used in this algorithm. Suggest suitable meaningful identifiers for: The array A The variables C X W

A two-dimensional (2D) array Contacts is used to store names and telephone numbers. All the data is stored as strings. The array must have the capacity to store 100 contacts in the form of: • column 1 – contact names as: last name, first name for example: Smith, John • column 2 – telephone numbers. The variable CurrentSize shows how many contacts are in the array. Write a program that meets the following requirements: • display a menu of choices: ○ enter new contact details ○ display all the contact details ○ delete all the contact details • validate the menu input • allow up to a maximum of five new contacts to be added to the array at any one time • do not allow more than 100 contacts in total • after new contacts have been added, sort the array by contact name, as long as there are at least two contacts in the array • output the whole of the array • delete the contents of the array. You must use pseudocode or program code and add comments to explain how your code works. You do not need to declare any arrays, variables or constants; you may assume that this has already been done. All inputs and outputs must contain suitable messages. You do not need to initialise the data in the array Contacts and the variable CurrentSize
