A program sorts string data using different sorting methods. One source file is used to answer Question 1. The file is called Data.txt

1. (a)The text file Data.txt stores string data items. Each data item is on a new line in the text file. The function ReadData(): • has a local array of strings that can store 45 items • reads each line of data and stores it in the array • returns the array. Write program code for the function ReadData(). Save your program as Question1_N24. Copy and paste the program code into part 1(a) in the evidence document.[6]
2. (b)(i)The function FormatArray() takes an array of strings as a parameter. It concatenates the contents of the array into one string with a space between each array element. The function returns the concatenated string. Write program code for FormatArray(). Save your program. Copy and paste the program code into part 1(b)(i) in the evidence document.[2]
3. (b)(ii)The main program: • calls ReadData() and stores the returned array • calls FormatArray() with the returned array and outputs the returned string. Write program code for the main program. Save your program. Copy and paste the program code into part 1(b)(ii) in the evidence document.[3]
4. (b)(iii)Test your program. Take a screenshot of the output. Save your program. Copy and paste the screenshot into part 1(b)(iii) in the evidence document.[1]
5. (c)The function CompareStrings(): : takes two strings as parameters • compares each string, one character at a time, to identify which string comes first alphabetically. If the first two characters are the same, the second character of each string is compared. This continues until the two characters are different. The function: • returns 1 if the first parameter comes before the second alphabetically • returns 2 if the second parameter comes before the first alphabetically. Write program code for CompareStrings(). Assume that all strings are in lower case. Assume that a difference between two strings will always be identified before the end of one string is reached. Do not use an in-built string comparison function. The strings must be compared one character at a time. Save your program. Copy and paste the program code into part 1(c) in the evidence document.[4]
6. (d)(i)The function Bubble() takes an array of strings as a parameter and sorts the data into ascending alphabetical order, using a bubble sort. The bubble sort uses CompareStrings() to compare each string. The function returns the sorted list. Write program code for Bubble(). Save your program. Copy and paste the program code into part 1(d)(i) in the evidence document.[3]
7. (d)(ii)Write program code to amend the main program to: • call Bubble() with the unsorted array as a parameter • call FormatArray() with the sorted array and output the returned string. Save your program. Copy and paste the program code into part 1(d)(ii) in the evidence document.[2]
8. (d)(iii)Test your program. Take a screenshot of the output. Save your program. Copy and paste the screenshot into part 1(d)(iii) in the evidence document.[1]
