2D arrays in pseudocode

Question

Hello everyone I'm working on an assignment where I have to read records from a file and load them in parallel arrays. the student names are in a 1D array and the three marks for that student are in a 2D array. I need to load these and Im not sure how to use 2D arrays in pseudocode plz help thanks

FWIW here's my attempt at some pseudo-code: READ all lines from students.txt into a 'lines' array STORE the number of elements in 'lines' in 'len' CREATE an array 'names' of length 'len' CREATE a two dimensional array 'marks' whose dimensions have lengths 'len' and 3 FOR i = 0 TO len - 1 TRIM lines[i] of any leading or trailing space SPLIT lines[i] into 4 individual items using a comma as separator STORE the items in an 'items' array names[i] = items[0] FOR j = 1 TO 4 CONVERT items[j] to an integer 'k' marks[i j-1] = k NEXT j NEXT i I've expressed the 2 dimensional array using the marks[ij] syntax rather than marks[i][j]. This is because the array is rectangular rather than jagged and C# distinguishes between the two using the above syntax.

The format of pseudocode is determined by you. It is anything that helps you. If it has a format defined by someone else then it is not pseudocode. If someone such as a professor says that pseudocode is supposed to be in a specified format then you must get that format from that professor.

I'm not too good at pseudo-code but if it helps here's the C# code to do what you want: using System; using System.IO; class Program { static void Main() { string[] lines = File.ReadAllLines(students.txt); // read all the lines into an array int len = lines.Length; // find the number of lines string[] names = new string[len]; // create a 1D array of students int[] marks = new int[len 3]; // create a 2D array of marks in the same order as the students for(int i = 0; i { string[] items = lines[i].Trim().Split(''); // assume data is comma separated in file names[i] = items[0]; // name is the first item for(int j = 1; j } // check it worked for(int i = 0; i { Console.WriteLine({0-20} {13} {23} {33} names[i] marks[i 0] marks[i 1] marks[i 2]); } Console.ReadKey(); } }
