make sure that I want to answer clear with flowchart and program and handwriting trace

Objective: by the end of the experiment the student should be able to use For loops with 2D array. Task: Write a C++ program the declare 2 D array for fractional numbers 3 rows and 6 columns, assign values to the array using the same line of declaration using nested curly braces, (show the code then comment) how to assign values to the array using the same line of declaration using single curly braces, (show the code then comment) how you ask the user to enter each element of the array content, compute the sum of each row and store the result in the last column, starting from cell 0,0 compute the average of the diagonal elements, handwriting trace of the code for all iterations and epochs are required. Solution Flowchart: Program: Handwriting trace
