Assignment #1 - Skyscrapers Background: The purpose of this assignment is to review lectures in 2D-array, nested for loops, file input (scanner). This assignment will give you practice working with single and multi- dimensional arrays as well as basic data structures. The students will also be able to develop and implement program involving the fundamental programming constructs such as variables, types, expressions, assignment, simple I/O, conditional and iterative control structures, functions and parameter passing, structured decomposition. Objectives: This assignment will assess your mastery of the following objectives: o Write a functionally correct program to produce specified console output. Use nested for-loop to check the content in the 2D array. Operate the file I/O (input/output) to read data from and write to file using Scanner class. o Follow prescribed conventions for spacing, indentation, naming methods, and header comments. d
