You are expected to write a statistical interpreter that perform some statistical function by issuing commands at the command prompt. When run, your interpreter should show a prompt $ and should allow users to key in a command and its parameters. The interpreter must verify whether the command is syntactically correct or not and must display an error message when a wrong command. Each command is executed immediately after pressing the enter key. The interpreter should allow users to handle four types of commands: file operations, statistical operations, display operations, and add/delete operations. 1. File Operations Your interpreter should allow users to issue commands to load, store, and clone files. The interpreter can read and write files of the format shown below: 5 100 Id, Age, Math, Science, Malay String, number, number, number, number 11920100, 19, 93, 92, 87 11920111, 20, 76, 87, 75 : : 1221302345, 19, 20, 02, 20 Command Load Store Clone html html example $ load salary.csv $ store salary.csv $ clone salary.csv s2.csv $ html salary.html Shtml a.csv a.html data.csv 5 → the number of columns in the file. 100 ➜ the number of data rows in the file. Column names separated by comma. The type of each column (only string and float) data row 1 separated by comma. data row 2 separated by comma. data row 100 separated by comma. Function Reads the file named filename and parses its contents and stores it into arrays or vectors. The interpreter handles one file only. Save the active array or vectors into a csv formatted file with the name filename Create a copy of file1 and name it file2. You are not expected to handle multiple folders and switch folders. Generates an HTML document for the loaded data and store it in a file "salary.html". You must decide on the format. The file to be viewed by a web browser. The program should read the a.csv file and convert it to an html table with proper column titles and format.
