Project description
There are three simple tasks to be done in Delphi (i.e., a separate project).
Task 1: Enter n numbers. We write evenly in a text file in a line. We put odd ones on the screen in a column.
Task 2: There is a 2-level array of numbers 1234 (top line) and
5678 (bottom line). After the program is launched, the top and bottom lines should be changed: 5678 (top line), 1234 (bottom line). In the attachment there is already a program it must be remade under these numbers and the specified condition.
Task 3: Same as the second task, only you need to get the inscription "enter the first 4 numbers of the array" at launch. And then the second line "enter the last 4 numbers of the array". The result of the program is the same as in the second task.
Requirements:
1.Text please provide comments because you need to explain later to the teacher) Comments only in key places at least)
2. You need to use the nested program as a standard. Just remodel under the condition of each task.
