@Txsl the best way to learn something psychologically, is to apply the knowledge and tie it to whatever you already know.
Next assignment is using text I/O or scanners make a program that takes the users first name, last name, age and initial balance print out a string saying "Hello (first name) + (last name) your current balance is (double + increment by one using incrementation "shortcut").
For assignment 3 do the exercise question in chapter 2, 2.1-2.4, not 2.5 unless you want to but I won't be covering that section yet.
Then do the practice quiz. All the solutions are posted on the site.
Assignment 4 part 1 will consist of upgrading assignment 2 to output "please enter correct input" and not stop execution unless so sort of input is received. This will require both a while loop and and if/else statement with a control Boolean value that will be able to end the while loop if the user inputs correct values.
