VB.NET Procedural Programming Exercises

To complete this exercise the learner will need to implement basic selection (IF and else IF) to determine the calculation to be performed by the calculator: either add, divide, subtract or multiply. The exercise also requires the learner to use techniques such as the concatenation of string and basic operations, as well as the implementation of variables to store the users’ input. General system methods are also required to read and write content to/from the console.

To complete this exercise the learner will need to implement a single IF statement (or CASE statement) to compare the users’ input against a pre-defined username and password. This exercise requires the implementation of the keyword ELSE (or CASE ELSE if using CASE) to catch any other possibilities (in this case, incorrect user details). This exercise will also require the learner to concatenate outputs, implement variables to store user input and utilise system methods to read and write content to/from the console.

To complete this exercise the learner will need to implement several selection statements, either IF or CASE, to determine the order of a customer. The learner will then need to use basic maths to calculate the total of the order and display it on the screen. This exercise will also require the learner to concatenate outputs, implement variables to store user input and utilise system methods to read and write content to/from the console.

To complete this exercise the learner will need to implement two FOR loops to repeat a sequence. The learner is required to use the step command to change the increment value of the loop. Both loops will also have a start and end point which will be specified by the user. To complete this exercise the learner will need to use previous techniques already learnt, including concatenation, system variables and system methods (both read and write).

To complete this exercise the learner will need to implement two loops to repeat a sequence – a loop inside a loop. The learner is also required to use selection techniques (either CASE or IF) that were practised previously in the earlier exercises. To complete this exercise the learner will need to use previous techniques already learnt, including concatenation, system variables and system methods (both read and write). This exercise also introduces how to generate a random number using the ‘Random’ class.

To complete this exercise the learner will need to nest a loop inside another loop. The outer loop will create a blank ‘WriteLine’ and the inside loop must use the ‘Write’ method to add the required number of asterisks to the same line. The outer loop will require a start and end point to be specified by the user. To complete this exercise the learner will need to use previous techniques already learnt, including system variables and system methods (both read and write).

This exercise will require the learner to make code more efficient and manageable by grouping code together in separate methods and functions. The exercise will reinforce other techniques previously learned, such as selection, iteration, concatenation, numerical operators, the implementation of variables to store user input and system methods to read and write content to/from the console. This particular exercise will also require the learner to work with basic percentages.

To complete this exercise the learner is required to combine techniques used in previous exercises and apply them to this new scenario. This particular exercise will require knowledge of percentages and rounding numbers to two decimal places. The exercise will also reinforce other techniques previously learned, such as selection, iteration, concatenation, numerical operators, the implementation of variables to store user input and system methods to read and write content to/from the console.

To complete this exercise the learner is required to look at a new technique: arrays. Arrays enable multiple values to be stored in a single variable, thus reducing the code. The exercise will also reinforce other techniques previously learned, such as selection, iteration, concatenation, numerical operators, the implementation of variables to store user input and system methods to read and write content to/from the console.

To complete this exercise the learner is required to write an algorithm that works out the number of stations between a start and end point, so that a price can be determined; there are numerous ways in which this can be achieved. Printing a receipt to file would make an excellent extension to this task; read the supporting theory for help on how to achieve this. The exercise will reinforce other techniques previously learned, such as selection, iteration, concatenation, numerical operators, the implementation of variables to store user input and system methods to read and write content to/from the console.

To complete this exercise the learner is required to write a boxing buzzer that will act as a timer and count the number of boxing rounds. To complete this exercise, the learner will need to use iteration and a new technique called threading. The exercise will reinforce other techniques previously learned, such as selection, the implementation of variables to store user input and system methods to read and write content to/from the console.
