PROGRAMMING TASKS BOOKLET

NAME: ___________________________________________

Throughout the booklet you will create a program to answer each task.

Write answers down next to the word answer and proe using a procedure you haewritten.

!ou will be asked to check the syntax o" the language.

!ou will declare ariables appropriately.

!ou are allowed to use the #nternet to research some o" the terminology.

Task 1 Writing your first program

$pen %isual &tudio and "amiliarise yoursel" with the enironment.

'reate a new console application and sae it in your exercises "older with anappropriate name.

Write a program which displays the text ()ello World* on screen. #t shouldpause so that the message can be iewable by the user.

Add additional lines o" code so that a story is displayed on the screen+ i.e. alittle ditty:
