GCSE Computing/Programming

Starter
The following examples fit the structure of GCSE Computing The code has been written in VB(.net) and C#(.net) In c# // and in VB ' are comments and are ignored by the compiler. They are there to help you.

Programming Language Rules
Every programming language has its rules. Its the main difference between them. A lot of them have some of the same rules.

C#
{} must be used to enclose code
 * must be used at the end of each line of code (to continue the line to the next line don't use the ;)

VB
To continue the line to the next line use _ The code encloses vary

C#
//(type e.g. int or string) (name e.g. i); int i; //integer called i (instead of VBs optional as ... C# uses type object for any type)

VB
dim i as integer //integer called i (as integer optional)

C#
if (Condition e.g. 1=1) { //Do something if true }else{ //Do something if false }

VB
if Condition e.g. 1=1 then 'Do something if true else 'Do something if false end if

C#
int i; //Declare i For (i=0; i<10, i++) { //i is an integer variable and the for checks if i = 10 every loop. If not does the process within then adds 1 to i. }

VB
For i As Integer = 1 To 10 'i is an integer variable and the for checks if i = 10 every loop. If not does the process within then adds 1 to i. Next i

C#
int i; While(i<10) //Checks if i less than 10 { //Loops till i = 10 i++; //Adds 1 to i }

VB
dim i While i<10 'Checks if i less than 10 'Loops till i = 10 i+=1 'Adds 1 to i End While

C#
While(true) { //Does this for as long as the program is open }

VB
Do 'Does this for as long as the program is open Loop
