The for loop has to be the most flexible and simplest mechanism for performing iterations in C# and many other languages. In C# there are several forms to this loop
Basic structure
for( statement-1; statement-2; statement-3 )
Each statement is optional and serves a very specific purpose
Statement | Intent |
|---|---|
statement-1 This is the initialiser. It should set up the parameters for the loop condition. It could be written outside of and before the for loop |
It is usual that the first statement simply sets up some initial values for the loop. Any variables declared at this point only exist withn the scope of the for loop. |
statement-2 The is the condition statement. It should perform a test to determine if the loop should continue. It could be writen in the code block of the for loop. If no longer true a forced exit from the loop can be triggered. |
Whilst the condition is true, the code block below the for statement will be executed |
statement-3 This is the iterator statement. It should increment/decrement the variables that are used in the conidition statement. It could be written in at the end of the code block. | x++; At the end of the execution of the code block, statement-3 (in this case |
