C# 0 The Complete Reference

a

b

, and 

c

, by use of a comma-separated list. As mentioned earlier, 

when you need two or more variables of the same type, they can be declared in one statement. 

Just separate the variable names with commas.

The for Loop

You can repeatedly execute a sequence of code by creating a 

loop.

 C# supplies a powerful 

assortment of loop constructs. The one we will look at here is the 

for

 loop. Like the 

if

statement, the C# 

for

 loop is similar to its counterpart in C, C++, and Java. The simplest 

form of the 

for

 loop is shown here:

for(

initialization

;

 condition

;

 iteration

)

 statement

;

In its most common form, the 

initialization

 portion of the loop sets a loop control variable 

to an initial value. The 

condition

 is a Boolean expression that tests the loop control variable. If 

the outcome of that test is true, the 

for

 loop continues to iterate. If it is false, the loop terminates. 

The

iteration

expression determines how the loop control variable is changed each time the 

loop iterates. Here is a short program that illustrates the 

for

 loop:

// Demonstrate the for loop.

using System;

class ForDemo {

  static void Main() {

    int count;
