The if Statement

The if statement is used to test a condition and execute a statement or statements based on the condition. The if statement has the following syntax:

if (condition)

   statement    // condition is true

 

In the above example, if condition is true, then statement is executed. You can use {} brackets to group more than one statement. For example:

if (condition)

   {

   statement1

   statement2

   }

 

An else clause can be added to the if statement:

if (condition)

   statement1    // condition is true

else

   statement2    // condition is false

Source Insight evaluates the whole condition expression, unlike C/C++ which performs partial evaluation. See: Conditional Evaluation.
