Definition: The if statement specifies a condition and one or two blocks of code. When the condition evaluates to anything other than false or zero the first block of code is run. If a second block of code is specified in an else clause then that block of code will run when the first block doesn't (ie when the condition evaluates to false or zero). If is a reserved word and cannot be used for anything other than declaring an if statement.
Examples:if (a == b) break;
