If Statements

Curly Braces - Syntax Rules

• Curly braces are optional for a then part that is a single statement
• Curly braces are required for a then part that contains more than one statement


• Curly braces are optional for an else part that is a single statement
• Curly braces are required for an else part that contains more than one statement

Truth in Advertising

• Actually, {statement1; statement2; ...} is itself a kind of statement
• So we can say that curly braces are never required

Curly Braces - In Practice

• Always use curly braces
• This will help avoid the error of incorrectly adding a statement
• Exception: the else if construction:

    if (a == b)
    {
        some statements
    }
    else if (a == c)
    {
        more statements
    }
    else 
    {
        even more statements
    }
