This is the simplest decision control structure. It includes a statement or block of statements on the “true” path only. If the Boolean expression evaluates to The general form of the statement is PHPif (Boolean_Expression) { /* A statement or block of statements */ ; }
When only one single statement is used in the if (Boolean_Expression) /* One Single Statement */ ; or you can even write the statement on one single line, like this: if (Boolean_Expression) /* One Single Statement */; The braces are required only when
more than one statement is used in the

What statement do you use to write a single alternative decision structure?This is the simplest decision control structure. It includes a statement or block of statements on the “true” path only. If the Boolean expression evaluates to true , the statement, or block of statements, of the structure is executed; otherwise, the statements are skipped.
What statement is a multiple alternative decision structure?The conditions in a multiple alternative IF statement are evaluated from top to bottom until a true value is obtained. The statement sequence following the first true condition is executed and the rest of the IF statement is skipped. If every condition is false, statement sequencen (between ELSE and END ) is executed.
What is a structure that allows the computer to make a decision between alternative conditions?A decision structure (AKA selection structure) allows a program to perform actions only under certain conditions. Takes a Boolean expressions as its operand and reverses its logical value.
Which structure can execute a set of statements only under certain circumstances?Decision structure executes a set of statements under certain conditions.
