Which one is the correct syntax for C++?.

• if [ gross > 100000 ] then

  net = gross - tax;

• if ( gross > 100000 )

  net = gross - tax;

• if { gross > 100000 } then

  net = gross - tax;

• if < gross > 100000 > then

  net = gross - tax;

If I want to execute multiple statements as part of an if condition, I enclose those statements between:

• ( )

• [ ]

• { }

• < >

In C++, Is it possible to have an if statement inside an if statement?.

• Yes.

• No.

• It depends.

In C++ the switch statement is more useful when:

• You are using a single variable or simply expression

• When you have multiple variables or selection expressions

• When you have multiple selection expressions but one variable

• When you have multiple variables but one simply expression.
