The syntax of the ternary operator is:

condition ? expressionIfTrue : expressionIfFalse;
We can represent nested conditional statements as ternary operators (already discussed in the previous chapter). The
above example can be written using Ternary Operator as:
max = (a>b)? ((a>c)? a: c) : ((b>c)? b : c);

Switch Case
Switch Case is a multiple-branch selection statement in which multiple conditions can be checked at once. It uses a
variable that selects one of many codes (cases) to be executed.
The value of the variable or the expression is checked with the value of each case. When a match is found, the associated
block of code is executed. If no case is matched, the code of the default case will be executed which is provided at the
end of the switch statement.
Note: The data type of the expression or the variable provided in the switch statement must match with
the data type of the case value or expression.

Syntax:

switch(choice)
{
case value1: sequence of statement1;
break;
case value2: sequence of statement2;
break;
case …..

default: statements;
