Nested conditional statements • A conditional statement (i. e. , an if-statement or an if-elsestatement) is also a statement • We can use an if-statement or an if-else-statement in thenpart (and in the else-part) of a conditional statement !!! • Nested conditional statement = a conditional statement where then-part and/or the else-part contains another conditional statement

The switch statement: an Nway selection statement (1) • an intrinsically N-way selection statement:

The switch statement: an Nway selection statement (1) • an intrinsically N-way selection statement: the switch statement

The switch statement: an Nway selection statement (2) • INT-EXPRESSION must be an integer

The switch statement: an Nway selection statement (2) • INT-EXPRESSION must be an integer valued expression • The result of the INT-EXPRESSION is compared to the integer values given in the case clauses • The statements following the case clause up to the break statement are executed • If the result of the INT-EXPRESSION is not equal to any INT -VALUE in the case clauses, then the statements in the default case are executed
