Decision making structures require that the programmer specify one or more conditions to be evaluated or tested by the program, along with a statement or statements to be executed if the condition is determined to be true, and optionally, other statements to be executed if the condition is determined to be false.
C++ programming language provides following types of decision making statements.
| Statement | Description |

if...else statement | An if statement can be followed by an optional else statement, which executes when the boolean expression is false. |

nested if statements | You can use one if or else if statement inside another if or else if statement(s). |
nested switch statements | You can use one swicth statement inside another switch statement(s). |
