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.
|An if statement consists of a boolean expression followed by one or more statements.|
|An if statement can be followed by an optional else statement, which executes when the boolean expression is false.|
|A switch statement allows a variable to be tested for equality against a list of values.|
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).|
