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.
Following is the general from of a typical decision making structure found in most of the
C++ programming language provides following types of decision making statements. Click the
following links to check their detail.
We have covered conditional operator ? : in previous chapter which can be used to replace
if...else statements. It has the following general form:
Exp1 ? Exp2 : Exp3;
Where Exp1, Exp2, and Exp3 are expressions. Notice the use and placement of the colon.
The value of a ? expression is determined like this: Exp1 is evaluated. If it is true, then Exp2
is evaluated and becomes the value of the entire ? expression. If Exp1 is false, then Exp3 is
evaluated and its value becomes the value of the expression.
