Chapter 4.1, Problem 4.3CP
A)
Program Plan Intro
Relational Operators:
Relational operators are used to compare numeric and character values using the following operators:
- Greater than (>)
- Less than (<)
- Greater than or equal to (>=)
- Less than or equal to (<=)
- Equal to (==)
- Not equal to (!=)
These operators will determine whether specific relationship exists between two values of same type.
Relational Expression:
- Relational operators are “binary”, so it needs two operands for comparison. Consider the following expression using the less-than operator:
A < B
- The above expression is called a “relational expression”. It is used to find whether “A” is less than “B”.
- Relational expression is also referred as “Boolean expression”, because the resultant value of all relational expression is either “True” or “False”. But the states of Boolean values are stored as 0 and 1.
- Hence, if the resultant value of relational expression is 0, then the expression is “False”. If the resultant value of relational expression is 1, then the expression is “True”.
