What is the purpose of relational operators in C++?

To compare numeric and char values to determine relative order

The relational operator >= represents 'Less than or equal to'.

False

Match the following relational operators with their meanings:

< = Less than

= Greater than = = Greater than or equal to <= = Less than or equal to

Which relational operator is used to determine if a value is greater than another value?

>

What is the purpose of the relational operator >= in a C++ program?

To determine if a value is greater than or equal to another value

Which of the following expressions is true if the value of x is 5 and the value of y is 7?

x < y

What is the result of the expression 5 >= 7 in a C++ program?

false

Which relational operator is used to determine if a value is less than or equal to another value?

<=

What is the result of the expression 7 > 5 in a C++ program?

true

Match the following relational operators with their meanings:

< = Less than

= Greater than = = Greater than or equal to <= = Less than or equal to

Match the following relational operators with their examples:

= 7 is true when compared to 5 <= = 5 is true when compared to 7 = = 5 is true when compared to 5 < = 5 is true when compared to 7

Match the following relational operators with their usage:

= Determining if a value is greater than another value < = Determining if a value is less than another value <= = Determining if a value is less than or equal to another value = = Determining if a value is greater than or equal to another value

Match the following relational operators with their opposite:

= <= < = >= = = < <= = >

Match the following relational operators with their usage in C++ programs:

= Evaluates to true if a value is greater than another value < = Evaluates to true if a value is less than another value = = Evaluates to true if a value is greater than or equal to another value <= = Evaluates to true if a value is less than or equal to another value

Match the following relational operators with their purpose:

= Comparing numeric values to determine relative order < = Comparing char values to determine relative order = = Determining the relative order of numeric and char values <= = Validating user input in a C++ program

Study Notes

Chapter 4: Making Decisions

Relational Operators

  • Relational operators are used to compare numeric and char values to determine relative order.
  • The relational operators are:
    • &gt; (Greater than)
    • &lt; (Less than)
    • &gt;= (Greater than or equal to)
  • Example: The expression 5 &gt;= 7 is evaluated as false.
