The correct answer is: C. three
The three relational operators in the C language are:
<(less than)>(greater than)==(equal to)
These operators can be used to compare two values and return a Boolean value (true or false). For example, the following statement will return true if the value of x is less than the value of y:
x < y
The following statement will return true if the value of x is greater than the value of y:
x > y
The following statement will return true if the value of x is equal to the value of y:
x == y
The relational operators can also be used in logical expressions. For example, the following statement will return true if the value of x is less than the value of y or the value of x is equal to the value of y:
x < y || x == y
