Answer:
Logical Expressions
Explanation:
The expressions that have logical statements which could be "true or false" are known as logical expressions. These types of expressions are also known as Boolean Expressions.
These expression are used in computer programming. The purpose of these expressions in programming is to make a decision that could be based on different conditions. These conditions could be true or false. This is the main reason that. logical expression makes best sense for values received in true or false.
Answer:
c. decDiscount = GetDiscount(decSales, decRate)
Explanation:
Option a. is incorrect because it is using Call word which is not a valid way to invoke a function.
Similarly option b. is also incorrect because it uses Call word to invoke function GetDiscount() which is not a valid way to call a function and also it is passing it the contents of three variables decSales, decRate and decDiscount and as mentioned in the question only two parameters are to be passed to GetDiscount() function.
Option c. is correct as it invokes the function GetDiscount() and passes it the contents of two variables decSales and decRate and assigns this to a variable decDiscount. For example if the GetDiscount() method has to calculate the discount using decSales and decRate then the resultant value of this computation is assigned to decDiscount. So whatever this function returns or computers is assigned to and stored in decDiscount variable. So this is a valid way to invoke a method.
