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.

What is the relationship between interoperability and the other quality attributes highlighted in this book? For example, if two
Lina20 [59]

Answer:

Interoperability is the ability of or degree to which two or more systems usefully exchange information via interfaces in particular context. Interoperability can be defined in two ways which includes the ability to exchange data (syntactic interoperability) and also the ability to correctly interpret the data being exchanged (semantic interoperability).

If two systems failed to exchange information properly, it means they are not clear to interpret and not easy to communicate and get proper information from each other and that might result in a failed communication which is in turn result in security flaw.

Other quality attributes strongly related (at least potentially) to interoperability is Application Programming Interface (API)

API is a software intermediary that allows two applications to communicate to each other and are necessary for systems interoperability.
