CS 159 Lab 5 True or False
A structure chart should be created after your program has been written.
.F
A function that passes at least one parameter by address must pass them all by address.
F
All functions that utilize pass by address must be void functions.
F
Each rectangle on a structure chart represents the user-defined and standard library functions used in a program.
F
It is never possible to determine if any parameters are passed to a function by address from an example call to the function.
F
With the use of pass by address it is now permissible for a function to be written to complete several subtasks of the program.
F
A function that does one and only one process is functionally cohesive.
T
A function that passes at least one parameter by address does not pass them all by address.
T
A structure chart may show the data that is exchanged between functions.
T
A structure chart should be created before your program has been written.
T
A variable declared in the local declaration section of a function has a scope that extends until the end of that function.
T
All functions that utilize pass by address may not always be void functions based on whatever value the user wants to be returned (it could be a different variable being returned and not the one being passed by address).
T
Each rectangle on a structure chart represents the user-defined functions used in a program.
T
Functional cohesion is a measure of how closely the processes in a function are related.
T
Given the address of a variable the called function can access and manipulate the value of a variable in the calling function.
T
In downward communication (passing by value) it is only a copy of the data that is sent from the calling function to the called function.
T
It is a good design practice to design a user-defined function such that it is testable apart from the rest of the program.
T
It is a good design practice to limit user-defined functions to only a single task.
T
It is a good design practice to not repeat the logic of one function in other functions of the program.
T
It is not possible to access a variable in the calling function by its identifier when inside the called function.
T
It is poor programming style to reuse identifiers within the same scope.
T
It is possible to determine if any parameters are passed to a function by address based on the first line of the definition of the function (also known as the function header).
T
It is possible to determine if any parameters are passed to a function by address from an example call to the function using the address operator.
T
It is possible to determine if any parameters are passed to a function by address from the declaration statement of the function.
T
No code is contained in a structure chart as it only demonstrates the function flow of the program.
T
Objects with a global scope are visible (defined) everywhere in the program.
T
One benefit of pass by address is that it allows multiple changes to be made in a function and to have those changes available in the calling function.
T
The * and & operators are inverse operations of each other.
T
The asterisk (*) when used in a variable declaration indicates that such variables are not data variables but address (pointer) variables which can store the addresses of other variables in the program.
T
The asterisk has two different uses, declaring an address variable (pointer) and indirectly accessing the data (in the memory location to which the variable points).
T
The called function must declare a special type of variable known as a pointer to store a memory address that is sent from the calling function.
T
The scope of an object determines the region of the program in which it is visible (and defined).
T
To obtain the address of a variable use the address operator (&).
T
When only one data item needs to be returned to the calling function then we should use the standard return statement rather than passing a single parameter by address.
T
When working with a parameter that has been passed by address it is unnecessary to use the & (address) operator in the scanf because the parameter already represents a memory location.
T
With the use of pass by address it is still not permissible for a function to be written to complete several subtasks of the program.
