Question

 17.True or False: Algorithms should be specified in pseudocode before they are implemented in C. 

 18. True or False: In C, false is defined as any result that is zero.

 19. True or False: An advantage to defining functions in C is that they may be reused in other projects.

 20. True or False: Suppose a function main calls a function f. As a parameter to f, main passes a pointer p to a struct. Further suppose that f's body modifies p by pointing it to a different struct. When f returns, the pointer passed by main will also be pointing to a different struct.

 21. True or False: An identifier/variable name, in C, may start with a digit.

 22. True or False: Preprocessor directives are handled during compilation.

 23. True or False: The control expression of a switch-case statement in C can be of type enum. 24. True or False: Assume that a character pointer cptr points to a character array carrax of size 10. The following expressions are equivalent: *carray[2] and *(cptr + 2).

 25. True or False: In C, you can assign an array of character pointers to point to specific addresses, i.e.

 char *array[10], var;

 array[5] = &var;

 26. True or False: We use the debugger to find logic errors.

 27.True or False: In C, arrays and pointers are essentially interchangeable-you can use always use pointer notation for arrays and always use array notation for pointers.

 28. True or False: In C, when an array is passed to a function, only the address of the zeroth element is passed to the function.

 29. True or False: An actual argument is the argument that we pass into a function when it is called, i.e. my function ('a'), where 'a' is the actual argument.

 30. True or False: The following is an example of a sentinel-controlled loop:

 while (my array[i] - '\0')

Answer 1

17:-True

Reason:- Algorithm is just a graphical representation

18:-False

Reason:- False is a Boolean data type

- Zero is a Int data type.

19:- True

Reason:- User defined functions may be used again and again. Functions are used to perform the same operation infinite number of times.

20:- True

Reason:- As the pointer will point to the element based on function f.

21:- False

Reason:- When we declare the variable we cannot be started with a digit it is only started with a alphabet.

It is a inbuilt rule made by the developers

22:- True

Reason:- Pre-proccessor directive run when the source code compiled.

23:- False

Reason:- Enum can only be declared using namespace.

24:-False

Reason:- Pointer and Array are differnent concepts

25:-True

Reason:- Pointer and Array are differnent concepts

26:- False

Reason:- debbuggers are used to find syntatical errors

27:- False

Reason:- pointer and array are differnent concepts

28:- False

Reason:- The Array is passed to the function

29:- False

Reason:- Actual argument are the argument that are passed in main function.

30:- True

Reason:- Because we does not know the ending point of the loop.
