? Usability and usability inspection
methods
Usability means easy to learn, effective to use
and provide an enjoyable experience. Usability
inspection methods include;
? Heuristic Evaluation: A small team of
evaluators inspects an interface using a
small checklist of general principles and
produces an aggregate list of potential
problems.
? Guideline Checking: An evaluator
checks an interface against a detailed
list of specific guidelines and produces a
list of deviations from the guidelines.
? Cognitive Walkthrough: A small team
walks through a typical task in the
mindset of a novice user and produces a
success or failure story at each step
along the correct path. (analyses
learnability)
? Guideline Scoring: An evaluator scores
an interface against a detailed list of
specific guidelines and produces a total
score representing the degree to which
an interface follows the guidelines.

Create a function in C++ called order() that takes two integer reference parameters. If the first argument is greater than the second argument, reverse the two arguments. Otherwise, take no action. That is, order the two arguments used to call order() so that, upon return, the first argument will be less than the second. For example, given
int x=1, y=0;
order(x, y);
following the call, x will be 0 and y will be 1.

Create a function called reverse() that takes two parameters. The first parameter called str, is a pointer to a string that will be reversed upon return from the function. The second parameter is called count, and it specifies how many characters of str to reverse(). Give count a default value that, when present, tells reverse() to reverse the entire string.(use C++ language)

Given the class below,
class three_d{
int x, y, z;
three_(int i, int j, int k)
{
x = i; y = j; z = k; }
three_() {x=0; y=0; z=0; }
void get(in int &j, int &k){
i = x; j = y; k = z;}
};
Rewrite it so that it uses reference parameters to the operator functions.

Given the following class declaration;
class dynarray {
int *p;
int size;
public:
dynarray(int s);
int &put(int i);
int get(int i);
//create operator=( function
};
fill in all the details that will create a dynamic array type. That is, allocate memory for the array, storing a pointer to this memory i p. Store the size of the array, in bytes, in size. Have put() return a reference to the specified element, and have get() return the value of a specified element. Dont allow the boundaries of the array to be overrun. Also, overload the assignment operator so that the allocated memory of each array is not accidentally destroyed when one array is assigned to another.
