Question

5. From a user point of view the following code snippets give the same results. What are the names given to the two different methods and which C++ standards, historically, introduced the methods.

(a) int numbers[10];

cout << "Enter ten integers: ";

for (int i = 0; i < 10; i++)

{

cin >> numbers[i];

}

// Sorting the array

sort( numbers, &numbers[10], [ ](int x, int y){ return x < y; } );

(b) int intcompare(const void *p1, const void *p2)

{

int i = *((int *)p1);

int j = *((int *)p2);

return (i < j) ;

}

.

.

int numbers[10];

cout << "Enter ten integers: ";

for (int i = 0; i < 10; i++)

{

cin >> numbers[i];

}

qsort((void *)numbers, 10, sizeof (int), intcompare);

Explanation / Answer

The two methods gives the Sorted Array as the output.

The first method is a Generic call to a Sorting method.

The comparision code is completely specified in the definition itself.

Whereas the second method is a specific call to Quick Sort method.

The comparision method definition and implementation is separated.
