A.
Program Plan Intro
Given C Code:
void copy_array(long *src, long *dest, long n)
{
long i;
for(i=0; i<n; i++)
dest[i] = src[i];
}
Cycles per element (CPE):
- The CPE denotes performance of program that helps in improving code.
- It helps to understand detailed level loop performance for an iterative
program. - It is appropriate for programs that use a repetitive computation.
- The processor’s activity sequencing is controlled by a clock that provides regular signal of some frequency.

Source computer sources.. 33.
(C++) I need a quicksort algorithm implementation which returns the indices of the sorted array in an array without modifying the array itself:ie,Before sortingindex : 0 1 2 3 4 5values: 70 60 40 20 30 50After sortingindex : 3 4 2 5 1 0values: 70 60 40 20 30 50
function returns an array with indexes: [3 4 2 5 1 0]

- Need help with example 7 in c++ please and thank youarrow_forwardI have a question about programming in C(89) C. Could someone please show me how to make a program that uses a custom function that rearranges array elements from one array of size n into a new larger second array of size (n+1) and places a new element into the new second larger array at a particular index location? For example, the user would be prompted for a size like say, 7. Then the user would be prompted for the seven array element values, which could be like {1, 7, 4, 6, 3, 9, 8}. Then the user gets prompted again for a new element value to add to the new larger second array. Let's say the new value is entered as 5. All of this would be done in main and no pointers are required. Then main calls a custom function called rearrange. the prototype for rearrange must be; void rearrange(int *a, int n, int insert, int *b); After rearrange is done, main would display the contents of the new larger second array like so; {1, 4, 3, 5, 7, 9, 8} Here's the trick though.

- ""'Question"".arrow_forwardFor each of the following problems, all functions should be implemented using a call stack. Problem 2: Write a program that defines two integer array that are pre-sorted and the same size (e.g., [3, 7, 9, 11, 15, 21] and [1, 4, 6, 14, 18, 19]) and a function merge that takes the two arrays (and their size) as inputs and populates a single array of twice the size of either input array that contains the elements of both arrays in ascending order. In the example arrays given, then output would be [1, 3, 4, 6, 7, 9, 11, 14, 15, 18, 19, 21]. Have your 'main' function (not the merge function) print out the final array using a comma as a delimiter.arrow_forwardc++ problemarrow_forward
