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.

(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]
Subject : programming
language : c++
Question :
Write c++ program and test the following functions :void multiply (float a[ ], int n, float b [ ] );The function multiplies the first n elements of a by corresponding first n elements of b. For example: if a is the array {2.2,3.3,4.4,5.5,6.6,7.7,8.8,9.9} and b is the array {4.0,-3.0, 2.0,-1.0, 0.0,0.0} Then the call multiple (a, b, 5) would transform a into the array {8.8, - 9.9, 8.8, - 5.5,0.0,7.7, 8.8,9.9}

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_forward

Whereas, number of rows would be fixed but make number of columns variables. To do this, instead of using arrays of fixed column size allocated on stack, you will make each element of array to have nColumns (passed as argument to the function) elements and store them on heap using new operator. Next, initialize the values of these arrays randomly using for loop and ptr. Finally display the sum of each individual array.You are not allowed to access the array using original variable name. (b) In the previous task we make number of columns of a 2D matrix variables. Here we will make number of rows variables as well. Thus we will have a way of defining a generic 2D matrix according to user choice. Now your goal is to write a function that receives three arguments: (i) an alias to a 2D pointer; (ii)number of rows; and (iii) number of columns; Now your goal is to first allocate the memory for rows and then for columns dynamically using new…arrow_forward
