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.

1)  Consider an integer array a of length n with indexing starting at 0, where n is a positive integer.If the elements of array a are to be written out in reverse order, which of the following C++ code fragment does NOT do the job?   Question options:   a.    int i=n-1;               while (i>=1){cout << a[i] << endl; i = i-1;}                cout << a[i] << endl;   b.    int i=n-1;               while (i>=1){cout << a[i] << endl; i = i-1;}   c.    int i=n-1;               while (i>=0){cout << a[i] << endl; i = i-1;}   d.    int i=n;               while (i>0){cout << a[i-1] << endl; i = i-1;}   2) Assume we use 8-bit cell to store floating point numbers, 1 bit for sign, 3 bits for excessed exponent, and 4 bits for significand.

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}
I 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. Please notice…
