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.

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}
