copy one array to another array in normal order
I don't understand how to complete these three assignments. Can someone like give me an example of something because i can't figure it out.Here are the problems in the attached section. The below question i can't seem to figure out how to do also.Â
Write a program that will have 4 functions:
-Â Â Â Â Â Â Â Â Â input an arrayÂ
               void inputData( istream &, int [], int);
-         print an array Â
               void printData( ostream &, const int [], int);
-Â Â Â Â Â Â Â Â Â copy one array to another array in normal order
                                                     void copyArray( const int orig[], int dup[], int);
NOTE:       Driver - allocate memory for both arrays. Supply the data for the 1st array. Call the copyArray functionÂ
                       int a[4] = { 7, 14, 9,10};
                       int b[4];
                       copyArray(a,b,4);
                       printData(cout,b,4);
               THE OUTPUT WILL BE:
                    7
                    14
                    9
                    10
The student should NOT create a local array inside the copyArray function. The reasons is that the local array inside the function
only exists while the function is executing. After the function returns, all of the local memory is reclaimed.
-Â Â Â Â Â Â Â Â Â copy one array to another array in reverse order
           void revCopy( const int orig[], int rev[], int);
   Write the main program to test the four functions you wrote
- #include <iostream>
using std::cout;
using std::ios;
#include <iomanip>
using std::setw;
using std::setprecision;
using std::fixed;
using std::showpoint;
#include <cstdlib>
using std::rand;
using std::srand;
#include <ctime>
using std::time;
int main()
{
   const long ROLLS = 36000;
   const int SIZE = 13;
   // array expected contains counts for the expected
   // number of times each sum occurs in 36 rolls of the dice
   /* Write the declaration of array expected here. Assign an
   initializer list containing the expected values here. Use
   SIZE for the number of elements */
   // expected[0] and expected[1] will have the value of 0
   //    since there are zero ways for two dice to add up to 0 or 1
   // expected[2] will hold 1,   1 + 1 gives 2
   // expected[3] will hold 2,   1 + 2 and 2 + 1 both gives 3
   // expected[4] will hold 3,   1 + 3 and 3 + 1 and 2 + 2 all gives 4
   int x; // first die
   int y; // second die
        /* Write declaration for array sum here. Initialize all
        elements to zero. Use SIZE for the number of elements */
  Â
  Â
        // see page 383 of the text for initializing arrays at compile time
   srand(time(0));
  Â
   // roll dice 36,000 times
   /* Write a for loop that iterates ROLLS times. Randomly
   generate values for x (i.e., die1) and y (i,e, die2)
   and increment the appropriate counter in array sum that
   corresponds to the sum of x and y */
   cout << setw(10) << "Sum" << setw(10) << "Total" << setw(10)
      << "Expected" << setw(10) << "Actual\n" << fixed << showpoint;
   // display results of rolling dice
   for (int j = 2; j < SIZE; j++)
      cout << setw(10) << j << setw(10) << sum[j]
      << setprecision(3) << setw(9)
      << 100.0 * expected[j] / 36 << "%" << setprecision(3)
      << setw(9) << 100.0 * sum[j] / 36000 << "%\n";
   return 0; // indicates successful completion
} // end main//Â Â Complete the following program
//Â Â Â Â Â Â Â Â Â Â The program generates 500 numbers between 1 and 6 and stores
//Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â them in an array
//Â Â Â Â Â Â Â Â Â Â The program loops and counts how many times each number occurs
#include <iostream>
#include <cmath>
using namespace::std;
void generateData(int[], int count);
int countValue(const int[], int howMany, int value);
void main()
{
   int data[1000];
   generateData();    //  call the function to generate 500 numbers
                  // between 1 and 6
                  //  store the values in the data array
   for (int i = 1; i <= 6; i++)
   {
      cout << i << " " << countValue() << endl; // call the
                                      //countValue function
   }
}
void generateData(int d[], int cnt)
{
   srand(12345);
   int dice;
   for (int i = 0; i < cnt; i++)
   {
      dice = ;    // generate a random number between 1 and 6
      d[i] = dice;
   }
}
int countValue(const int d[], int howMany, int value)
{
   int total = 0;
   for (int i = 0; i < howMany; i++)
   {
      if ()        // adjust the total if number in cell i is
         ;     //    equal to the parameter value
   }
   return total;
