Question

DO IN C++

Write a function that will generate an array of random numbers. It needs to:

Take 3 integers as parameters

-The first is the minimum value

-the second is the maximum value

-the third is the size of the new array

-create a dynamically allocated array of the correct size

-generate a random number (between min and max) for each element in the array

-return a pointer to the array

Create a main() function that tests the above function and displays the values in the random array.

Answer 1

C++ Program:

/* C++ Program that generates an array of random numbers */

#include
#include

using namespace std;

//Function prototype
int* generate(int, int, int);

//Main function
int main()
{
    //Pointer array
    int* randomArray;
    int i;

    //Initializing random value
    srand(time(NULL));

    //Generating random array and storing result
    randomArray = generate(6, 23, 10);

    cout << "\n\n Values in the Array: \n";

    //Printing elements in the random array
    for(i=0; i<10; i++)
        cout << " \t " << randomArray[i];

    cout << endl << endl;
    return 0;
}

//Function that generates an array of random values
int* generate(int min, int max, int size)
{
    int* arr;
    int i;

    //Allocating memory
    arr = new int[size];

    //Generating a random number and storing value in the array
    for(i=0; i         *(arr+i) = min + rand() % (max - min + 1);

    //Returning pointer array
    return arr;
}
