Question

this program will get two integers from the user. The program will
1. call getProduct(int, int, int &); where the first two arguments
     are the two input integers and third one is the product of these 2
     integers.
2. call printEvenAscending(int, int); where the two arguments are the
     two input integers. This function will print all even numbers between
the two arguments in an ascending order. Note, the two input integers
could be in any order (such as 34, 70 or 90, 5). It is your job to
check which argument is larger.
3. call print5Rand(int, int); where the two arguments are the two input
     integers. The function will print 5 random numbers between the two
areguments(inclusive). for example. pinrt5Rand(99, 21); will print
5 random integers between 21 and 99 (inclusively).
You need complete printEvenAscending and print5Rand functions.

}

Explanation / Answer

program:--

#include <iostream>
#include <cstdlib>   //for rand() function
using namespace std;

void GetProduct ( int A, int B, int & Product );
void printEvenAscending(int, int);   //prototype
void print5Rand(int, int);   //prototype

int main()
{
   int First, Second, PROD;
  
   cout << "Input two integers ";
   cin >> First >> Second;
  
   GetProduct( First, Second, PROD );
  
   cout << PROD << endl;
  
   printEvenAscending(First, Second);   //call for even numbers
   print5Rand(First, Second);   //call for random numbers
  
   system("pause");
   return 0;
}

void GetProduct ( int A, int B, int & Product )
{
   Product = A * B;
}

void print5Rand(int a, int b)
{
   if(a>b)   //if a is big swap a,b
   {
       int temp=a;
       a=b;
       b=temp;
   }
   cout<<"5 random numbers between "<<a<<" and "<<b<<" are: "<<endl;
   for (int i=0;i<5;i++)
   {
       int num=rand() % (b-a) + a +1;   //generate a random number between a and b (inclusively)
       cout<<num<<" ";   //print number
   }
   cout<<endl;
}

void printEvenAscending(int a, int b)
{
   if(a>b)   //if a is big swap a,b
   {
       int temp=a;
       a=b;
       b=temp;
   }
   cout<<"even numbers between "<<a<<" and "<<b<<" are: "<<endl;
   for (int i=a+1;i<b;i++)   //list numbers between a and b
       if(i%2==0)   //check if number divisible by 2 or not   for check even
           cout<<i<<" ";   //if divisible print number
   cout<<endl;
}

output1:--

Input two integers 34 70
2380
even numbers between 34 and 70 are:
36 38 40 42 44 46 48 50 52 54 56 58 60 62 64 66 68
5 random numbers between 34 and 70 are:
39 69 68 38 51

output2:--

Input two integers 90 5
450
even numbers between 5 and 90 are:
6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44 46 48 50 52 54 56 58 60 62 64 66 68 70 72 74 76 78 80 82 84 86 88
5 random numbers between 5 and 90 are:
46 27 49 70 49
Press any key to continue . . .
