Question

Use the techniques for generating random numbers and use for loops to process the indicated arrays. Develop a program that does the following:

1. Create and display an array, x, of fifty integers, i, selected at random from the range 0 <= i < 20.

2. Create and display an array, y, of fifty integers, j, selected at random from the range 0 <= j < 20.

3. Compute and display an array, a, that contains the integers which appear in x and not y. 4. Compute and display an array, b, that contains the integers which appear in y and not x. The arrays a and b should not contain any duplicates.

Explanation / Answer

#include<bits/stdc++.h>
using namespace std;

void RemoveDup(int *a, int& n)
{int i,j,k;
for(i=0;i<n;++i)
for(j=i+1;j<n;)
{
if(a[i]==a[j])
{
for(k=j;k<n-1;++k)
a[k]=a[k+1];
  
--n;
}
else
++j;
}
}
int main(int argc, char const *argv[])
{
   int x[50],y[50];

srand(time(0));
   for (int i = 0; i < 50; ++i)
   {
       x[i]=rand()%20+0;
   }
   for (int i = 0; i < 50; ++i)
   {
       y[i]=rand()%20+0;
   }

   int a[50],b[50];
   int c=0;

   for (int i = 0; i < 50; ++i)
   {
       int n=x[i];
       int j;
           for ( j = 0; j < 50; ++j)
           {
               if(n==y[j])
                   break;
           }

           if(j==50)
               a[c++]=n;
   }
   RemoveDup(a,c);
   cout<<"Array is a is ";
   for (int i = 0; i < c; ++i)
   {
       cout<<a[i]<<" ";
   }

c=0;
   for (int i = 0; i < 50; ++i)
   {
       int n=y[i];
       int j;
           for ( j = 0; j < 50; ++j)
           {
               if(n==x[j])
                   break;
           }

           if(j==50)
               b[c++]=n;
   }

   RemoveDup(b,c);
   cout<<" Array is b is ";
   for (int i = 0; i < c; ++i)
   {
       cout<<b[i]<<" ";
   }
   return 0;
}
