C++ Program to Find Duplicate Elements in Array



C++ Program to Find Duplicate Elements in Array

Array is the collection of similar data type, In this program we find duplicate elements from an array, Suppose array have 3, 5, 6, 11, 5 and 7 elements, in this array 5 appear two times so this is our duplicate elements.

#include<iostream.h>
#include<conio.h>

 void main()
 {
  int x,arr[20],j,no;
  clrscr();
  cout<<"Enter Size of array: ";
  cin>>no;
  cout<<"Enter any "<<no<<" num in array: ";
  for(x=0;x<no;x++)
  {
   cin>>arr[x];
  }
  cout<<"Dublicate Values are: ";
  for(x=0; x<no; x++)
   {
    for(j=x+1;j<no;j++)
    {
    if(arr[x]==arr[j])
    {
    cout<<"\n"<<arr[x];
    }
   }
   }
  getch();
 }

Strrchr searches the string in reverse order
'StrrChr' is similar to the function 'StrChr', the only difference is that it searches the string in "Reverse Order", would have understood why we have extra r in 'strrchr', yes you guessed it
