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.
Find Duplicate Elements in Array in C++
#include<iostream.h> #include<conio.h> void main() { int i,arr[20],j,no; clrscr(); cout<<"Enter Size of array: "; cin>>no; cout<<"Enter any "<<no<<" num in array: "; for(i=0;i<no;i++) { cin>>arr[i]; } cout<<"Dublicate Values are: "; for(i=0; i<no; i++) { for(j=i+1;j<no;j++) { if(arr[i]==arr[j]) { cout<<"\n"<<arr[i]; } } } getch(); }
Output
Enter Size of Array : 5 Enter any 5 elements in Array: 5 4 5 2 3 Duplicate Elements are: 5
