C++ Program to print all possible subset of a set

C++ Program to print all possible subset of a set

In this example, we will see a C++ program through which we can print all the possible subset of a given set.

The total number of possible subsets a given set can have is 2^n.

where n is the number of elements present in that given set.


#include <bits/stdc++.h>
using namespace std;
void allPossibleSubset(int arr[],int n)
int  count = pow(2,n);
// The outer for loop will run 2^n times to print all subset .
// Here variable i will act as a binary counter
for (int i = 0; i < count; i++)
// The inner for loop will run n times , As the maximum number of elements a set can have is n
// This loop will generate a subset
for (int j = 0; j < n; j++)
// This if condition will check if jth bit in binary representation of  i  is set or not
// if the value of (i & (1 << j)) is greater than 0 , include arr[j] in the current subset
// otherwise exclude arr[j]
if ((i & (1 << j)) > 0)
cout << arr[j] << " ";
cout << "\n";
int main()
int n;
cout << "Enter size of the set\n";
cin >> n;
int arr[n];
cout << "Enter Elements of the set\n";
for(int i=0;i<n;i++)
cin >> arr[i];
return 0;

Enter size of the set
Enter Elements of the set
