C++ program to find the integers which come odd number of times in an array

In this example, we will see a C++ program through which we can find the integer which comes an odd number of times in a given array.

Program:


#include <iostream>
#include <vector>
using namespace std;

//function to find odd integer
int oddInteger(vector <int> a) 
{
int result=0;
for(unsigned int i=0;i<a.size();i++)
{
result=result^a[i];        
}
return result;    
}

//main function to test code
int main() {
int n;
//input total number of elements
cin >> n;
vector<int> a(n);

//read n numbers
for(int i=0;i<n;i++)
{
cin>>a[i];
}

//find and print result
int result = oddInteger(a);
cout << result << endl;

return 0;
}

Output:
9
2
5
7
1
85
23
11
54
14
112
