You can iterate over them in a loop
if( strcmp(str, arr[i]) == 0 )
0

for (int i = 0; i
{
    if (userInput == arr[i])
    {
        cout << userInput << " is in the array at position " << i << endl;
    }
    else
    {
        cout << userInput << " is not in the array at position " << i << endl;
    }
}
below code is to find dublicate , if you want to compare each element of array to other element of same array
void printDuplicates(vector<string> words)
{
    unordered_set<string> s;

    bool dupFound = false;
    for (int i = 1; i
    {
        if (s.find(words[i]) != s.end())
        {
            cout << words[i] << endl;
            dupFound = true;
        }
        else
            s.insert(words[i]);
    }

    if (dupFound == false)
        cout << "No Duplicate words" << endl;
}

// Driver code
int main()
{
    vector<string>words{ "welcome", "to", "Jungle",
                                  "for", "jungle" };
    printDuplicates(words);
    return 0;
}
