Need help shifting array 2 spaces to the left.

[DARK BUGABOO]

My code lets a user input how big they want an array to be then it reverses it. My professor wants us to shift the element 2 spaces to the left. So if someone entered 12345 into the array my code spits out 54321. Our Professor then wants us to shift the code 2 spaces to the left so my code would then spit out 32154
I asked my professor for help and he said

save the first number to int x;
save the second number to int y;
shift everything 3 positions to the left.
assign y to the last element in the array
assign x to the element next to last.
But Im not quite understanding how to put this into my code

  #include <iostream>

using namespace std;

int main()
{
    int N;          // This will be the number the user enters for size of array
    char choice;        // Choice on if they wish to select another array
    cout << "This is an array manipulation program" << endl;
    cout << "\nEnter the size of the array ";
    cin  >> N;
    char array[N];  // This is the array that will store all the inputs
    do
    {
    cout << "\nEnter any " << N << " Characters, Digits, or Special Symbols : ";
    for(int i=0; i <N; ++i)
    {
    cin>>array[i];
    }
    cout << "\n\nThe array contains the following   :   ";

    for(int i=0; i<N; i++)
    {
        cout<<array[i];
    }
    cout << endl;
    bool CapitalExists=false;       // this checks if Capital Letters Exist
    bool lowerExists=false;         // This checks if small letters exist
    bool digit=false;               // This checks if the input is a digit
    bool special=false;             // This checks if the input is a special symbol
    for(int i=0; i<N; i++)
    {
       if (array[i]>= 'A' && array[i]<= 'Z')
         {
             CapitalExists=true;
             cout << array[i] << "  is a Capital Letter" <<endl;

         }

     cout << "\n\n\nThe array in reverse order  ";

    }
    cout << "\n\nThe array after rotating 2 position to the left       " << endl;
    int x = array[0];       // Int x is the first number to be shifted
    int y = array[1];       // Int y is the second number to be shifted

    cout << "\n\nWould you like to check for another array?"
         << "\nEnter Y or y for Yes \nOR\nN or n for No -------> ";
    cin  >> choice;

There're too many irrelative code.
My idea to solve the problem is to save the first value, shift everything to the left and then overwrite the last field with saved first value. Repeat the steps to result shifting two characters.

void shift_str(char *str, int count)
{
    int i, k, t;
    
    for (i = 0; i < count; i++) {
        t = str[0];
        for (k = 1; k < strlen(str); k++) {
            str[k - 1] = str[k];
        }
        str[k - 1] = t;
    }
}
