Array and Loop for Paycheck

[SHWOO]

I'm trying to create the code for a paycheck program where I am paid double time for anything over 10 hours, time and a half for 8-10 hours and straight time for 0-8 hours. For some reason the pay isn't accumulating correctly. Any help would be appreciated.

#include <iostream>
using std::cout;
using std::cin;

#include <iomanip>
using std::endl;


int main()
{
    double Array[13];
    double pay = 0;
    double payRate = 19.52;

    for (int i = 0; i <= 12; i++)
        Array[i] = 0;

    for (int j = 1; j <= 12; j++)
    {
        cout << "Enter hours for day " << j << endl;
        cin >> Array[j];
    }

    for (int k = 1; k <= 12; k++)
    {
    if (Array[ k ] > 10)
        pay = ((payRate * 2 * (Array[ k ] - 10)) + (payRate * 1.5 * 2) + (payRate * 8));
    else if (Array[ k ] > 8)
        pay = ((payRate * 1.5 * (Array[ k ] - 8)) + ( payRate * 8));
    else if (Array[ k ] >= 0)
        pay = payRate * 8;
    else cout << "Hours entered incorrectly, Please try again!\n" << endl;
    pay += pay;
    }
    cout << pay;
    return 0;
}

Shouldn't your second for loop be like this?

for (int j = 0; j <= 12; j++)
    {
        cout << "Enter hours for day " << j+1 << endl;
        cin >> Array[j];
    }

It might be easier to accumulate the pay with

set totalpay to hours * straighttime       // this will include ALL hours worked
subtract 8 from hours to get all overtime  // time+half and double
add to totalpay hours * time-and-a-half    // IOW 1/2 of straighttime
subtract 2 from hours to get all doubletime 
add to totalpay hours * time-and-a-half    //another 1/2 of straighttime
                                           // 2 halves = one whole

I am a novice programmer and I didn't think of that. Is it better or more common to do it that way?

I just skipped the zeroeth subscript so the first workday would be 1

Yes, it's more common to actually use the 0th element. If you need 12 elements, it makes less sense to define 13 of them. Especially in the case of a structure that might be -- say -- 1000 total bytes. A big waste of space.
