Hello, so I am new to coding and wanted to use VS Code to code in C++, so I installed it, installed C/C++ IntelliSense v0.12.4 and followed instructions on the VS Code website to make a c_cpp_properties.json file and copied the code into it like they said. When I open my .cpp project that I had made in notepad++, I get the error: "

include errors detected. Please update your includePath. IntelliSense features for this translation unit (directory\file.cpp) will be provided by the Tag Parser. (9, 1)

cannot open source file "iostream" (9, 1)"

My .cpp code `

include

using namespace std;

int main() { string firstName, lastName; double hourRate, numHours;

    cout << "+----------------------------------------+" << endl;
    cout << " Your first name and last name: ";
    cin >> firstName >> lastName;
    cout << " Your hourly rate: ";
    cin >> hourRate;
    cout << " Number of hours worked last week: ";
    cin >> numHours;
    cout << endl;
    double regPay, overTPay, gPay, socSec, med, netPay;
    if (numHours <= 40)
    {
        regPay = hourRate * numHours;
        gPay = regPay;
        overTPay = 0;
    }
        else
        {
            double oTHours;
            oTHours = numHours - 40;
            regPay = hourRate * (numHours - (numHours - 40));
            overTPay = (hourRate * 1.5) * oTHours;
            gPay = regPay + overTPay;
        }
    socSec = gPay * 0.062;
    med = gPay * 0.0145;
    netPay = gPay - (socSec + med);
    cout << "+----------------------------------------+" << endl << endl;
    cout << " Pay Stub\n" << " Regular pay  $" << regPay << endl;
    cout << " Overtime pay $" << overTPay << endl;
    cout << " Gross pay    $" << gPay << endl;
    cout << " Social Sec.  $" << socSec << endl;
    cout << " Medicare     $" << med << endl;
    cout << " Net Pay      $" << netPay << endl << endl;
    cout << "+----------------------------------------+" << endl << endl;
    cout << " Pay to: " << firstName << " " << lastName << endl;
    cout << " Total Pay: $" << netPay << endl << "\t\t\t   ";
    cout << "Signed: P inc." << endl;
    cout << "+----------------------------------------+" << endl;
    return 0;

Also, when I hover over the "" this shows up: "
