Thanks in Advance

#include <string>
#include <iostream>
#include <iomanip>

using namespace std;

int main()
{
string Name;
string NationalInsurenceNumber;
string RateOfPay;
string TotalHoursWorked;

float HoursWorked;
const float BasicHours = 35;
float PayRate;

int BasicHours = 35;
int BasicPay = BasicHours * PayRate;
int OvertimeHours = TotalHoursWorked - BasicHours;
int OvertimePay = PayRate * 1.5 * OvertimeHours;
int GrossPay = BasicPay + OvertimePay;

cout << "Welcome! Please Fill In the Following Details." << endl;
cout << "Name:";
cin >> setw(20) >> Name;

cout << "NationalInsurenceNumber:" << endl;
cin >> setw(12) >> NationalInsurenceNumber;

cout << "PayRate:" << endl;
cin >> PayRate;

cout << "TotalHoursWorked:" << endl;
cin >> HoursWorked;

if (HoursWorked > 35) {

float OverTime1 = HoursWorked - BasicHours;
cout << "OverTimeAmount:" << OverTime1 << endl;

float multi = OverTime1 + BasicHours;
cout << "HoursDone:" << multi << endl;

float GrossPay = PayRate*multi;
cout << "GrossPayIs:" << GrossPay << endl;

system("pause");

}

if (HoursWorked > 35) {
cout << "HoursWorked:" << HoursWorked << endl;

float GrossPay1 = PayRate*HoursWorked;
cout << "GrossAmount:" << GrossPay1 << endl;
system("pause");

}

return 0;

PayRate is undefined when you multiply for BasicPay. Same with HoursWorked.

Maybe you want to ask for them first, and then use those values for the operation.
