How can fix error C2001: newline in constant
#include<iostream>
#include<iomanip>
using namespace std;
int main()
{
int a = 40;
double wage_per_hour = 6.50;
double weekly_sales;
double percent_sales = 0.1;
double percent = 0.15;
float total_pay1;
float total_pay2;
char again;
cout.setf(ios::fixed);
cout.precision(5);
do
{
cout<<"please enter the expected weekly sales n";
cin >> weekly_sales;
total_pay1 = (a * wage_per_hour)+(percent_sales * weekly_sales);
total_pay2 = (weekly_sales * percent);
cout <<"The amount of money you will receive if you take payment
<< "plan A is" << total_pay1
<<"The amount of money you will receive under payment plan B is"
<< total_pay2 << "n";
cout << "Do you want to run this program again? (y/n)";
cin >> again;
cout << endl;
}
while (again=='Y'|| again=='y');
cout<<"Goodby!n";
return 0;
}
