RAVI KUMAR you have to use
cin>>setw(50);

# include <iostream>
# include <iomanip>
# include <string>
using namespace std;

int main()
{
string label;
double price;
cout <<"\nPlease enter an article label: ";

cin >> setw(50);
cin >> label;
cin.sync();
cin.clear();
cout << "\nEnter the price of teh article: ";
cin >> price;
cout << fixed << setprecision(2)
<< "\nArticle:"
<< "\n Label: " << label
<<"\n Price: " << price << endl;
return 0;
}

This way it will execute correctly else setw() will give error
The setw() method of iomaip library in C++ is used to set the ios library field width based on the width specified as the parameter to this method.

Syntax:

setw(int n)
