Answer:

dataFile << salary;

Explanation:

To write salary to a file (payroll.dat) using ofstream, you make use of the following instruction:

<em>ofstream dataFile; </em>

<em>myfile.open ("payroll.dat"); </em>

<em>myfile <<salary; </em>

<em>myfile.close();</em>

<em />

This line creates an instance of ofstream

<em>ofstream dataFile; </em>

This line opens the file payroll.dat

<em>myfile.open ("payroll.dat"); </em>

This is where the exact instruction in the question is done. This writes the value of salary to payroll.dat

<em>myfile <<salary; </em>

This closes the opened file

<em>myfile.close();</em>

<em />

<em />

      }

  }

}

Explanation:

  • Inside the action performed method, pass the strings in text box.
  • check if the value has been modified then do the relevant conversions inside the conditional statement.
  • When the user clears, it will not do to the inch conversion.
