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 />
The line code will create array is G = array('f',[2.5, 3, 7.4])
<h3>What is meant by array ?</h3>
As opposed to defining distinct variables for each value, arrays are used to hold numerous values in a single variable. Set the data type (such as int) and the array name, followed by square brackets [, to construct an array.
An array is a collection of elements with the same type that are kept in nearby memory locations and may each be separately referred to using an index to a special identifier. There is no need to declare five distinct variables when declaring an array of five int values (each with its own identifier).
In the C programming language, arrays are a derived data type that may contain primitive data types like int, char, double, float, etc.
