Ask your self questions can help you think of what to measure, in order to get answers.
The question above has multiple choices as follows;
a. API
b. docstring
c. help
d. man
Well, I am stuck between B and C. I’ll however settle for (B) docstring.
Python docstrings provide an easier way to associate
documentation with python classes, modules and functions. The interactive help function
on the other is built in and is intended for interactive use. This function
exists to view help interactively. With the help feature, you can quickly learn
classes, modules, functions and many more.
Answer:
cout << setprecision(2)<< fixed << number;
Explanation:
The above statement returns 12.35 as output
Though, the statement can be split to multiple statements; but the question requires the use of a cout statement.
The statement starts by setting precision to 2 using setprecision(2)
This is immediately followed by the fixed manipulator;
The essence of the fixed manipulator is to ensure that the number returns 2 digits after the decimal point;
Using only setprecision(2) in the cout statement will on return the 2 digits (12) before the decimal point.
The fixed manipulator is then followed by the variable to be printed.
See code snippet below
<em>#include <iostream> </em>
<em>#include <iomanip>
</em>
<em>using namespace std; </em>
<em>int main() </em>
<em>{ </em>
<em> // Initializing the double value</em>
<em> double number = 12.3456; </em>
<em> //Print result</em>
<em> cout << setprecision(2)<< fixed << number; </em>
<em> return 0; </em>
<em>} </em>
