List three of parametric manipulators that you learned to format the output c. What is the signature of the setprecision function? d. What is the signature of the setw function?

Explanation / Answer

parametric manipulators that we used are:

setf

endl sends a newline character

setw manipulator will helps insets the width of the filed assigned for the output

setprecision manipulator sets the total number of digits that can be displayed,floating point numbers are printed.

Manipulator endl setw setprecision

setf

endl sends a newline character

setw manipulator will helps insets the width of the filed assigned for the output

setprecision manipulator sets the total number of digits that can be displayed,floating point numbers are printed.

  signature of setprecision function  

  setprecision([number_of_digits]);  

  signature of setw function  setw([number_of_characters]);      setfill([character]);
