Manipulators in C++

They are operators that are used for formatting display.

e.g. endl, setw(), setprecission(), etc.
"endl" can be directly used in a program. For other manipulators, we have to include header file "iomanip.h".

endl:
--> end of line.
--> To bring cursor to next line.
--> same as command "\n".

setprecission() --> To set the numbers to be displayed after the decimal point.
Syntax: setprecission(5) --> displays 5 digits after the decimal point.

setw() --> To set width of data to be printed.

Sample program:

#include < iostream.h > #include < iomanip.h > void main() { int a=5,b=6; cout << a << b << endl; cout << setw(5)<< a << b < cout << setw(5)<< a << setw(6)<< b << endl; } 56 56 5 6
