How do you left justify in C++?

How do I left Align in CPP?
The left() method of stream manipulators in C++ is used to set the adjustfield format flag for the specified str stream. This flag sets the adjustfield to left. It means that the number in the output will be padded to the field width by inserting fill characters at the end.
What is iomanip in C++ with example?

How do you use left and right in C++?

What is #include Iomanip in C++?
Summary. The header is part of the Input/output library of the C++ Standard Library. It defines the manipulator functions resetiosflags() , setiosflags() , setbase() , setfill() , setprecision() , and setw() . These functions may be conveniently used by C++ programs to affect the state of iostream objects.
