Causes text that is not as wide as the output width to appear in the stream flush with the left margin.
ios_base& left(
ios_base& _Str
);
Parameters
- _Str
A reference to an object of type ios_base, or to a type that inherits from ios_base.
Return Value
A reference to the object from which _Str is derived.
Remarks
The manipulator effectively calls _Str.setf(ios_base::left, ios_base::adjustfield), and then returns _Str.
Example
// ios_left.cpp
// compile with: /EHsc
#include <iostream>
int main( )
{
using namespace std;
double f1= 5.00;
cout.width( 20 );
cout << f1 << endl;
cout << left << f1 << endl;
}
