ios manipulators internal() function in C++
The internal() 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 internal. It means that the number in the output will be padded to the field width by inserting fill characters at a specified internal point.
Syntax:
ios_base& internal (ios_base& str)
Parameters: This method accepts str as a parameter which is the stream for which the format flag is affected.
Return Value: This method returns the stream str with internal format flag set.
Example 1:
#include <iostream>
using namespace std;
int main()
{
double x = -1.23;
cout.precision(5);
cout << "internal flag: " ;
cout.width(12);
cout << internal << x << endl;
return 0;
}
|
Output:
internal flag: - 1.23
Example 2:
#include <iostream>
using namespace std;
int main()
{
double x = -1.23;
cout.precision(5);
cout << "internal flag: " ;
cout.width(12);
cout << internal << x << endl;
return 0;
}
|
Output:
internal flag: - 1.23
