Specifies that integer variables appear in base 10 notation.
ios_base& dec(
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
By default, integer variables are displayed in base 10.
dec effectively calls _Str.setf(ios_base::dec, ios_base::basefield), and then returns _Str.
Example
// ios_dec.cpp
// compile with: /EHsc
#include <iostream>
int main( )
{
using namespace std;
int i = 100;
cout << i << endl; // Default is base 10
cout << hex << i << endl;
dec( cout );
cout << i << endl;
oct( cout );
cout << i << endl;
cout << dec << i << endl;
}
