manipulate.cpp

Add a main function containing a final return statement and declaring two initialized variables

int main()

{

bool isTrue = 1 ;

int num = 255 ;

// Add more statements here.

return 0 ;

}

In the main function, insert statements to set the width and fill of an output stream, then output a text string on it

cout.width( 40 ) ;

cout.fill( ‘.’ ) ;

cout << “Output” << endl ;

Next, insert statements to set the precision of an output stream to stop truncation of decimal places – then output a floating point number showing all its decimal places

cout.precision( 11 ) ;

cout << “Pi: ” << 3.1415926536 << endl ;

Now, insert statements that use manipulators to output the variable values in modified formats

cout << isTrue << “: ” << boolalpha << isTrue << endl ;

cout << num << “: ” << hex << showbase << uppercase << num << endl ;

Save, compile, and run the program to see the output
