1) What will display:

double num1, num2;

char bar = '|';

int num3;

num1 = 6;

num2 = 7.564;

num3 =12;

cout << fixed << setprecision(2);

cout << bar << setw(5) << num1 << bar << setw(5)<< num2 << bar << setw(5) << num3 << bar;

1. | 6.00| 7.56|12.00|

2. | 6.00| 7.56| 12|

3. bar 6.00 bar 7.56 bar 12.00

4. | 6.00|7.564| 12|

5. None of these, setw(5) needs to be in quotes
