Write a program that calculates a car's gas mileage. The program should ask the user to enter the number of gallons of gas the car can hold and the number of miles it can be driven on a full tank. It should then display the number of miles than may be driven per gallon of gas.

int num1 = 2897,

// Required for setw
num2 = 5,
num5 = 7,
num8 3456,
// Display the first row of numbers
cout<<setw(6) << num1 <<setw(6)
<< num2 <<setw(6) << num3 << endl;
num3 = 837,
num6 1623,
num9 = 12;
// Display the second row of numbers
cout<<setw(6) << num4 <<setw(6)
Program Output
2897

390 3456
<< num5 <<setw(6) << num6 << endl;
5 837
7 1623
12
// Display the third row of numbers
cout<<setw(6) << num7 <<setw(6)
<< num8 <<setw(6) << num9 << endl;
return 0;
By printing each number in a field of 6 positions, they are displayed in perfect columns.
NOTE: A new header file, <iomanip>, is included in Program 3-13. It must be used
in any program that uses setw.
Notice how a setw manipulator is used with each value, because setw only establishes a
field width for the value immediately following it. After that value is printed, cout goes
back to its default method of printing.
You might wonder what will happen if the number is too large to fit in the field, as in the
following statement:
value = 18397;
cout<<setw(2) << value;
In cases like this, cout will print the entire number. setw only specifies the minimum num-
ber of positions in the print field. Any number larger than the minimum will cause cout to
override the setw value.
