Formatting Output

• the C++ i/o library provides a number of utility functions
  • #include <iomanip>
  • setw (int)
    • For non character data (strings, int, float)
    • Controls the width of the output field
    • Describes the minimum number of characters to be printed
    • For Right Justified output
    • cout << setw(7);
    • This will cause the next item output to be at least seven spaces wide, padded with blank spaces if necessairy.
  • fixed, scientific
    • All floating point output is in (fixed, scientific) format
    • cout << fixed;
    • Until changed
  • showpoint, noshowpoint - floats print with decimal point showing.
  • setprecision (n) - n is the number of decimal places to show.
• Note : these will not work on cslab103, but will work on the new slackware distributions (on the laptop)
