29.9. Printing with Field Widths and Precisions
The exact size of a field in which data is printed is specified by a field width. If the field width is larger than the data being printed, the data will be right justified within that field by default. (We demonstrate left justification in Section 29.10.) The programmer inserts an integer representing the field width between the percent sign (%) and the conversion character (e.g., %4d) in the format specifier. Figure 29.12 prints two groups of five numbers each, right justifying those numbers that contain fewer digits than the field width.
