The representation of the + (plus sign) depends on whether the+or space-character formatting option is specified. These subroutines can handle a format string that enables the system to process elements of the parameter list in variable order. In such a case, the normal ...
printf( "%i + %i = %i\n", 2, 3, (2+3) ); will produce the following output (by converting the three integer arguments to strings using default formatting): 2 + 3 = 5 The following table shows the different format letters you can use withprintf. Each letter corresponds to a differe...
