Depending on the format string, the function may expect a sequence of additional arguments, each containing a value to be used to replace a format specifier in the format string (or a pointer to a storage location, for n). There should be at least as many of these arguments as the numbe...
The number of arguments following theformatparameters should at least be as much as the number of format tags. The format tags follow this prototype: %[flags][width][.precision][length]specifier Wherespecifieris the most significant one and defines the type and the interpretation of the value o...

As you can see in that lastString.formatexample, that line of code doesn’t print any output, while the first line prints to standard output, and the second line prints to standard error. In the remainder of this document I’ll use Perl examples, but again, the actual format specifier s...
