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 number...

For example, if the format specifier is %F instead of %f, an infinity is formatted as INF instead of inf. The scanf functions can also parse these strings, so these values can make a round trip through printf and scanf functions.Before Visual Studio 2015, the CRT used a different...
The %#p format specifier has much better performance than the %p format specifier. See theILE C/C++ Programmer's Guidefor more information about using IBM i pointers. If a floating-point value of INFINITY or Not-a-Number (NaN) is formatted using the a, e, f, or g format, the output...
When the LC_SYNTAX category is set using setlocale(), the format strings passed to the printf() functions must use the same encoded character set as is specified for the LC_SYNTAX category. The # flag should not be used with c, lc, C, d, i, u, s, or p conversion specifier. Outpu...
