c Writes a single character. The argument is first converted to unsigned char. If the l modifier is used, the argument is first converted to a character string as if by %ls with a wchar_t[2] argument. N/A N/A int wint_t N/A N/A N/A N/A N/A s Writes a cha...
to a hexadecimal number, expressed as another string, it's fiddly and, except as a learning exercise, pointless thing to do. sprintf converts C variables to human-readable strings for you. To get a decimal, pass "%d", to get hex, pass "%x". You also need to pass a destination buffe...
Theprintffunction formats a series of strings and numeric values and builds a string to write to the output stream using theputcharfunction. Thefmtstrargument is a format string that may be composed of characters, escape sequences, and format specifications. ...
The snprintf subroutine is identical to the sprintf subroutine with the addition of the Number parameter, which states the size of the buffer referred to by the String parameter. The wsprintf subroutine converts, formats, and stores the Value parameter values, under control ...
+ Prefix the output value with a + or - sign if the output is a signed type. blank (’‘) Prefix the output value with a blank if it is a signed positive value. Otherwise, no blank is prefixed. Prefixes a non-zero output value with 0, 0x, or 0X when used with o, x, and ...
