见MSDN:
d Decimal integer. Pointer to int.
i Decimal, hexadecimal, or octal integer. Pointer to int.
o Octal integer. Pointer to int.
u Unsigned decimal integer. Pointer to unsigned int.
x Hexadecimal integer. Pointer to int.
e, E, f, g, G Floating-point value consisting of optional sign (+ or –), series of one or more decimal digits containing decimal point, and optional exponent (“e” or “E”) followed by an optionally signed integer value. Pointer to float.
n No input read from stream or buffer. Pointer to int, into which is stored number of characters successfully read from stream or buffer up to that point in current call to scanf functions or wscanf functions.
s String, up to first white-space character (space, tab or newline). To read strings not delimited by space characters, use set of square brackets ([ ]), as discussed following Table R.7. When used with scanf functions, signifies single-byte character array; when used with wscanf functions, signifies wide-character array. In either case, character array must be large enough for input field plus terminating null character, which is automatically appended.
S String, up to first white-space character (space, tab or newline). To read strings not delimited by space characters, use set of square brackets ([ ]), as discussed preceding this table. When used with scanf functions, signifies wide-character array; when used with wscanf functions, signifies single-byte–character array. In either case, character array must be large enough for input field plus terminating null character, which is automatically appended.

"%s",字符串型
"%f",浮点型("%5.2f":长度为5,2位小数)
"%f",浮点型("%5.2f":长度为5,2位小数)

你参照谭浩强的c程序设计的printf函数说明

"%1d"指的是整型,
"%u",长整型
"%c",字符型
"%u",长整型
"%c",字符型
