正如前面提到的, 进入 printf 后, 函数基本上对传入的参数一无所知,需要 类型 specifier 来解释存在栈中的参数.而之前的类型 specifier 仅对应了 int , double,及指针等类型.对于 C 中的其他类型并没有涉及. 就想 C 中 通过qualifier 来在基础类型上扩展一样,这里也通过 length modifier 来支持传入的“复合类...
Anyway, if the output was truncated due to this limit, the return value is the number of characters that could have been written. Notice that a value equal or larger than count indicates a truncation. Only when the returned value is non-negative and less than count, the string has been ...

To limit the formatted string to amax length substring, use theX.Ypattern whereXis the padding andYis the number of chars. In following example, we are first creating a substring of length 3 and then left padding it to 15 characters. Format to substring System.out.printf("'%15.3s' %n"...
类似于 sprintf）：printf -v pad '%0.1s' "-"{1..60}或类似的更动态的技术：printf -v pad '%*s' "$padlimit"如果您愿意，可以在一行上进行打印：printf '%s%*.*s%sn' "$string1" 0 $((padlength - ${#string1} - ${#string2} )) "$pad" "$string2"纯粹...
(length(args) >= 2 && (isa(args[2], AbstractString) || is_str_expr(args[2]))) || throw(ArgumentError("@printf: first or second argument must be a format string")) _printf("@printf", esc(args[1]), args[2], args[3:end]) end end """ @sprintf("%Fmt", args...) Return...
The String Flag %s This example formats strings using the "%10s" printf format. This format right-aligns the input strings by padding each string with spaces on the left until its length reaches 10 characters. Notice that if a string has multiple words, then the %s format only matches the...
An optional decimal digit string that specifies the minimum field width. If the converted value has fewer characters than the field width, the field is padded on the left to the length specified by the field width. If the-(left-justify) option is specified, the field...
If the output was truncated due to this limit then the return value is the number of characters (not including the trailing '\0') which would have been written to the final string if enough space had been available. Thus, a return value of size or more means that the output was ...
