Can you specify variable field width in scanf format string?
AnswerYou can't specify a variable field with a fixed format string, but you can get around this by making the format string variable:int width; char format[20]; /* or whatever size is appropriate */ int value; ... sprintf(format, "%%%dd", width); /* generates a string like "%5d" */ scanf(format, &value); The only drawback to this method, other than requiring two statements, is that the compiler can't do a sanity check on the arguments to scanf like it can when the format is a string constant.AnswerIf you want to specify a variable width in a printf format string (as opposed to scanf), you can do the following:printf("%*d", width, num);That will use the value of "width" as the width for formatting the value of "num" as a decimal integer.
