You 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.
Yes, you can specify variable width, however you can't specify precision. The format tags are as follows:
scanf: %[*][width][length]type
printf: %[*][width][.precision][length]type
As you can see, scanf lacks the precision tag but does include the length tag.

we have to construct a table of two field structures,where the first field is the funtion name as a string and the second field is just the function name.then search the table to get a string match in the first field and use the second field to call the function.
You must have declared a method which tries to convert a variable/field value into a numeric value but that is not possible. Refer to the line on which the error is found and remove the method which tries to convert the variable/field. Note: Java allows type casting so a string cannot be converted into integer even if a method tries to change the value
For example, there are few string values of "1-5", ">5", "0-0.9", and "<0" from one field in attribute table. Then I need to sort both "1-5" and ">5" to a new field. How do I make the field calculator for this? Thank you!
A field is an attribute. A field may be a class's variable, an object's variable, an object's method's variable, or a parameter of a function. class bike{ static int bikes;int gear;int cadence; void create( int newGear, int newCadence ){bikes = bikes + 1;gear = newGear; cadence = newCadence;} int getSpeed(){int speed = gear*cadence*5*3.141;return speed;}} 'bikes' is a class's variable (class variable) (static field). 'gear' and 'cadence' could be an object's variables (instance variables) (non-static fields). 'speed' is an object's method's variable (local variable). 'newGear' and 'newCadence' are parameters of a function (parameters). Refer to related links section
In simple terms, if flux density increases, then field strength increases and vice versa. The flux density is equivalent to field strength times with a variable.

The amount of data stored in such fields can vary in length. Usually you do specify a maxmimum length so that databases can optimize how data is stored and accessed.

What characteristics could a database field have, such as data type, field name, field size and field format?
PHP provides a function called empty($var), which tests if $var is "empty." Empty has an odd definition, since the function returns true if the variable loosely equates to False. Although a zero-length string would be considered empty, so would the string "0" (among other irrelevant values).To accept the value "0" from a field, use strlen($var). It tests the length of any variable, after casting it to a string. If this function truly equals integer zero (compared with triple-equals), the variable must be empty.
You didn't specify which numbers. The field numbers are 2,3,4,9,10,11,12. The numbers that are not in the field are 5,6,7,8

That refers to a variable attached to an object - also known as a field.
String
Fields specify how a field can work, what kinds of data can be put in to a field size and other things. You need to specify formats for numbers and dates. You need to specify the size of text fields. There are many optional properties which can prove useful in different situations. Doing validation on a field can be useful to reduce errors. You can ensure data is entered into a field. There are so many other things that properties do. So they are an essential part of designing a field in a database.
