Following is the printf statement to print 1.234 in a 9-digit field with preceding zeros:

printf ( “%09.3f\n”, 1.234 ) ;

The printf statement prints the given floating-point number in the field of 9 digits and preceded by zeros. Thus achieved by placing 09 immediate to the right of % sign.

Digit 3 after the decimal point is used to provide precision up to 3 values.

Given information:

Print unsigned integer 40000 left justified in a 15-digit field with 8 digits.

Explanation:

Following is the print statement to print an unsigned integer 40000 left justified in a 15-digit field with 8 digits:

printf ( “%-15.8u”,40000 ) ;

The printf displays the given number as 8 digits with left justification in a l5 digit field.

-15 placed to the immediate right of % sign, is used to left justify the number and occupy 15 spaces.
Digit 8 after the decimal point places zeros to the left of the number to make it an 8-digit number.
Conversion specifier u is used to print unsigned numbers.
