“printf” command in Linux is used to display the given string, number or any other format specifier on the terminal window. It works the same way as “printf” works in programming languages like C. Syntax:

If, like me, you like your hex presented as 0x1234CDEF, then you have to use 0x%08X to achieve the desired result. You could use %#.8X and that should also insert the leading zeroes. Try variations on the following code: Recommend:c – How to printf a 64bit

This is more of a curious query than an important question, but why when printing hex as an 8 digit number with leading zeros, does this %#08X Not display the same result as 0x%08X? When I try to use the former, the 08 formatting flag is removed, and it doesn’t work with just 8.

This gives the minimum number of digits to appear for d, i, o, u, x, and X conversions, the number of digits to appear after the radix character for a, A, e, E, f, and F conversions, the maximum number of significant digits for g and G conversions, or the maximums S

So the general format of format specifier is: %[flags][width][.precision][length]specifier : Other additional arguments specifying the data to be printed. They occur in a sequence according to the format specifier. printf() Return value If successful, the printf() function returns number of characters written. On failure it returns a negative value.

The simplest output statement is the by-now familiar “print” statement. There’s not too much to it: “Print” by itself prints the input line. “Print” with one argument prints the argument. “Print” with multiple arguments prints all the arguments, separated by spaces (or
