integer to string

[petergrwl]

how do i write an integer value to a string , and specify the number of characters, and the data to be in hex?

so , if i have

x = 25;

i want to write it to a string, as
19

or if i have x = 5, i want to write to string as 05 (not just 5).


will itoa do this job?

itoa() is non-standard.

Alternatively, sprintf() is a possibility, but the C++ approach is preferable.
