Specifying maximum printf field width for numbers (truncating if necessary)?

Question

You can truncate strings with a printf field-width specifier:

printf(\"%.5s\", \"abcdefgh\");

> abcde

Unfortunately it does no

Answer 1

You could use snprintf to truncate from the right

char buf[10];
static const int WIDTH_INCL_NULL = 3;

snprintf(buf, WIDTH_INCL_NULL, "%d", 1234); // buf will contain 12
