combining numbers & characters to display on TM1637

I want a display to show

number + number or blank + number or blank + number

I’ve tried <SevenSegmentExtended.h> and <TM1637Display.h> but can’t get what want. The first of these would seem easiest, if I could simply build up a text string (= 1 + ’ ’ + ’ ’ + 2) then display it, but I can’t work out how to do this ;(

Or is there an easier way?

snprintf() can build a text string from numbers, strings and characters. So can sprintf(), but snprintf() makes it harder to shoot yourself in the foot.

thanks, will look into this.
