This is the text file:
.- ...- ..--- .-- .... .. . -.-. -..-  ....- .....
-... .... ...--


The text file outputs:
1
2
 
AV2WHIECX45
BH3


If there are two spaces instead of one space then that means new word, which is after the X, so it supposed to output:
1
2
 
AV2WHIECX 45
BH3

I think your input file is missing some key information :P [EDIT] the OP was modified and the full input is there now [/EDIT]

Anyways, you are going to want to read in the spaces and then if there are 2 in a row output a space.

You could do that by doing something like if(ss.peek() == ' ') {cout << ' ';}

Though I personally would be using if / else and not if / if / if...

PS put the peek statement after line 47 but before line 48.


Here is a slightly modified version of your code (I used cpp.sh so I changed it from input file to string/stream)
