Fix for my code

noir234 (10)
Hi, if my input is 3 3 3 *
output will be 3***3***3***3

However there should be an exception where if the user inputs n, the letter n would then be represented by numbers like such:
input:

3 3 n b

output:

0bbb1bbb2bbb3

the problem in my code is that instead of 0bbb1bbb2bbb3, the 3 is instead becomes the letter n (0bbb1bbb2bbbn) which is not the one im looking for.

@The Grey Wolf may i ask what does the fill do?
The Grey Wolf (170)
fill is a std::string, sequence of chars, in the example it is created and initialised with '~~~'. The reason I used it was to take the embedded for loop out of your code as it doesn't change each time around the outer loop.
