Concatenate a character at the end of an lpstr string

[ssimop]

I need to concatenate a character at the end of each one of the elements of an lpstr string. In the first place it works. However, when I try to access the elements of the string I always get, to every element, the value of the last element. I attach the code I use. Any advice regarding my error will be much appreciated. Many thanks in advance.

Function tempf07

Code:
