Answer 1

Basically you want to merge 3 strings, so prepare a result buffer (char array) big enough to contain the 3 strings, the spaces in between, and one null character for string terminator.

Then you can use strncat() function from <string.h> to copy the 3 strings content into the result buffer. You can make use of a loop in case there are many strings to be merged e.g. when the strings to be merged are array elements.
