echo 2 txt files to screen no carraige return

Shell Programming and Scripting

I have two text files, each of then only containing ONE line and NO carraige return or white space at the end...how do I echo both of these text files to the screen without putting an extra line? I want to do this from the command line.

file1.txt:
this is file1.txt 1

file2.txt:
this is file2.txt 2

I want the output to screen to look something like this:
#
this is file1.txt 1 this is file2.txt 2
#

if I cat the files it looks something like this:
# cat file1.txt file2.txt
this is file1.txt 1
this is file2.txt 2
#

but again, I want the output to be on ONE line.....

What about paste?

paste file1.txt file2.txt

As danmero said 'paste' is a good and direct option.

 paste file1.txt file2.txt

Also you can set the delimter if you don't want to go with tab

 paste -d ":" file1.txt file2.txt

Also, you can get the normal mode also (using carriage return)

 paste -s file1.txt file2.txt
