Iterate through a file and parse in a bash script

I have a file that is filled with Full Names and Username, the file will look like this 

Bob Smith bsmith
David Miller dmiller
...

I could do this one at a time by doing:

useradd -c "Bob Smith" -d /home/bsmith -s /bin/bash bsmith

But I want to figure out how to iterate through my file with a while loop and use variables maybe to do this. Thanks!

You can use something like this

$ while read a b c; do echo -e "first: $a \t second: $b \t third: $c"; done << EOF
> Bob Smith bsmith
> David Miller dmiller
> EOF
first: Bob       second: Smith   third: bsmith
first: David     second: Miller          third: dmiller
