Answer:
The QBasic program is as follows:
10 INPUT "First name: " fName$
20 INPUT "Middle name: " mName$
30 INPUT "Last name: " lName$
40 PRINT lName$," ",mName$," ",fName$
50 END
Explanation:
This prompts the user and gets input for first name
10 INPUT "First name: " fName$
This prompts the user and gets input for middle name
20 INPUT "Middle name: " mName$
This prompts the user and gets input for last name
30 INPUT "Last name: " lName$
This prints the output in the required format
40 PRINT lName$," ",mName$," ",fName$
This ends the program
50 END
