What I might do is put a marker in between each question in the file so that one can be read at a time , like:

A for loop is designed to

a.)run only if the condition is false
b.)run a set number of times
c.)run at least once
d.)run when there are no conditions

@

A while loop is designed to

a.)run only if the condition is true
b.) run a set number of times
c.)run at least once
d.)run when there are no conditions

so that you can read up to the ‘@’ character , stop and get the answer and then continue. You could make the while loop read one word at a time ( stopping when you read ‘@’ ) and then get the answer.

yeah but how to put it into coding??

This version works with this file format:

A for loop is designed to

a.)run only if the condition is false
b.)run a set number of times
c.)run at least once
d.)run when there are no conditions
