Re: Pascal : Access a file of 100 Quiz questions so 12 Random ones are displayed?

from i what i saw in your code you read from the file with questions and print the question on screen. now, why you don't read the entire file, built that array of records, apply the randomize and then put a question from that array?
e.g: ado is that array of records.
randomize;
cycle
put_question: ado[random(i)+a_value]
end_of_cycle
i hope you understand the principle.
best regards,
e.g: ado is that array of records.
randomize;
cycle
put_question: ado[random(i)+a_value]
end_of_cycle

best regards,

Yes I fully understand now, thanks for your help mate!
I'll go away and try this.
edit
Im pretty sure Cycle is a mac extension but Continue does exactly the same and the main reason was to understand your point for which Im grateful.

ok, i'm sorry for my mistake, i only tried to explain it in a pseudocode manner.
so,
e.g: ado is that array of records.
randomize;
cycle//this can be a while, repeat,ect. you must think until when this cycle is going.
put_question: ado[random(i)+a_value]
end_of_cycle
hope that now is more obvious

Sure but its not going to be done for a while cos I have a big exam to study for and as I stated at the start my program already meets the project requirements so I'll just hand it in without the random function.
Although I plan to do the random feature after my exam (end of May) and when it is done I will happily post it up here.
