Struct not declared problem

XiangzhenWu (10)
The program debugger says that 'student' was no declared in this scope.
The coding program i use is CodeBlocks.

Where did you declare student?

Finger trouble :-)

in line 39 you used a comma "," instead of a full stop "."

Change:DisplayStudentData(school,student[i]);
To:DisplayStudentData(school.student[i]);

In case full stops are a valuable resource in your neigbourhood, I've included several - feel free to request more if you run out anytime.

"................................................................................................................................................"

It's been a long day, I usually make better jokes than this :-(
