Yes, IF we knew what you needed hwlp with.
1) Use CODE tags around all the code
2) A complete explanation of what you are trying to do and what actually happened is necessary.

We were trying to get info about a student from a .dat file we created before. But when i try to compile my
codes it stopped working.

What does that mean? How can your code stop working when you compile it?

Member Avatar for zeroliken

judging from the code you posted most of the variables have no value yet your trying to print them?
