Random access in File Handling Using C++ Programming Language

By Srivenurajulu G

This project is based on Random access in File Handling to enter users data in random and to search them. Here I have written code for finding the train number and details of it Using C++ program

Definition:

Random access means you can move to any part of a file and read or write data from it without having to read through the entire file.

ALGORITHM:

1. Start
2. Define class train
3. Read and print the train details using get() and print()
4. main()
5. Open file in write mode
6. If in==NULL. Print error in creating file otherwise goto 7
7. Call get()
8. Enter the data into the file
9. If the user wishes to continue repeat steps 7 and 8
10. Open the file in read mode
11. Enter the train no to be searched
12. Use seekg()
13. If found print train details
14. Close the file
15. Stop

Example:

We have to enter certain values here like train name, train no, starting place , ending place, date and time.
