Dynamic Array Processing in C

Overview

This project implements a C program that processes records from a file (dataloger.txt) containing data from a measurement module. The program performs various commands entered by the user through standard input, such as opening files, creating dynamic arrays, validating data, and generating outputs.

Commands

  • v: Opens the data file (dataloger.txt) and reads its content into dynamically allocated memory. If the file cannot be opened, it prints Neotvoreny subor.

  • o [module] [type]: Sorts and displays records based on the given measurement module and type. The data is ordered by time and date. The module can be one of A1, A2, or A11, and the type can be one of R1, R2, R3, U1, U2, or U3. If the module and type are not found, it prints Pre dany vstup neexistuje zaznam.

  • n: Creates dynamic arrays to store data entries. If the dynamic arrays have already been created, it prints Pole je uz vytvorene.

  • c: Validates the data for correctness. This includes checking the format and ranges of the values. If any incorrect data is found, it prints a list of errors.

  • s [module] [type]: Saves the sorted data for the specified module and type to a file named vystup_S.txt. The data is ordered by time and date. It prints Pre dany vstup je vytvoreny txt subor.

  • h [type]: Generates a histogram for the given type. The type can be one of R1, R2, R3, U1, U2, or U3. The histogram is displayed in the console.

  • r: Displays measurement times in a reduced time format (hours and minutes only) instead of the full timestamp.

  • z [ID]: Deletes records for the specified ID. The ID must be an existing record identifier. It prints the number of deleted records.

  • k: Deallocates all dynamically allocated memory, closes any open files, and exits the program. It ensures a clean termination of the program.
