Personal Diary Management System using C++ (With Source Code)
Personal Diary Management System using C++ (With Source Code)
Hello, coders. Welcome to the codewithrandom blog. In this article, we will learn how to create a Personal Diary Management using C++ (With Source Code).
A Personal Diary Management System implemented in C++ programming language is a simple software for a personal diary entries. It is built on the idea of saving and generating all of the user’s stories. After passing through the login system, the user may add, read, edit, and delete stories. In order to see, amend, or delete the story, the user must first supply the password. The entire project was created in the ‘C++’ programming language, and several variables and strings were employed in its creation. The users will find this project simple to use and comprehend.
Patient Management System using C++ (With Source Code)
This project is user-friendly and may be tailored to your specific requirements. The system has a straightforward capability for storing your personal diary recordings. The project has a basic code script that is easy to learn and understand.

Features Of the System:
- The system contains a Login System which lets the user access it only after the correct password has been entered.
- The system provides an option to edit the pre-defined password.
- A user in the personal diary can Add a story,
- View a story or stories
- Edit a story
- Remove a Story
Overview of the UI:
- Main Menu of the Personal Diary:
***********************************
DAILY DIARY MANAGEMENT SYSTEM
***********************************
MAIN MENU:
ADD STORY
VIEW STORY
EDIT STORY
DELETE STORY
EDIT PASSWORD
EXIT
ENTER YOUR CHOICE:
- if wrong choice is entered:
YOU ENTERED WRONG CHOICE..
PRESS ANY KEY TO TRY AGAIN
The user will choose an option to perform the operation of their choice. User will then enter a values according to the prompts that will be displayed on the console to perform that operation.
Personal Dairy Management System code:
You can directly use this code by copying it in your IDE to understand the working and then can create it by understanding the project.

pass – pass
Now let us understand the code:-
- We will start by writing the header of the code with the required libraries – stdio.h (standard input/output), stdlib.h (memory management),iostream (input and output stream), conio.h (console input/output), string.h (string manipulation).
- Now we will give forward declarations for the functions which will be used in this project –int password();void addrecord();void viewrecord();void editrecord();void editpassword();void deleterecord();
- We will create a structure called ‘record’ using the keyword ‘struct’ which will contain information related to the records of the diary. The arrays in the structure are –time[6];char name[30];char place[25];char duration[10];char note[500];
- The login() function will contain the functionality required to create a login system using password. The user will enter a predefined password to get the access. We will initialize a string type variable called pass which will be used to check for the password entered by the user with the predefined password. The password in this system is ‘pass’. You can change it in the source code according to your choice as well. This function will also display the heading on the console – ‘Personal Diary Management’. We will use an if-else control statement to display access granted else aborted if the password entered is something else.
- The main() function will first display the menu of options to perform in this system – add story, view, edit, delete, edit, exit. The user will enter the choice. We will use a switch case to select among the options to perform.
- The addrecord() function will let the user add the record of personal diary into the system – providing details like date, time, name, place, duration, and note. It will prompt the user to enter date of record. Instead of filename, write the name of the file text file where you want your records to get stored.
- The viewrecord() function will allow the user to examine previous diary entries. The user has the option of seeing the complete diary for a certain day or viewing a single entry based on the time. We will use a switch case fore the functionality.
- The editrecord() function will let the user edit the already existing records. The user needs to provide the current password and then enter a new password. The user can edit the choice of entry they want.
- The password() function will let the user enter the password to get access to the system. We will be declaring and initializing 2 char type arrays – pass[] – to store the entered password and check[] – to store the predefined password stored in a file. To enter the password, only 3 trials are given. The user will enter the password and it will get assigned to pass[]. It then uses fpp=fopen(“SE”,”r”) to open a file named “SE” in read mode. The password is believed to be saved in this file. If the file does not exist, an error message is displayed and a 1 is returned to indicate an error. We will be using strcmp(pass, check), the inputted password is compared to the decrypted password stored in the check array. If the passwords match, it shows an access permitted message and returns 0 to indicate that authentication was successful.
- The edit() password function allows the user to edit the password. The user needs to provide the current password and then enter a new password.
- The deleterecord() function allows the user to delete the password. The user has the option of deleting the whole diary for a certain day or deleting a single entry based on the time. We will be using switch case in this function inside the loops. The fflush() predefined function is used to flush the output buffer of the stream.
- This sums up our project of Creating Personal Diary Management System using C++.
