student record c++ programming project for beginners

Leave a Comment
Project Introduction and scope
It is a simple c++ project for beginners to cover some basic topics. Which can help c++ beginners to build large projects and gives idea about how to make project in c++ programming. To keep the project simple only basic functionalities has added it is recommended for students first understand the project flow then add more functions like edit record (hint code also has given below) etc. Best practice for students is to first add validation in this project which will not allow user to enter wrong option and then add more functions.

It includes the concept of following topics

  • struct 
  • Filing 
  • Loops
  • Arrays
  • If else
  • Switch statement
  • String class functions
Project has for major functions in menu

  1. Insert record
  2. Show all record
  3. Search record
  4. Exit program
How it works
Each  functionality has a function call in switch statement on the user choice control transfers to a function. Every function opens a file name "database" and insert, show and search data from it. File will be created where c++ file is placed in secondary storage.

C++ project source code

#include<iostream.h>

#include<fstream.h>

struct student

 file.write((char*)&obj,sizeof(obj));
 file.close();

   cout<<"\n\nFile Updated";
   break;

 while(1)

 // clrscr();
  cout<<"Enter 1 to Enter Record\n";
  cout<<"Enter 2 to Show All Record\n";
  cout<<"Enter 3 to Search Record\n";
  cout<<"Enter 4 to Exit\n";
  cout<<"\n\nEnter Option: ";
  cin>>option;

  switch (option)
  {
   case 1:
    add();
    cout<<"\n\nRecord Entered\n";
    getch();
    break;
   case 2:
    show_all();
    break;
   case 3:
    search();
    break;
   case 4:
    exit(0);
  }
 }
 getch();
}


sample input output
student record c++ programming project for beginners


Source code has been tested on Microsoft Visual C++ compiler. If you are running on a different compiler like codeBlocks. Some changes may required like add using namespace std; , remover .h from iostream etc.

Reference edit functionality c++ source code for practice

void edit()
{     //  clrscr();

 char user[15];
 cout<<"Enter registration Number: ";
 cin>>user;

 file.open("database.txt",ios::in|ios::out);
 file.read((char*)&obj,sizeof(obj));

 while (file.eof()==0)
 {
  if (strcmp(obj.reg,user)==0)
  {
   cout<<"Name: "<<obj.name<<endl;
   cout<<"Registration Number: "<<obj.reg<<endl;
   cout<<"Course: "<<obj.course<<endl;
   cout<<"CGPA: "<<obj.cgpa<<endl<<endl;

   cout<<"\nEnter New course: ";
   cin>>obj.course;

   file.seekp(file.tellg()-sizeof(obj));
   file.write((char*)&obj,sizeof(obj));
   cout<<"\n\nFile Updated";
   break;
  }

  file.read((char*)&obj,sizeof(obj));
 }
 file.close();

 getch();
}
