Bank Management System Project with C++
Published January 09, 2022In this C++ Projects we are going to create C++ Bank Management System. This BMS is a console based application which can be used by Customers for Bank Related Transactions. It is a very simplified application and is very user friendly. We developed this project under Codeblocks editor. This Bank Management System project consist of below modules
- Create New Bank Account
- Deposit Amount to the Account
- Withdraw amount from your account
- Check Balance Inquiry
- Display All Account Holders List
- Update Bank Account
- Close Account
This C++ Bank Management System projects will be useful for academic engineers, student like CBSE board student who want to create their Mini Projects for respected academic year.
Let's create s C++ Project in Codeblocks IDE
Step 1: Launch Codeblocks IDE and Create New Project
It will launch below window, select Console Application and click Finish
Click Finish
Select C++ from the list
Now Enter Project name C++ Bank Management System and select destination path of the project and click Next
To run C++ code first we need to compile the code, to compile the c++ code we will select GNU compiler for this project and click finish
Now your c++ Bank Management System project will created
Step 2: Create a Account class to handle the Bank Account
This Account class contains properties like acno,name, deposit and type of account
and declare functions to add each module functionality
|
Step 3: Create Account
This Module will create an account. We will ask user to enter hie account No, Account Holder Name, Account type (Current/savings) and deposit amount.
void write_account()
{
account ac;
ofstream outFile;
outFile.open("account.dat",ios::binary|ios::app);
ac.create_account();
outFile.write(reinterpret_cast<char *> (&ac), sizeof(account));
outFile.close();
}
|
Step 4: Deposit and Withdraw Amount
void deposit_withdraw(int n, int option) { int amt; bool found=false; account ac; fstream File; File.open("account.dat", ios::binary|ios::in|ios::out); if(!File) { cout<<"File could not be open !! Press any Key..."; return; } while(!File.eof() && found==false) { File.read(reinterpret_cast<char *> (&ac), sizeof(account)); if(ac.retacno()==n) { ac.show_account(); if(option==1) { cout<<"\n\n\tTO DEPOSITE AMOUNT "; cout<<"\n\nEnter The amount to be deposited"; cin>>amt; ac.dep(amt); } if(option==2) { cout<<"\n\n\tTO WITHDRAW AMOUNT "; cout<<"\n\nEnter The amount to be withdraw"; cin>>amt; int bal=ac.retdeposit()-amt; if((bal<500 && ac.rettype()=='S') || (bal<1000 && ac.rettype()=='C')) cout<<"Insufficience balance"; else ac.draw(amt); } int pos=(-1)*static_cast<int>(sizeof(ac)); File.seekp(pos,ios::cur); File.write(reinterpret_cast<char *> (&ac), sizeof(account)); cout<<"\n\n\t Record Updated"; found=true; } } File.close(); if(found==false) cout<<"\n\n Record Not Found "; } |
Step 6: Check Balance Inquiry
void display_sp(int n) { account ac; bool flag=false; ifstream inFile; inFile.open("account.dat",ios::binary); if(!inFile) { cout<<"File could not be open !! Press any Key..."; return; } cout<<"\nBALANCE DETAILS\n"; while(inFile.read(reinterpret_cast<char *> (&ac), sizeof(account))) { if(ac.retacno()==n) { ac.show_account(); flag=true; } } inFile.close(); if(flag==false) cout<<"\n\nAccount number does not exist"; } |
Step 7: Display All Bank Account Holders list
void display_all() { account ac; ifstream inFile; inFile.open("account.dat",ios::binary); if(!inFile) { cout<<"File could not be open !! Press any Key..."; return; } cout<<"\n\n\t\tACCOUNT HOLDER LIST\n\n"; cout<<"====================================================\n"; cout<<"A/c no. NAME Type Balance\n"; cout<<"====================================================\n"; while(inFile.read(reinterpret_cast<char *> (&ac), sizeof(account))) { ac.report(); } inFile.close(); } |
Step 8: Modify Account
void modify_account(int n) { bool found=false; account ac; fstream File; File.open("account.dat",ios::binary|ios::in|ios::out); if(!File) { cout<<"File could not be open !! Press any Key..."; return; } while(!File.eof() && found==false) { File.read(reinterpret_cast<char *> (&ac), sizeof(account)); if(ac.retacno()==n) { ac.show_account(); cout<<"\n\nEnter The New Details of account"<<endl; ac.modify(); int pos=(-1)*static_cast<int>(sizeof(account)); File.seekp(pos,ios::cur); File.write(reinterpret_cast<char *> (&ac), sizeof(account)); cout<<"\n\n\t Record Updated"; found=true; } } File.close(); if(found==false) cout<<"\n\n Record Not Found "; } |
Step 9: Close an Account
void delete_account(int n) { account ac; ifstream inFile; ofstream outFile; inFile.open("account.dat",ios::binary); if(!inFile) { cout<<"File could not be open !! Press any Key..."; return; } outFile.open("Temp.dat",ios::binary); inFile.seekg(0,ios::beg); while(inFile.read(reinterpret_cast<char *> (&ac), sizeof(account))) { if(ac.retacno()!=n) { outFile.write(reinterpret_cast<char *> (&ac), sizeof(account)); } } inFile.close(); outFile.close(); remove("account.dat"); rename("Temp.dat","account.dat"); cout<<"\n\n\tRecord Deleted .."; } |
Step 10: Now create a Menu in main.cpp file to execute all above functions
int main() { char ch; int num; intro(); do { system("cls"); cout<<"\n\n\n\tMAIN MENU"; cout<<"\n\n\t01. NEW ACCOUNT"; cout<<"\n\n\t02. DEPOSIT AMOUNT"; cout<<"\n\n\t03. WITHDRAW AMOUNT"; cout<<"\n\n\t04. BALANCE ENQUIRY"; cout<<"\n\n\t05. ALL ACCOUNT HOLDER LIST"; cout<<"\n\n\t06. CLOSE AN ACCOUNT"; cout<<"\n\n\t07. MODIFY AN ACCOUNT"; cout<<"\n\n\t08. EXIT"; cout<<"\n\n\tSelect Your Option (1-8) "; cin>>ch; system("cls"); switch(ch) { case '1': write_account(); break; case '2': cout<<"\n\n\tEnter The account No. : "; cin>>num; deposit_withdraw(num, 1); break; case '3': cout<<"\n\n\tEnter The account No. : "; cin>>num; deposit_withdraw(num, 2); break; case '4': cout<<"\n\n\tEnter The account No. : "; cin>>num; display_sp(num); break; case '5': display_all(); break; case '6': cout<<"\n\n\tEnter The account No. : "; cin>>num; delete_account(num); break; case '7': cout<<"\n\n\tEnter The account No. : "; cin>>num; modify_account(num); break; case '8': cout<<"\n\n\tThanks for using bank managemnt system"; break; default :cout<<"\a"; } cin.ignore(); cin.get(); }while(ch!='8'); return 0; } |
