In the Series of C Beginner Project we will create a simple Bank Management System with C Language. When you hear the name of this c project, the idea of the project suddenly strikes you. It is to perform bank operations like starting a bank account and managing transactions (including credit and debit). There are inbuilt operations in this project that helps you to remove an account and also to check the list of existing customers. This project works like a real bank performing bank realistic activities. It is a console-based application that is built using GCC compiler, and you can download the source code for this program from the download button after the image. The password for this bank management system project is "banklogin"
This C Bank Management System projects consist of below modules:
Login Module:
int main() { char pass[20],password[20]="banklogin"; int i=0; printf("\n\n\t\tEnter the password to login:"); scanf("%s",pass); if (strcmp(pass,password)==0) {printf("\n\nPassword Match!\nLOADING"); for(i=0;i<=6;i++) { fordelay(100000000); printf("."); } system("cls"); menu(); } else { printf("\n\nWrong password!!\a\a\a"); login_try: printf("\nEnter 1 to try again and 0 to exit:"); scanf("%d",&main_exit); if (main_exit==1) { system("cls"); main(); } else if (main_exit==0) { system("cls"); close();} else {printf("\nInvalid!"); fordelay(1000000000); system("cls"); goto login_try;} } return 0; } |

Menu Screen
After Login We will navigate to Menu Screen
The Menu screen code will be like below
void menu(void) { int choice; system("cls"); system("color 8"); printf("\n\n\t\t\tCUSTOMER ACCOUNT BANKING MANAGEMENT SYSTEM"); printf("\n\n\n\t\t\t\xB2\xB2\xB2\xB2\xB2\xB2\xB2 WELCOME TO THE MAIN MENU \xB2\xB2\xB2\xB2\xB2\xB2\xB2"); printf("\n\n\t\t1.Create new account\n\t\t2.Update information of existing account\n\t\t3.For transactions\n\t\t4.Check the details of existing account\n\t\t5.Removing existing account\n\t\t6.View customer's list\n\t\t7.Exit\n\n\n\n\n\t\t Enter your choice:"); scanf("%d",&choice); system("cls"); switch(choice) { case 1:new_acc(); break; case 2:edit(); break; case 3:transact(); break; case 4:see(); break; case 5:erase(); break; case 6:view_list(); break; case 7:close(); break; } } |
