C++ banking program.....I have not learned "Class" yet. How can I change this code to a simple banking screen.

#include #include #include #include using namespace std; class account { int accountnumber; char name[50]; int deposit; char type; public: void create_account(); void show_account(); void modify_account(); void deposit_funds(int); void draw_funds(int); void get_report(); int get_accountnumber(); int get_funds(); char get_accounttype(); }; void account::create_account() { cout<<" Enter The account Number: "; cin>>accountnumber; cout<<" Enter The Name of The account Holder : "; cin.ignore(); cin.getline(name,50); cout<<" Enter account type (enter s - saving or c - credit): "; cin>>type; type=toupper(type); cout<<" Enter The Initial amount(500 or more for Saving and 1000 or more for current ): "; cin>>deposit; cout<<" Account Created Successfully..."; } void account::show_account() { cout<<" Account Number: "<>type; type=toupper(type); cout<<" Modify Balance amount: "; cin>>deposit; } void account::deposit_funds(int x) { deposit+=x; } void account::draw_funds(int x) { deposit-=x; } void account::get_report() { cout<>opt; system("cls"); switch(opt) { case '1': system("color 02"); write_account(); break; case '2': system("color 03"); cout<<" \tEnter The account No. : "; cin>>num; deposit_withdraw(num, 1); break; case '3': system("color 06"); cout<<" \tEnter The account No. : "; cin>>num; deposit_withdraw(num, 2); break; case '4': system("color 08"); cout<<" \tEnter The account No. : "; cin>>num; display_sp(num); break; case '5': system("color 9"); display_all(); break; case '6': system("color 10"); cout<<" \tEnter The account No. : "; cin>>num; delete_account(num); break; case '7': system("color 11"); cout<<" \tEnter The account No. : "; cin>>num; modify_account(num); break; case '8': system("color 04"); cout<<" \tThanks for using Bank Managemnt System"; break; default :cout<<"Invalid Option "; } cin.ignore(); cin.get(); if(opt=='8') break; } return 0; } void write_account() { account ac; ofstream outFile; outFile.open("account.dat",ios::binary|ios::app); ac.create_account(); outFile.write(reinterpret_cast (&ac), sizeof(account)); outFile.close(); } 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 !!
