Hi i need some help for my program which is banking system

I have two problems which is the objective of the program, but i cannot do

First Problem : The objective of the program is to create first or open an account before activating the other options. i cannot do it

Second Problem: If the user will deposit the money, automatically there is a 500 minimum or initial deposit, and if he will withdraw, the 500 will remain, there is should be a 500 still there,

Here is the code guys:

#include <stdio.h>
#include <dos.h>
#include <stdlib.h>
#include<iostream.h>
#include<conio.h>


//void heading(void);



void main (void)
{
char name[32];
float bal,x;
int c1,c2, mdeposit=500;
c2=bal=0;
c1=1;
while (c1 != 0)
{
clrscr();

//heading();
cout<<"========================================\n";
cout<<"=Welcome to Gomez Bank=\n";
cout<<"========================================\n";
cout<<"1. Open Bank Account\n";
cout<<"2. Check Balance\n";
cout<<"3. Deposit\n";
cout<<"4. Withdraw\n";
cout<<"5. Close Bank Account\n";
cout<<"6. Exit\n";
cout<<"Please enter your transaction: ";

cin>>c1;
clrscr();


switch(c1)
{
case 1:

cout<<"\nPlease Enter Your Full Name: ";
gets(name);
do
{
clrscr();
cout<<"\n\n\t\t\tNote 500 is the minimuim deposit";
cout<<"\n\nPlease Enter Your Initial Deposit: ";
cin>>x;
bal = bal + x;
getch();
}while(bal < 500);
mdeposit = 500;
cout<<"Would you like to do another transaction?\n";
cout<<"1.Confirm 2.Exit\n";
cout<<"Enter your choice: ";
cin>>c2;
if (c2 == 2)
{c1 = 0;}
else if(c2 ==1){

break;
}

case 2:
cout<<"Your current balance is: "<<bal<<"\n";
cout<<"Would you like to do another transaction?\n";
cout<<"1.Confirm 2.Exit\n";
cout<<"Enter your choice: ";
cin>>c2;
if (c2 == 2)
{c1 = 0;}
else;
break;


case 3:
cout<<"Enter the value you would like to deposit: ";
cin>>x;
while(x<=0)
{
cout<<"The value you've entered is invalid. \nPlease try again: ";
cin>>x;
}
bal = bal + x;
cout<<"Would you like to do another transaction?\n";
cout<<"1.Confirm 2.Exit\n";
cout<<"Enter your choice: ";
cin>>c2;
if (c2 == 2)
{c1 = 0;}
else;
break;


case 4:
cout<<"Enter the value you would like to withdraw ";
cin>>x;
while (x > bal || x <=0)
{
cout<<"The value you've entered is invalid. \nPlease try again: ";
cin>>x;
cout<<"Would you like to do another transaction?\n";
cout<<"1.Confirm 2.Exit\n";
cout<<"Enter your choice: ";
cin>>c2;
if (c2 == 2)
{c1 = 0;}
else;
}
bal = bal - x;
break;


case 5:


case 6:
c1 = 0;
break;
}
};

cout<<"\n\n\n\t\tThank you for using Gomez Banking Systems!";
getch();

}





Thanks in advance

Hi david123456!
There're some tips for you:
Can you give us your example output that you should have?
Put your code into code format tags - the <> button on the right. This makes your code easier to read and more people will ready to help you.

Hope all goes well...
david123456 (24)
Hi,

Thanks a lot for replying my message, uhm i really don't know how to format tags, since i am newbie in programming, hehe

The output should be the menu first, with 6 choices

1.open bank account
2. check balance
3.deposit
4.withdraw
5.close bank account
6.exit

the objective is to display this 6 items but first they need to choose number 1 which is the open bank account, if they choose other number, it will come up with error and it will just comeback to the menu that is my first problem, cant do it, second problem after creating a bank account, all the options will be enabled but they cannot create a bank account again, they should close it first, third problem if they deposit, there will be 500 minimuim deposit, and if they withdraw they cannot withdraw exceeding to that 500, i will post more organized code, i had here a algorithm for the initial deposit, but its not working


Please i need some help, thanks a lot

Just click 'Edit' to enter edit mode, you'll see a format menu on the right. Click <>, then put your code into the tabs you've just received (Eg : <code> Code </code>) And your code is ready !!!!


And anything else? Only menu items? Final output results?
Tell us the your example expected output from your mind.

Your program demonstration algorithm:

the objective is to display this 6 items but first they need to choose number 1 which is the open bank account, if they choose other number, it will come up with error and it will just comeback to the menu that is my first problem, cant do it, second problem after creating a bank account, all the options will be enabled but they cannot create a bank account again, they should close it first, third problem if they deposit, there will be 500 minimuim deposit, and if they withdraw they cannot withdraw exceeding to that 500, i will post more organized code, i had here a algorithm for the initial deposit, but its not working


Gomez Banking Systems
////////////////////////////////////////////////////////
Step 0 : Inits (openBank = false)
////////////////////////////////////////////////////////
Step 1 : Displays 6 items, inputs (number)
////////////////////////////////////////////////////////
Step 2 : (number == 1) //Opening the bank account

Case 0 : (openBank == false) Opens the bank account, Inputs name, openBank = true goto Step 1
Case 1 : (openBank == true) Displays an error Msg, goto Step 1
////////////////////////////////////////////////////////
Step 3 : Check (number)
If (number != 1) and (openBank == false) Displays an error Msg, goto Step 1

Else Commands.... (Not given)

Does this help?

You've already posted the errors of this source? Okay, I've fixed it.
You, Turbo C++? (I'm VS, different) ? :)

Yes, i am using turbo c++, thanks again, i will wait for your reply thanks so much

The errors are

3. Undefined symbol 'false'
4. Undefined symbol 'true'

Thanks a lot for your help all the way, appreciate it
Imadatobanisa (647)
Have you reviewed and recopied the fixed source and applied it yet? I haven't seen any change from your posted source.
Maybe the global function feature is not supported.
Edit : Any another error?
Sorry, and I'll need to download and test Turbo C ++

And I'll review your code again and give you advices :)

Hello , good day, yes i applied everything, thank you so much, i already solved the initial deposit, the only problem that i had, is this 4 errors, the open account and the close account, That's the only problem that i had please help me,. thanks again in advanced, if you want i can send to you the software if you will give me your email address,

Back to your code :

Remark your new & changed code (honest) :
1- No comments (Eg : variable names too short (r,e,b, etc...), no correct meaning)
2-
cout << "\n\n\tPlease create an account first.";

Don't use too many because it's not necessary. Eg Before check a input choice :
if(choice != OPEN && openBank == false) //If your choice is not "Open bank command" but the bank hasn't opened yet

3-
double oa(double);
double dt(double);
double wt(double);
double bi(double,double,double);
double ca(double);

?!?!?!?!??!?!?!?!?!?!?!?!?!?!?!?!??!?!?!?!?!?!?!?!?!??!?!?!?!?!?!?!?!?!?!?!??!?!
Nobody knows, except you. (Add comments & parameter names)
4-
bool q; cin >> q;

"cin" command doesn't support input boolean values. Use 'int' instead.


?!?!!?!??!?!?!?!?!?!?!?!?!?!?!
-> Keep the old one is better.
(Take the code above as an example)
