Sounds like homework.

[nffarah]

hahaha no i wrote the program but im not in the mood to write comments

[TarikNeaj]

Well, then wait until you are in the mood, and then you write the comments, we are not here to do that for you, sorry.

[nffarah]

what is your nationality

[fg109]

Not going to comment your code, and not going to keep reading this thread either, but:

class Account
{
private:
char number[8];	//account number
char type;	//account type s r or l
char owner[30];	//name of the owner
double balance;	//amount of money in the account
double InterestRate;	//interest
//...
}

Account :: Account()
{
number[8]='\0';
type='S';
owner[30]='\0';	// set the default values for constructor
balance=0.0;
InterestRate=0.05;
}

Why would we write comments for you? You are best suited to do that and it should be easy. Unless you didn't write the program.
