account::account(int i)
{
if (i<0)

balance=0;
cout<<"Error=>>Value of balance is negative";
}
else
{
i=balance;
}
}
void account::credit(int j)

}
void account::debit(int k)
{
if (k>balance)
{
cout<<"Error :Taking Money is more from Total Money";
}
else
{
balance -= k;
}
}
int account::getbalance()
{
return balance;
}
void account::printbalance()
{
cout<<balance;
}
int main()
{
	int i,j,k;
cin >> i>>j>>k;
account ac(i) ;
ac.credit(j);

What do you mean by 'it doesn't work'?

when I enter 3 numbers (value of balance,taking money, adding money) ,program shows negative digits with this message:
Error :Taking Money is more from Total Money

In the constructor

account::account(int i)
{
if (i<0)
{
balance=0;
cout<<"Error=>>Value of balance is negative";
}
else
{
i=balance;
}
}


you shall change statement

i=balance;

to

balance = i;
