need help with 10% penalty for program

#include <iostream.h>

int Acct = 0;
double BegBal;
double totchar;
double totcred;
double credlim;
double newcredit;



int main(void)

{
//cout<<"ddd";
while (Acct != 1)
{
cout<<"Enter account number (-1 to end) $$$$$ : ";
cin>>Acct;

if (Acct != -1)
{
cout<<"Enter beginning balance u dick: ";
cin>>BegBal;

cout<<"Enter total charges u $$$$$$$: ";
cin>>totchar;

cout<<"Enter total credits u pussy: ";
cin>>totcred;

cout<<"enter credit limit: ";
cin>>credlim;

newcredit = ((BegBal + totchar) - (totcred));

if (newcredit > credlim)
{
cout<<"account: "<<Acct<<endl;
cout<<"credit limit: "<<credlim<<endl;
cout<<"balance: "<<newcredit<<endl;
cout<<"credit limit exceeded u dumbass."<<endl;
}
}
}
return 0;
}


we need to add a 30$ fee when the credit limit is exceeded and a 10% of the remaining balance that is left over

Then you might consider to start putting this two things in. If you have problems coding those conditions, ask a question.

Post using code tags in future, please.
