I just started taking C classes this past semester and I am having trouble with one of the homework problems I was assigned. Of course I have made an attempt at it but to no avail.

I am currently using Visual Studio 2008 Beta and when do "Build Solution" no errors come up at all. When I run the program, the first line prints as it should but as soon as I enter anything, it crashes.

The point of the homework was to design a program where a person can enter the account number, current balance, the amount charged, credits available, maximum credits, and it should print the final balance after all that and tell you if the consumer had exceeded the credit limit or not.

Below is what i have so far and any help is greatly appreciated.

int main()
{
int account;
float balance;
float charge;
int credits;
float creditLimit;
float balanceAll;

account = 1;
balance = 0;
charge = 0;
credits = 0;
creditLimit = 0;
balanceAll = 0;

printf(" Enter account number (-1 to end): ");
scanf_s("%d", account);
printf("\n Enter beginning balance: ");
scanf_s("%f", balance);
printf("\n Enter total charges: ");
scanf_s("%f", charge);
printf("\n Enter total credits: ");
scanf_s("%d", credits);
printf("\n Enter credit limit: ");
scanf_s("%f", creditLimit);

while ( account >= 1 )
{
if ( creditLimit < balanceAll )
{
printf(" Account Number: \n", account);
printf(" Credit Limit: \n", credits);
balanceAll = balance + charge - credits;
printf(" Balance: \n", balanceAll);
}
else
{
printf(" Account Number: \n", account);
printf(" Credit Limit: \n", credits);
printf(" Balance: \n", balanceAll);
printf(" Credit Limit Exceeded \n");
}
}
return 0;
}
