Code help.

So I have thing called "labs" in my comp. sci class. Here is my current lab (learning C code, no C++):

It says to determine whether a customer has exceeded the store credit. My theory would be to use an if statement but the problem is we haven't learned what an if statement is yet, and the labs should be done with the knowledge I have been taught with. So is there another way to determine whether or not a customer has exceeded store credit?

 

Oh yeah, also how does a store credit system work?

There's no intelligent way to do it without an if....so I'm sure you can use an if statement. 

 

Its simple: 

if(statement == true){

    do this;

} else { 

     do this; 

}

 

A store credit -- you have x amount that you're allowed to spend until you pay it off.

So in my example, how would you calculate new account balance and credit remaining?

account balance = previous month's balance + this months charges. Then check if that number exceeds the maximum credit limit 

 

Credit remaining would just be max credit - account balance.

But would payments affect the account balance (assuming payments mean that the customer is paying off the credits)? So wouldn't it be 
account balance = start balance + charge - payments?

Whoops, missed that, and yes they would.

Ok thank you so much
