it will only read the first C and D and not the rest *

i added ins.get(next_char) to try and make the end of file work but it did

This will explain to you how to use code tags

Not the source of your problem but you should change void main () to int main().

The problem your having is because you close the file after you read it once.
move ins.close(); outside your while loop

//getch();
ins.close();
return 0;
}

its still running in a infinite loop. what is return 0; im getting a syntax error when i put that because it says 0 is not defined

[makaveli23]

i got return 0 to work and now its not running in a infinite loop but the program is only reading my first value , i'm assuming it has something to do with my if statement but im not sure how i would be change it

[makaveli23]

this is what im outputting:

Your beginning balance is $879.46

You have cashed a cheque for $ 400
You are charged a service charge of $0.15 is applied when cashing a cheque
Your new account balance is $ 479.31

Your current account balance has dropped below $500.00
A service charge of $5.00 will be applied
Your current balance is $ 474.31
You have made a deposit of $ 400
You will be charged a service fee of $0.10
Your current balance is $ 874.21
