Thread: keep getting error C2064: term does not evaluate to a function taking 1 arguments

Can someone tell me what this means? I keep getting this error on a couple lines. (Will bold to let you know which ones) I would really appreciate it. Thanks!

Well it's pretty clear, innit? NohalfDollars is so not a function, but just a variable. C doesn't do implicit multiplication, like 5x doesn't mean 5 * x; you need to put the * in there yourself.

ok i get that. i fixed it by multiplying it using the *. But when i run it, it prompts me for pennies(the first prompt) but then it doesn't prompt me for the quarters, dimes, etc and automatically sums it up. Do you know why it wouldn't be prompting me for the others?

If you type a letter, or even a decimal point, then that's the end of input -- %d won't read anything for a letter or a decimal point.

ohh i see. thanks a lot for the help. I was typing it with a decimal. Makes perfect sense now. Thanks so much!! I really appreciate it!
