Format specifiers are meant to make the string more dynamic. What you have is an error. The point of using format specifiers (%f, %d, etc.) is so that you may update the value in the string, if it's ever to change.

1. 14.5 should be replaced with %f
2. You didn't pass your variable to printf as an argument, so no value is being supplied where %f is

float price = 20.99;
printf("My meal came out to be %f dollars.", price);

Let's say the cashier decides to give me a 20% discount.

float price = 20.99
float discount = .20 * price;
price -= discount;
printf("My meal came out to be %f dollars.", price);

My value updates without the need to statically type the new price in.

Also, this is an Obj-C question, not General Discussion.

It helped thanks!

include <stdio.h>

int main () { float radius = 14.5; printf("A ball with a radius of %f inches.", radius);

return 0; }

I don't know what's wrong with this answer, it just not right..
