Objective C Syntax Error

Question

printf("%f A ball with a radius of 14.5 inches.");

How do I correct this? I am trying to write a print function(Still pretty green when it comes to C) I am not sure how to correct it.

Answer 1

You may or may not be receiving a compilation warning with this because you are calling printf, have a specifier in your format, but do not provide a value. "%f" expects for you to pass a float value to it. The following:

printf("A ball with radius of %f inches.", 14.5f); 

should work, if that is what you are looking to do. If it is, you might need to augment the %f to adjust for precision (something like "%.1f" ).

Otherwise if you actually want to print the %f outright try this:

printf("%%f A ball with a radius of 14.5 inches.");

Happy coding!
