iOS Objective-C Basics (Retired) Functional Programming in C Conditionals

Chain multiple if statements

I've tried combinations of else if and else to complete the following:

if ( i < 0 ){ printf("negative") } _____________ ( i > 0 ) { printf("positive"); } _____________ { printf("zero"); }

After rewatching the video, placing either ("else if", "else if") or ("else if", "else") as the answers should work, however I appear to be missing something.

Hi Darcy,

else if and then else worked for me. Maybe try again.

printf is a C function. If you are using Objective-C, use

NSLog(@"Hello World"); 
NSLog(@"i = %d",i);
NSLog(@"pi = %f",3.14);

See the NSLog documentation for how to format integer, floating point, and object values. Remember to add the '@' symbol before the double quotes.

As far as the conditionals go, make sure that your 'i' variable is initialized. That's all I can say. Please describe in greater detail what exactly is not working so that we may know what to look for.
