This is how I solved the first challenge

Objective-C Programming (2nd Edition) 3. Variables and Types
1 
#include <stdio.h>

int main(int argc, const char * argv[])
{

    // Declare variables
    float a = 3.14;
    float b = 42.0;
    
    double addition = a + b;
    printf("The sum is: %f . \n", addition);
    return 0;
}

I got confused because in the book it mentions /n and that it would be talked about later. However the %f was in the code for the Turkey project but no mention of it on that page and why its being used. just thought i would bring that to light.

Thanks for the example, after adding %f to the code it ran the code as expected.

iOS Mikey, same here, echoing your concern.

First time I ran it, got some message about there being two many functions for the %f to work properly. Unfortunately, I fixed the syntax before copying the error message, so I can’t tell exactly what I did to get that prompt. But pretty sure the %f was the culprit.
