Why does Xcode ask me for ";"?

Hello, I am pretty much certain that I am the one coins something wrong here but I cannot explain myself why is Xcode prompting me with the error in this screenshot.

I am starting to think that programming might not be for me...

Just as John W mentioned:

#include <stdio.h>

typedef struct {
    float center[3];
    float radius;
} Sphere;

Sphere makeSphere (float *c, float r);


int main()
{


}

Sphere makeSphere (float *c, float r)
{

        Sphere sphere;
        sphere.center[0] = *c[0];
        sphere.center[1] = *c[1];
        sphere.center[2] = *c[2];

        sphere.radius = r;
        return Sphere;
}

yes you are just missing ; at the end of the statement !

You are trying to define a function inside a function. Just move the whole thing outside of main() and it should fix it.

Just put a " ; " at the end, does it go away?

I believe the construct itself shouldnt have a ";" and if a do put a ";" it invalidarea everything beneath. In the example from the video, there is no ";" before opening the querly braces

try this

#include <stdio.h>

typedef struct {
    float center[3];
    float radius;
} Sphere;

Sphere makeSphere (float *c, float r);


int main()
{
}

Sphere makeSphere (float *c, float r)
{

        Sphere sphere;
        sphere.center[0] = *c[0];
        sphere.center[1] = *c[1];
        sphere.center[2] = *c[2];

        sphere.radius = r;
}
