Question about arrays

[hellworld136]

In the code below, I'm asked what the function fo(int c[], int d[]) will do. The function below has 3 arguments however, so I'm unsure if it's a typo.

If it is not a typo, am I correct in saying it will not compile since it has only two arguments?

If it is a typo, am I correct in saying the function below will put the array c and reverse it into d? i.e. if c=1 2 3 4 5, d=5,4,3,2,1 after the function call.

void fo(int c[], int d[], int e){
    for(int i=0;i<e;i++){
        d[e-1-i]=c[i];
    }
}

How would you know when to stop if you weren't given a size?

The question asks what does the function fo(int c[], int d[]) do(I assume not having int e is a typo), so couldn't I say it puts the reverse of the array C into array D? Should I also say, assuming c and d are equal, and e is >0?

[giblit]

Yes it reverses the array.

Should I also say, assuming c and d are equal, and e is >0?

the former are you saying the size is the same? If so they should be. The latter yeah it would make sense that the size of the container be positive.
