Return array in a function

Question

I have an array int arr[5] that is passed to a function fillarr(int arr[]):

int fillarr(int arr[])
{
    for(...);
    return arr;
         


        

Answer 1

to return an array from a function , let us define that array in a structure; So it looks something like this

struct Marks{
   int list[5];
}

Now let us create variables of the type structure.

typedef struct Marks marks;
marks marks_list;

We can pass array to a function in the following way and assign value to it:

void setMarks(int marks_array[]){
   for(int i=0;i

We can also return the array. To return the array , the return type of the function should be of structure type ie marks. This is because in reality we are passing the structure that contains the array. So the final code may look like this.

marks getMarks(){
 return marks_list;
}
