Initializing struct structure member consisting of an int and a char pointer?

Question

Here are the structure declarations:

typedef struct line { int width; char *theLine; } Line; typedef struct screen { int width; int height; Line *theScreen; } Screen;

Here is what I am using to try an initialize the Screen structure:

int main() { Screen b = {20, 40, {40, "-"}}; }

When I compile the above the result is:

warning: braces around scalar initializer [enabled by default] Screen b = {20, 40, {40, "-"}}; ^

What am I doing wrong in the structure initialization? Also, once I am able to compile the code above, how would I access each member of the Line variable withing the struct screen? Any help is greatly appreciated, thank you.

You've defined the 3rd member as a pointer. With Line theScreen; instead of Line *theScreen;, your initialization code would work.

Thank you for the reply. I realized this as well, but I believe it to be part of the assignment to make it work with a pointer.Even though it seems inefficient.

@WillyFiallo Screen b = {20, 40, &(Line){40, "-"}};

(^One way to allocate the Line struct and get a pointer to it)
