Assigning vs initialising structure variables

Question

I'm initialising an array of structures in main(); I get an error, when I declare and assign them separately.

This is my code snippet from main();

struct item newitem[10];
newitem[0]={1,"pen",5,10};
struct item new2= {2,"ygh",9,0};

This is the error I get on line 2. The line 3 works fine, however.

[Error] expected expression before '{' token

What could be the reason?

If the third line is supposed to initialize `newitem[1]` or `newitem[2]`, it fails to do so. Why not include the initializer for `newitem[0]` in the definition of `newitem`, which has the additional merit of initializing (to zeros) all the other elements of the array of structures. `struct item newitem[10] = { { 1, "pen", 5, 10, }, };` — Jonathan Leffler, Apr 24 '18 at 05:23

You have to use compound literal:

newitem[0] = (struct item) {1, "pen", 5, 10};
