Question
StructuresThe following C declarationsstruct node { int i; float j;};struct node *s[10] ;define s to beOptionsAn array, each element of which is a pointer to a structure of type node.A structure of 2 fields, each field being a pointer to an array of 10 elements.A structure of 3 fields: an integer, a float, and an array of 10 elements.An array, each element of which is a structure of type node.
Solution
The correct option is "An array, each element of which is a pointer to a structure of type node."
Here's why:
The declaration struct node *s[10] ; defines s as an array of 10 elements, where each element is a pointer to a structure of type node.
In C, the * symbol is used to denote a pointer, and the [] symbols are used to denote an array. So, *s[10] means an array of 10 pointers.
The struct node part specifies the type of the pointers in the array. In this case, each pointer is pointing to a structure of type node, which is defined as having an integer i and a float j.
So, each element of the array s is a pointer that can point to a structure of type node.
