How do you declare a struct with two integer fields 'x' and 'y' and create a typedef alias 'Point'?

• A. typedef struct { int x; int y; } Point;
• B. struct Point { int x; int y; }
• C. typedef Point { int x; int y; } Point;
• D. typedef struct { int a; int b; } Point;

Answer: (A)

The idea being tested is how to define a new struct type and give it a convenient alias in one step. The correct approach uses typedef with an anonymous struct that contains the required fields, and assigns the alias Point. Specifically, typedef struct { int x; int y; } Point; creates a new type named Point that is a struct with two integers, x and y. This lets you write code like Point p; to declare a variable, without needing to say struct each time.

The other options don’t fit fully: declaring a struct with a tag named Point without a typedef doesn’t create the alias Point you’d use directly as a type; you’d have to refer to it as struct Point. The third option uses invalid syntax. The fourth assigns different field names, not x and y.
