What is an array in C?

• A. A single variable that holds multiple values
• B. A collection of elements of different data types
• C. A collection of elements, all of the same data type
• D. A method for managing memory dynamically

Answer: (C)

An array in C is defined as a collection of elements, all of the same data type. This is fundamental to the concept of arrays, as they are designed to store a fixed-size sequential collection of elements, typically allowing access through indices. When an array is declared, it allocates memory to hold multiple values of the specified data type. For example, an array of integers can be declared as `int numbers[5];`, which creates an array that can hold five integers. The uniformity in data type ensures that operations such as indexing and iterating through the array can be implemented easily, with the compiler having a clear understanding of the data being manipulated. The other options suggest scenarios that do not match the characteristics of an array in C. An array is specifically not a single variable but rather a structure that allows for multiple values of the same data type to be held together in a contiguous block of memory, making the correct choice pivotal for understanding the foundational concepts of programming in C.
