What happens if the number of values to be initialized is more than the size of the array in C?

The array size is dynamically adjusted

An error is reported during compilation (correct)

The excess values are truncated

The compiler allocates additional memory locations automatically

If an array is partially initialized in C, what value are the uninitialized elements assigned?

Values from a predefined list

Random values

Values based on the memory address

Default values (e.g., 0) (correct)

In C, what happens when an array is initialized with all elements as 0?

Memory locations remain uninitialized

Compiler initializes all elements to 1

Compiler throws an error

All elements are set to zero by the compiler (correct)
