Datatype in C MCQs Exercise I

An array, on the other hand, is not a primitive data type. It's a composite data structure that stores a collection of elements of the same data type. Each element in an array has a specific index or position, allowing you to access and manipulate individual elements within the collection. Arrays provide a way to organize and manage multiple related values under a single name.

A char data type typically stores signed integers and covers the range from -128 to 127. This holds true across most programming languages. It uses 1 byte of memory, and half of that goes to representing the sign. If you need non-negative values, use unsigned char (ranging from 0 to 255). While some systems might use 2 bytes for char, the standard representation and common range is -128 to 127.

The size of a char data type can vary depending on the system and compiler, but it is typically 1 byte. This allows it to represent integer values from -128 to 127. However, some systems might use 2 bytes for char, extending the range to -32768 to 32767. If you need to store unsigned characters (non-negative values), you can use the unsigned char type, which typically has a range of 0 to 255.
