What is short int in C programming?
a) A data type that usually occupies 4 bytes
b) A data type that usually occupies 8 bytes
c) A data type that usually occupies 2 bytes
d) A data type that usually occupies 1 byte
Answer:
c) A data type that usually occupies 2 bytes
Explanation:
short int in C is a data type that typically occupies 2 bytes of memory, which is 16 bits. The exact size can vary depending on the system architecture, but on most systems, a short int is 2 bytes. This data type is used when you want to save memory and you know the value range will be within the limits of a 2-byte integer.
Understanding data types like short int is important for optimizing memory usage and ensuring that your program runs efficiently, especially in memory-constrained environments.
