Chapter 2: Problem 8

The character constant 'A' requires __________ byte(s) of memory, whereas the string constant "A"requires _________byte(s).

Short Answer

Expert verified
Answer: The character constant 'A' requires 1 byte of memory, while the string constant "A" requires 2 bytes of memory, due to the additional null character ('\0') at the end of the string.

Step by step solution

01

Understand Character Constants and String Constants

A character constant is a single character enclosed in single quotes (e.g., 'A'). Whereas, a string constant is one or more characters enclosed in double quotes (e.g., "A"). The important difference is that a string constant is automatically terminated with the null character ('\0').
02

Determine the memory requirement for the character constant 'A'

Character constants typically occupy 1 byte of memory. In this case, the character constant 'A' takes 1 byte of memory.
03

Determine the memory requirement for the string constant "A"

As we know, string constants are terminated with a null character ('\0') which is an extra character. In this case, the string constant "A" contains two characters: 'A' and null character ('\0'), and each character occupies 1 byte of memory. Therefore, the memory required for the string constant "A" is 2 bytes.
04

Conclusion

The character constant 'A' requires 1 byte of memory, whereas the string constant "A" requires 2 bytes.
