Question

What are some similarities and differences between string literals(read-only) and arrays of characters(read-write strings)?

Answer 1

String literals and arrays of characters are both used to represent text data but have different characteristics. String literals are read-only and fixed, while arrays of characters are read-write and can be modified. The former can be considered static characters, while the latter can be considered dynamic characters.

Step-by-step explanation:

String literals and arrays of characters, also known as read-only and read-write strings, are both ways to represent sequences of characters in programming languages. Here are some similarities and differences between them:

1. Similarities: Both string literals and arrays of characters are used to store and manipulate text data. They can both be accessed using index-based notation to retrieve individual characters or perform string operations on them.
2. Differences: String literals are fixed and cannot be modified at runtime, making them read-only. On the other hand, arrays of characters can be modified, allowing for read-write functionality.
3. Static vs Dynamic: String literals can be considered static characters as they do not change. Arrays of characters, on the other hand, can be considered dynamic characters as their contents can be altered programmatically.
