Character Array vs. String Array: Know the Difference
By Shumaila Saeed || Published on February 20, 2024
Character Array is a sequence of characters, each occupying one array element. String Array is an array where each element is a string (sequence of characters).
Key Differences
A character array is a linear collection of characters, accessible individually by indexing, often representing a single string. A string array, however, contains multiple strings, with each string being an individual element in the array.

Character arrays are often used to manipulate individual characters within a string, useful in low-level string processing. String arrays are utilized to store and manipulate multiple strings, common in scenarios like handling lists of names or sentences.

In a character array, each element is a single character, typically consuming one byte. In a string array, each element is a reference to a string, which itself could be an array of characters.

Functions that operate on character arrays often deal with characters' ASCII values, while those for string arrays handle entire strings, enabling operations like concatenation, comparison, and searching at the string level.

Character arrays offer fine-grained control for character-level operations but can be complex for handling entire strings. String arrays are more straightforward for handling collections of text, like sentences or paragraphs, and provide higher-level string functions.
