What are the strings

String is a data type, it can be any text, including letters, numbers, symbols, etc. Strings can be composed of different characters such as spaces, punctuation marks, numbers, etc. In programming, strings are usually enclosed in quotes, such as single quotes, double quotes, or backticks.

In most programming languages, strings are immutable, which means that once a string is created, its value cannot be changed. However, some programming languages, such as Python, allow modifying the value of a string.

Strings can be used for a variety of purposes, such as:

• Saving and processing text data
• Formatting output
• Parsing and manipulating data
• Input/output operations
• File name and path processing
• URL and URI processing in network programming, etc.
