Explain the use of Go's string types and operations for working with string data?
The use of Go's string types and operations for working with string data are as follows:-
In Go, a string is a sequence of Unicode characters represented by a series of bytes. Strings are immutable, meaning that once a string is created, its contents cannot be changed. This means that any operation that appears to modify a string actually creates a new string with the modified content.
Go provides several built-in functions and operators for working with strings, including:
String literals: In Go, a string literal is a sequence of characters enclosed in double quotes, like "hello world". String literals can contain any Unicode character, including escape sequences like \n for newline and \t for tab.
String concatenation: Go provides the + operator for concatenating two or more strings together, like "hello" + "world" = "helloworld".
String indexing: Go allows you to access individual characters in a string using square brackets, like myString[0] to get the first character in the string.
String slicing: Go allows you to extract a substring from a string using a slice expression. For example, myString[2:5] would return the characters from positions 2 through 4.
String length: Go provides the len() function to get the length of a string in bytes.
String comparison: Go provides the == and != operators to compare two strings for equality. The comparison is case-sensitive and uses Unicode code points.
String conversion: Go provides the strconv package for converting between strings and other data types, like numbers and booleans.
Overall, Go's string types and operations provide a powerful set of tools for working with string data.
