How to find the last index value of a string in Golang?
LastIndex() is a built-in function of strings package in Golang. This function is used to check the index of the last occurrence of a specified substring in a given original string. If the substring is found in the given string, then it returns its index position, starting from 0; otherwise it returns "-1".SyntaxThe syntax of LastIndex() is −func LastIndex(str, substr string) intWhere, str is the string inside which we need to search, andsubstr is the substring that we want to search inside the str.Example 1Let us consider the following example −package main import ( "fmt" "strings" ) func ...
Read Morestrings.IndexByte() Function in Golang
IndexByte() is an inbuilt function of strings package in Golang. This function returns the index of the first occurrence of a character in a given string. If the character is found, then it returns its index, starting from 0; else it returns "-1".Syntaxfunc IndexByte(str string, chr byte) intWhere, str – It is the original string.chr – Character (byte) to be checked in the string.Example 1Let us consider the following example −package main import ( "fmt" "strings" ) func main() { // Initializing the Strings m := "IndexByte String Function" n := "Golang IndexByte String Package" ...
Read Morestrings.IndexAny() Function in Golang
strings.IndexAny is a built-in function in Golang which is used to get the index of the first instance of any Unicode code point from the input substring. If the substring is found, it returns the position starting from 0; else it returns -1.Syntaxfunc IndexAny(s, chars string) intWhere, s – The original given string.chars – It is the substring that is to be checked in the given string.Example 1Take a look at the following example.package main import ( "fmt" "strings" ) func main() { // Defining the Variables var str string var charstring string var ...
Read MoreHow to find the Index of a string in Golang?
Strings.Index is a built-in function in Golang that returns the index of the first instance of a substring in a given string. If the substring is not available in the given string, then it returns -1.SyntaxThe syntax of Index() is as follows −func Index(s, substring string) intWhere, s – Original given stringsubstring – It is the string whose Index value we need to findExample 1Let us consider the following example −package main import ( "fmt" "strings" ) // Main function func main() { // Initializing the Strings x := "Learn Golang on Tutorialspoint" ...
Read MoreReplace() vs ReplaceAll() in Golang
ReplaceAll() function in Golang replaces all the occurrences of a given substring with a new value. In contrast, Replace() function is used to replace only some characters in a string with a new value. It replaces only a specified "n" occurrences of the substring.SyntaxThe syntax of ReplaceAll() is as follows −func ReplaceAll(s, old, new string) stringWhere, s is the given stringold is the string which we want to replace, andnew is string which will replace the old string.Example 1Let us consider the following example −package main import ( "fmt" "strings" ) func main() { // Initializing ...
Read MoreHow to check if a string starts with a specified Prefix string in Golang?
The HasPrefix() function of string class in Golang is used to check whether a given string begins with a specified Prefix string or not. It returns True if the given string begins with the specified prefix string; otherwise it returns False.Syntaxfunc HasPrefix(s, prefix string) boolWhere x is the given string. It returns a Boolean value.ExampleIn this example, we are going to use HasPrefix() along with an if condition to check wheter the two defined variables are starting with the same Prefix string or not.package main import ( "fmt" "strings" ) func main() { // Initializing ...
Read MoreHow to use the Fields() function in Golang?
The strings package of Golang provides a Fields() method, which can be used to split a string around one or more instances of consecutive whitespace characters.The Fields() function splits a given string into substrings by removing any space characters, including newlines. And it treats multiple consecutive spaces as a single space.Syntaxfunc Fields(s string) []stringWhere s is the string parameter.ExampleLet us consider the following example −package main import ( "fmt" "strings" ) func main() { // Initializing the Strings string1 := " The Golang Programming Language " // Display the Strings fmt.Println("Input String:", string1) ...
Read MoreWhat is the EqualFold function in Golang?
The EqualFold() function in Golang is an inbuilt function of strings package which is used to check whether the given strings (UTF-8 strings) are equal. The comparison is not case-sensitive. It accepts two string parameters and returns True if both the strings are equal under Unicode case-folding (i.e., case-insensitive), False otherwise.Syntaxfunc EqualFold(s, t string) boolWhere s and t are strings. It returns a Boolean value.ExampleThe following example demonstrates how to use EqualFold() in a Go program −package main import ( "fmt" "strings" ) func main() { // Intializing the Strings R := "Welcome to Tutorialspoint" ...
Read MoreHow to count the number of repeated characters in a Golang String?
Count() is a built-in function is Golang that can be used to count the number of non-overlapping instances of a character/string in a string.Syntaxfunc Count(s, sep string) intWhere, s – Original Stringsep – Substring which we want to count.It returns an Integer value.ExampleThe following example demonstrates how you can use the Count() function in a Go program.package main import ( "fmt" "strings" ) func main() { // Initializing the Strings x := "Golang Programming Language" y := "Language" // Display the Strings fmt.Println("First String:", x) fmt.Println("Second String:", y) ...
Read MoreHow to use Contains() function in Golang?
Golang has a set of built-in string functions that we can utilize to perform different types of operations on string data. Contains() is such a function that can be used to search whether a particular text/string/character is present in a given string. If the text/string/character is present in the given string, then it returns True; else it returns False.Syntaxfunc Contains(s, substr string) boolWhere, s is the original string and substr is the string which is to be checked with the original string.ExampleThe following example demonstrates how Contains() works −package main // importing fmt and strings import ( "fmt" ...
