Removing punctuations from a given string

Given a string, remove the punctuation from the string if the given character is a punctuation character as classified by the current C locale. The default C locale classifies these characters as punctuation:

!"#$%&'()*+,-./:;?@[\]^_`{|}~

Examples:

Input : %welcome' to @geeksforgeek<s
Output : welcome to geeksforgeeks

Input : Hello!!!, he said ---and went.
Output : Hello he said and went

Recommended: Please try your approach on {IDE} first, before moving on to the solution.

A loop is designed that goes through a list composed of the characters and punctuations of that string, removes the punctuation and then joins them.

C++

// CPP program to remove punctuation from a given string 
  
#include <iostream> 
using namespace std; 
  
int main()  
{ 
    // input string 
    std::string str = "Welcome???@@##$ to#$% Geeks%$^for$%^&Geeks"; 
  
    for (int i = 0, len = str.size(); i < len; i++) 
    { 
        // check whether parsing character is punctuation or not 
        if (ispunct(str[i])) 
        { 
            str.erase(i--, 1); 
            len = str.size(); 
        } 
    } 
      
    // print string without punctuation 
    std::cout << str; 
    return 0; 
} 

Java

// Java program to remove punctuation from a given string 
  
public class Test 
{ 
    public static void main(String[] args) 
    { 
        // input string 
        String str = "Welcome???@@##$ to#$% Geeks%$^for$%^&Geeks"; 
          
        // similar to Matcher.replaceAll 
        str = str.replaceAll("\\p{Punct}",""); 
          
        System.out.println(str); 
    } 
      
}

    # traverse the given string and if any punctuation 
    # marks occur replace it with null 
    for x in string.lower(): 
        if x in punctuations: 
            string = string.replace(x, "") 
  
    # Print string without punctuation
