删除字符串中的某些字符

string = "Hello, World!"
new_string = string.replace(",", "").replace(" ", "")
print(new_string)  # Output: HelloWorld!

var string = "Hello, World!";
var new_string = string.replace(/[, ]/g, "");
console.log(new_string);  // Output: HelloWorld!

#include <iostream>
#include <string>
using namespace std;

string removeChars(string str, string charsToRemove) {
    string result = "";
    for (char c : str) {
        if (charsToRemove.find(c) == string::npos) {
            result += c;
        }
    }
    return result;
}

int main() {
    string str = "Hello, World!";
    string charsToRemove = ", ";
    string newStr = removeChars(str, charsToRemove);
    cout << newStr << endl;  // Output: HelloWorld!
    return 0;
