How to replace the characters !@#$%^*_+\= in a string using RegEx with C++

Answer 1

#include <iostream>
#include <regex>
#include <string>

int main() {
    std::string input = "The!quick@brown#fox$jumps%^over*_the+\\lazy=dog.";
    std::regex pattern("[!@#$%^*_+=\\\\]"); 
    std::string replacement = " ";

    // Perform regex replacement
    std::string result = std::regex_replace(input, pattern, replacement);

    std::cout << "Original: " << input << std::endl;
    std::cout << "Modified: " << result << std::endl;
}


/*
