To replace characters in a string, you can use the std::replace function or implement your own replacement function. Here is an example using the std::replace function:

#include <iostream>
#include <algorithm>
#include <string>

int main() {
    std::string str = "Hello, World!";
    
    std::replace(str.begin(), str.end(), 'l', 'x');
    
    std::cout << str << std::endl; // 输出Hexxo, Worxd!
    
    return 0;
}

This code replaces all instances of the character ‘l’ with ‘x’ in a string. If multiple characters need to be replaced, the std::replace function can be called multiple times. Alternatively, for more complex replacements, consider implementing a custom replacement function.
