如何在C++中查找和替换输入中的另一个字符串？

#include <iostream>
#include <string>

int main() {
    std::string input = "Hello World";
    std::string search = "World";
    std::string replace = "Universe";

    // 查找并替换字符串
    size_t pos = input.find(search);
    if (pos != std::string::npos) {
        input.replace(pos, search.length(), replace);
    }

    std::cout << input << std::endl;

    return 0;
}
