正则表达式检测用于&while循环的半冒号终止C++

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

int main() {
    std::string input = "&while(true);";
    std::regex pattern("&while.*?;");

    if (std::regex_search(input, pattern)) {
        std::cout << "Found &while loop with semicolon termination."<< std::endl;
    } else {
        std::cout << "No &while loop with semicolon termination found."<< std::endl;
    }

    return 0;
}
