有没有办法在Windows上以C++编程方式设置环境路径？

#include<iostream>
#include<string>
#include<windows.h>

using namespace std;

int main() {
    string path = "C:\\path\\to\\add;";
    string currentPath = getenv("PATH");
    if (currentPath.length() > 0 && currentPath[currentPath.length() - 1] != ';') {
        currentPath += ";";
    }
    currentPath = path + currentPath;
    if (SetEnvironmentVariable("PATH", currentPath.c_str())) {
        cout << "Environment path has been updated successfully."<< endl;
    } else {
        cout << "Failed to update environment path."<< endl;
    }
    return 0;
}
