如何将字符串"brakemeup"转换为char [stringlength]数组？

#include<iostream>
#include<string>

int main() {
    std::string str = "brakemeup";
    int stringlength = str.length();
    char charArray[stringlength];

    for (int i = 0; i< stringlength; i++) {
        charArray[i] = str[i];
    }

    // 打印char数组
    for (int i = 0; i< stringlength; i++) {
        std::cout<< charArray[i] << " ";
    }

    return 0;
}
