using namespace std;

int main(){

    cout << "输出单个字符串" << endl;
    string str1 = "hello cpp!";
    for(int i=0; i < str1.size();i++){
        cout << str1[i] ;
    }
    cout << endl;

    cout << "输出字符串数组" << endl;
    string str2[10];
    for(int i=0;i < 10;i++){
        str2[i] = "loading ... ";
        cout << str2[i] << i <<endl;
    }

    return 0;
}

result
