Question

我有数据通过popen进入我的缓冲区（进程数据，而不是文件）。每七个记录是一个新的集[0-6]。我试图打印出数组行/元素值，但我的循环似乎是循环遍历每个字符而不仅仅是每一行？

代码：

char* Data(){

        char buff[BUFSIZ];
        FILE *fp = popen("php order.php 155", "r");
        std::string::size_type sz;
        while(fgets(buff, sizeof buff, fp) != NULL)
        {
                const char * cstr2 = buff;
                for(int i = 0; i < 6; ++i){
                        if(i == 0){
                                std::cout << "value 1: " << cstr2[0] << endl;
                        }
                        if(i == 1){
                                std::cout << "value 2: " << cstr2[1] << endl;
                        }
                        if(i == 2){
                                if (!strcmp(cstr2, "Buy\n")) {
                                        printf("Found String!\n");
                                }
                        }
                }

        }
}

如何更正我的循环以在if语句中显示const char数组中的各个行/元素，类似于上面的代码？

const char数组流输出循环错误，输出错误
