从文件中读取数据时的无限循环

问：

我正在尝试从文件中读取数据。有三行。我所做的是下面。问题是（文件存在）在读取文件时它是无限循环。我观察到程序在到达文件末尾之前不会逐行移动。我的代码中有什么错误？

法典：

if (desktops == NULL) {
        printf("\n No such file.\n");
    } else{
            printf("\nFile exists. Reading\n");

        while(!feof(desktops)){

            if(numberOfObjects== 0)
            {
                 fscanf(desktops,"%fl %fl %fl %fl %d %s %s %d\n",&height,&length,&width,&processorClock,&idNumberSerial,&processorTypeChars,&nameInNetworkChars,&ID);
                 nameInNetwork = string(nameInNetworkChars);
                 processorType = string(processorTypeChars);
                // nameInNetwork = "test";
                 glowaListyObjektow = new Desktop(height,length,width,processorClock,idNumberSerial,processorType,nameInNetwork,ID);
                 iterator = glowaListyObjektow;


                 iterator->previousObject = NULL;
                 iloscObiektow++;
                 nameInNetwork.clear();
                 processorType.clear();
            }
            else if(numberOfObjects> 0)
            {
                fscanf(desktops,"%fl %fl %fl %fl %d %s %s %d\n",&height,&length,&width,&processorClock,&idNumberSerial,&processorTypeChars,&nameInNetworkChars,&ID);
                nameInNetwork = string(nameInNetworkChars);
                processorType = string(processorTypeChars);
                // nameInNetwork = "test";
                iterator->nextObject = new Desktop(height,length,width,processorClock,idNumberSerial,processorType,nameInNetwork,ID);


                iterator->nextObject->previousObject = iterator;
                iterator = iterator->nextObject;
                iloscObiektow++;
                 nameInNetwork.clear();
                 processorType.clear();
                // nameInNetworkChars = NULL;
            }



            cout<<"reading line"<<endl;
// Here line above is printed infinitely.
        }
            fclose(desktops);
    }
