Nextint () reads only numbers, but line breaks do not,
When nextint () is used, it must be a numeric character, followed by a line break and nextline (). It ends when the line Delimiter is read, and there is no information before the line separator,

Network Interconnection device Overview
When connecting a computer to a computer or workstation to a server, in addition to using the connection media, you also need some intermediary devices. What are the main intermediary devices? What role does it play? This is a concern in network design and implementation.
We divide commonly used connection devices into the following types:
I. network transmission media interconnection Device
When a network line is con
As the main connection device of LAN, Ethernet switches have become one of the fastest network devices widely used in applications. At the same time, with this rapid development, the functions of switches are constantly enhanced, the upgrade of the vswitch port and the continuous addition of the connection ports of various special devices to the vswitch also enrich the Interface Types of the vswitch, in order to give everyone a clear understanding of these interfaces, We have specially compiled
The ethernet switch is a very important device in the network. Many people may not know the data interface type of the Ethernet switch. It does not matter. After reading this article, you must have gained a lot, I hope this article will teach you more things. As the main connection device of LAN, Ethernet switches have become one of the fastest network devices widely used in applications. At the same time, with this rapid development, the functions of switches are constantly enhanced.

As the main connection device of LAN, Ethernet switch becomes one of the most popular network equipments, meanwhile, with this kind of rapid development, the function of the switch is continuously enhanced, then the replacement of switch port and the connection port of various special equipment are added to the switch continuously. This also makes the switch's interface types become very rich, in order to give you a clearer understanding of these interfaces, we have compiled a special article on
