Multiple inclusion of header files in C/C++ programming can lead to compilation errors and undefined behavior. A header file typically contains function declarations, macros, and other definitions that are included in multiple source files. If a header file is included more than once in the same compilation unit, the compiler may attempt to process the same declarations and definitions multiple times, resulting in errors or unexpected behavior.
To avoid multiple inclusion of header files, the preprocessor directives #ifndef and #define are commonly used. These directives allow you to define a preprocessor macro that is only defined once, even if the header file is included multiple times. The general pattern is as follows:

UDP (User Datagram Protocol) is a connectionless network protocol that is used for transmitting data over the internet. Unlike TCP (Transmission Control Protocol), UDP does not provide any guarantees of delivery or order, but it is much faster and more efficient. This makes it ideal for applications such as online gaming, video streaming, and VoIP (Voice over IP).
To check UDP connectivity, you can use a variety of tools, such as ping, netstat, and traceroute. Ping is a simple tool that sends a series of ICMP (Internet Control Message Protocol) packets to a specified host and measures the time it takes for each packet to be returned. Netstat is a more advanced tool that can be used to display a list of all active TCP and UDP connections on your computer. Traceroute is a tool that can be used to trace the path of a packet from your computer to a specified host, and can be helpful in identifying any problems with connectivity.
