Checking internet connection in C is a crucial task for any program that relies on network connectivity. It allows the program to determine whether it has access to the internet and, if so, the quality of the connection.
There are several ways to check internet connection in C. One common method is to use the `ping` function. Ping sends a series of packets to a specified IP address or hostname and waits for a response. If a response is received, it means that the computer is able to communicate with the specified destination. The time it takes for the packets to be sent and received can also be used to estimate the quality of the connection.
