/* The program has been modified to output the longest word in an English conversation through compilation. I wrote exactly according to your idea, but I want to say that your idea is not very good. It took me more than 20 minutes, and vc6.0 compiled without errors and warnings! See you write the statement of the function in the main function, it shouldn't take long to learn. It's good for beginners to have their own ideas, and it doesn't matter if it's complicated. But to be honest, this program is a bit complicated. You should pay more attention to the basics, completely out of kindness to remind. Because beginners have to take many detours in learning, they can ignore the above suggestions! Hmm. How interesting
I have written a program before, which is to change all spaces into' \0', dynamically apply for memory to store every word, and simulate the way the command line obtains parameters.
I hope I can help you, come on! */
