** WRITTEN IN C

The word "issue'' means either a compilation error, undefined behavior or a memory leak. For sake of space, #include's have been omitted in the code examples: assume that any necessary ones exist.

Does the following code have any errors or undefined behavior? If yes, what is the issue? If not, what will be the output of the following code? In either case, explain your answer in detail. void allcaps (char *str, int len) f for (int i = 0; i len ; i++) { str [i] ('A' 'a'); += - int main) f char message []-"Hello, world!"; allcaps (message, sizeof (message)); printf ("%s ", message)
