char s[] = "Hello";
and this...?
char *s = "Hello";
Aren't they just two ways of doing the same thing? That is, of assigning the string "Hello" to the string variable s? Well, no. In fact, these two assignments are very different things. If you have moved to C from another language such as Java, Python, C# or Ruby, making sense of arrays, strings, pointers and addresses is likely to be one of the biggest challenges you'll face. Here's a video I made that should help out.
