Assigning strings to arrays of characters

Question

I am a little surprised by the following.

Example 1:

char s[100] = \"abcd\"; // declare and initialize - WORKS

Example 2:

Answer 1

1    char s[100];
2    s = "hello";

In the example you provided, s is actually initialized at line 1, not line 2. Even though you didn't assign it a value explicitly at this point, the compiler did. At line 2, you're performing an assignment operation, and you cannot assign one array of characters to another array of characters like this. You'll have to use strcpy() or some kind of loop to assign each element of the array.
