C++ Error

Question

Can someone help?

The following code outputs an error and I'm not sure how to fix it.

char arr [1] = {};
arr [0] = char "A";

Answer 1

Char is ' ' not " ".
And, I’m not sure, but a char is not an array, because there’s only one character

Answer 2

Because "A" is a char array with two elements and 'A' is a single char.
char name[] = "Zack";
and
char name[] = {'Z', 'a', 'c', 'k', '\0'}
are the same 5 character arrays.

Answer 3

Because that character is used to terminate "strings". Otherwise, they would never end and would print all of memory.

Answer 4

char x[] = "Zack";
while (*x != '\0') {
cout << *x;
x++;
}
is identical in concept to:
char x[] = "Zack";
cout << x;

The second is faster as the loop is within the function cout uses instead of multiple calls to the function.

Answer 5

Why '\0' at the end ?

Answer 6

Ok thanks

Answer 7

yes it was ' '. I also had to remove the second "char" for it to work. But why should ' ' and " " be different?
