c++ - What is meant by char temp[3]="";?

Question

Normally in C++, character arrays are initialized in the following way,

char example[5]="cat";

What if you initialize it with "" (just a double quotes without spaces)?
What will be the elements in the character array after initialization?

Answer 1

The declaration

char    temp[3] = "";

is same as

char    temp[3] = {0};
                  // `` ascii value is 0

remember remaining elements of half initialized array initialized with 0.

Point :char temp[3] = "" is easy to type(means writing), so its preferable.

Look even compare it with this declaration char temp[3] = {''}; (it need more chars to type) Whereas in char temp[3] = ""; is simple (even no type mismatch - int/char).
