what it really means?
if it gets total length of the array 5 ,why dont it accept the input with in the array size?

Answer 1

First of all, int[5] = {1,2,3} is missing the variable name. So it's a syntax error.
Also, there's difference between array declaration and array initialization. If initialized with 3 values, then the compiler understands that the size is also 3. See the attached code:

Answer 2

needs to look somthing like this

but depends what type of array your doing

int [][] x = {{1,2,3},{4,5,6}};
