Declare and initialize 2D array in java using two statements- one to declare variable the other to initialize elements?
I'm not sure what you're asking. Do you mean when you declare/instantiate an array like this?
int[][] arr;
arr = {{1, 2, 3},{4, 5, 6}};
I think that's right.
***********************************
THIS IS INCORRECT
because you can assign constant values to array only at time of initialization.
Therefore above code will throw an error.
Correct way is:
int[][] arr = {{1, 2, 3},{4, 5, 6}};
thanx ..

Declare a numerical variable precise and initialize it to the value 1.09388641?
double precise = 1.09388641;
How do you initialize an array at compile time in c?
In C, you can initialize an array at compile time by specifying its elements within curly braces during declaration. For example, you can declare and initialize an integer array like this: int arr[] = {1, 2, 3, 4, 5};. The size of the array can be omitted, and the compiler will automatically deduce its size based on the number of elements provided. Additionally, you can specify the size explicitly, such as int arr[5] = {1, 2, 3, 4, 5};.
Is it possible to declare a variable with abstract keyword?
yes
Why all variables are declared with in the function?
It is not necessary to to declare variables inside the function in C. If you declare a variable inside a function, the variable becomes local for the function and another variable of same name can be declared in any other function, but you can not use the variable declared in other function. When you declare any variable outside the function body then the variable becomes global and can be used in any function of the program. Note: errno is an example for a variable declared outside any function.
Can you declare any variable above preprocessor directive?
Yes.

How do you declare and initialize constant arrays?

How do you find factorial 5 in C programming?
to find the factorial we declare a variable n and initialize its value to 1 initiate a loop for example a for loop and multiply the numbers upto 5 code:- for(i=1,n=1;i<=5;i++) { n=n*i; }

What is variable declarations?
A variable declaration is a math or programming term. A variable is an unnamed component. In the problem the wording will declare what the value of the variable is.

How can I declare a double precision variable in Fortran?
To declare a double precision variable in Fortran, you can use the "real(kind8)" declaration. This specifies that the variable should be of double precision, which is typically 8 bytes in size.
Can you declare SQLCODE in working storage section?
No, you cannot declare SQLCODE in the Working-Storage Section of a COBOL program. SQLCODE is a special variable used to indicate the success or failure of SQL statements and is automatically provided by the database interface when executing SQL commands. Instead, it is typically referenced directly after executing SQL statements without needing an explicit declaration in the Working-Storage Section.
When do you declare a variable?
You declare a variable when you create it by specifying its datatype and name in a programming language. This tells the compiler or interpreter to allocate memory for the variable. Variables must be declared before they can be used in most programming languages.
