Since the population of the Earth is around 7 billion (short scale), I would use either a long long integer that was 64 bits in length (if available) that would give me 18 digits of precision, or a double precision floating type that would give me 15 digits of precision.
In Visual Basic (VB), you can declare a text variable using the Dim statement followed by the variable name and the As String type. For example: Dim myText As String. You can then assign a value to it, like myText = "Hello, World!". This allows you to store and manipulate string data within your program.
A variable is used to store information. As an example say you are asking someone for their favorite food, and want to store the answer in a variable called favoriteFood: favoriteFood = input("What is your favorite food?") Now if you print the value of favoriteFood (using print(FavoriteFood)) you will see that it has been saved in that variable. You can store any type in a variable, such as number, a string, or even an object.
Array is used in C to store data of similar data type. Arrays are used when we want to store data in large quantities, e.g. if we want to store 100 numbers we have to declare 100 variables and remembering name of each variable is a very difficult task, here comes the array we can declare a single variable int num[100] now this variable can store 100 different or same numbers and can be accessed by referencing as num[0],num[1],num[2] and so on. So, we can say that to reduce efforts we use arrays.
In Java:You declare the variable like this:int sum;If you want to include decimals, change this to:double sum;To store an initial value, just use the assignment operator:sum = 0;You can combine this with the declaration:double sum = 0.0;To add something to the variable, for example the value of a variable called "x", use one of the following:sum = sum + x;sum += x;In Java:You declare the variable like this:int sum;If you want to include decimals, change this to:double sum;To store an initial value, just use the assignment operator:sum = 0;You can combine this with the declaration:double sum = 0.0;To add something to the variable, for example the value of a variable called "x", use one of the following:sum = sum + x;sum += x;In Java:You declare the variable like this:int sum;If you want to include decimals, change this to:double sum;To store an initial value, just use the assignment operator:sum = 0;You can combine this with the declaration:double sum = 0.0;To add something to the variable, for example the value of a variable called "x", use one of the following:sum = sum + x;sum += x;In Java:You declare the variable like this:int sum;If you want to include decimals, change this to:double sum;To store an initial value, just use the assignment operator:sum = 0;You can combine this with the declaration:double sum = 0.0;To add something to the variable, for example the value of a variable called "x", use one of the following:sum = sum + x;sum += x;
A strongly typed programming languages is one that requires the type of a variable to be explicitly stated. C is a strongly typed language. You must declare the type of data a variable will store for C to interpret it: int myVariable;myVariable = 25; Perl is a loosely typed language. There is no need to declare the variable type before using it: $myVariable = 25;$myVariable = "A String.";
double variable_list;
double variable_list;
In pseudocode, you can declare a variable holding real numbers by specifying the variable name followed by its type. For example, you might write REAL numberVariable; or DECLARE numberVariable AS REAL;. This indicates that numberVariable will store a real number value. You can then assign a value to it using an assignment statement, such as numberVariable = 3.14;.
Declare a string variable to store the message value.For example:Dim message As String = "Happy New Year"Console.WriteLine(message)message = "Merry Christmas"Console.WriteLine(message)

NO. Variable capacitory can store a small charge

You can declare them one by one. However, if you want to store lots of related data, you may want to consider using an array, where you use a single variable name (for example) for 1000 different items, and a number called an index to access the individual items.
