Variable Is a location in the computer's memory where a value can be stored for use by a?
program. Each variable has a name that serves as an identifier, allowing the program to reference and manipulate the stored value. Variables can hold different types of data, such as integers, strings, or booleans, and their values can be changed throughout the program's execution. This flexibility makes variables essential for managing data and controlling the program's behavior.

What is poiner value in c?
In c a pointer is a variable that points to or references a memory location in which data is stored. Each memory cell in the computer has an address that can be used to access that location so a pointer variable points to a memory location we can access and change the contents of this memory location via the pointer. Pointer declaration A pointer is a variable that contains the memory location of another variable. The syntax is as shown below. You start by specifying the type of data stored in the location identified by the pointer. The asterisk tells the compiler that you are creating a pointer variable. Finally you give the name of the variable. type * variable name Example: int *ptr; float *string;
What is a use of dereferencing operator?
A pointer variable contains the address to some memory location. "Dereferencing" the pointer means getting the value stored at that memory location.
Why should variables be declared in a programming?
a variable should in a programming because as the definition implies it is a named location in the memory where all the data is to be stored
Who is the address operator?
The address operator, often represented by the ampersand symbol (&) in programming languages like C and C++, is used to retrieve the memory address of a variable. By applying the address operator to a variable, you can obtain a pointer that points to the location in memory where that variable is stored. This is essential for pointer manipulation and dynamic memory management in these languages.
Where the variables are stored in the computer?
Variable stored in the memory block inside the RAM. whenever we declare a variable it would take space in main memory and consume it's size from RAM.
What are the components of a variable?
A variable typically consists of a name, a data type, a value, and a memory location where the value is stored. The name is used to reference the variable in the code, the data type defines the type of data the variable can hold, the value is the actual data stored in the variable, and the memory location is where the value is stored in the computer's memory.

What is the named storage location in the computer's memory?
a variable is a named storage location in a computers memory for holding a peice of information i have computer seince as my major ;)
What is a variable made up of?
A variable is made up of a name (identifier) that represents a value stored in a computer's memory. It consists of a memory location where data can be stored and manipulated in a program. The value assigned to a variable can change during program execution.
What is a use of dereferencing operator?
A pointer variable contains the address to some memory location. "Dereferencing" the pointer means getting the value stored at that memory location.
What is pointer why you use pointer?
Pointer is a variable that stores the address of another variable. Since pointer is also akind of variable, thus pointer itself will be stored at a different memory location.
Why should variables be declared in a programming?
a variable should in a programming because as the definition implies it is a named location in the memory where all the data is to be stored
What is a function of a variable?
A variable is a named memory address in which a value may be stored and mutated.
Where is constant variable stored?
Random Access Memory (RAM)

Where does global variables stored in C?
It depends entirely on what platform you are using. In an embedded environment, for instance global/static variables go into different RAM memory segments depending on whether or not they are initialised. constants are often left in ROM automatic variables are normally placed of the stack of the currently running task but not always.
