What is pointer?
pointer r the variables created in RAM which store the address of a another variable
How are we going to use pointer in a program?
A pointer is a variable used specifically to store a memory address. We say the variable "points to" the memory address because we can dereference the pointer to access the value stored at that address. The pointer's type determines how that dereferenced value will be interpreted. Being a variable, we can change the stored address and thus change which value we point at. This makes it possible for the same variable to refer to different objects in memory, which includes other pointer variables.
Why pointers in c?
Pointers are variable that are used to point to the address of another variable. OR Pointers can also me defined as variables that are used to store address of another variable. They provide means through which the memory location of variable can be directly accessed and they also support dynamic allocation routines.
What is a ponters in c-programming?
with the help of pointers we able to store the memory location of any variable. In c the pointer variable is use to store the memory location of any variable. The pointer variable is define as a simple variable but in pointer variable use a special "*" character at the left most side of name of pointer variable. If any variable name have * it means it is a pointer variable it hold the memory location of variable.
Is it true or false that assigning an address to a pointer variable is valid operation?
Pointers are meant to store adresses.
Is class a pointer?
No. In computer programming, a class is a data type while a pointer is a variable that can store a memory address.
How do pointer work in c program?
Pointer can be defined as variable that is used to store memory address , usually the location another variable in memory. Pointers provide a means through which memory location of a variable can be directly accessed.
Can variable resistors store electrical charge?
NO. Variable capacitory can store a small charge
Where are store static variable in memory?
static variables are stored in a special area of the heap called the "permanent generation".
Difference between array and pointers in c plus plus?
A pointer is simply a variable that can store a memory address and has the same purpose in both languages. The only real difference is that C++ pointers can point at objects (instances of a class) and indirectly invoke their methods, whereas pointers in C (which is not object oriented) cannot.
How many values can store a variable at a time?
The number of values a variable can store at a time depends on the data type of the variable. For example, a variable of type int (integer) in many programming languages can store a single integer value at a time. Similarly, a variable of type float (floating-point number) can store a single floating-point value. Other data types like arrays or lists can store multiple values at a time. The capacity of a variable to store values is determined by its data type and memory allocation.

they do not have a stomach to store there food
