Are pointer variables that point to the address of a function?

A pointer is a variable that stores the address of another variable. Unlike other variables that hold values of a certain type, pointer holds the address of a variable. For example, an integer variable holds (or you can say stores) an integer value, however an integer pointer holds the address of a integer variable.

Can a pointer point to a value?

When you create a pointer variable, initially it will have garbage value (let say 300 address location). Hence when you dereference pointer(*300), it would give another garbage value(value at 300 address location) or error (strictly speaking anything may happen depending on your computer).

What value is stored in a pointer?

How do you value a pointer?

Declare a normal variable, assign the value. Declare a pointer variable with the same type as the normal variable. Initialize the pointer variable with the address of normal variable. Access the value of the variable by using asterisk (*) – it is known as dereference operator.

How do you pass a pointer to a function?

Pass-by-pointer means to pass a pointer argument in the calling function to the corresponding formal parameter of the called function. The called function can modify the value of the variable to which the pointer argument points. When you use pass-by-pointer, a copy of the pointer is passed to the function.

What is the correct way to declare and assign a function pointer?

Discussion Forum

Que.	The correct way to declare and assign a function pointer is done by: (Assuming the function to be assigned is “int multi(int, int);”)
b.	int *fn_ptr(int, int) = multi;
c.	int *fn_ptr(int, int) = &multi
d.	none of the mentioned
	Answer:int (*fn_ptr)(int, int) = multi;

Is the value of a pointer the address?

A pointer has the value of a variable’s address, since we have a varaible in memory.
