Can multiple pointers point to same address?

There is no limit on the number of pointers that can hold (and therefore point to) the same address.

Can you assign a pointer to a variable?

We may think of setting a pointer variable to point to another variable as a two-step process: first we generate a pointer to that other variable, then we assign this new pointer to the pointer variable.

Is correct way to declare pointer variable?

Explanation: int *ptr is the correct way to declare a pointer.

Can two pointers have the same name?

2 Answers. Variables are local to the scope they are defined, so no this should not be a problem at all. Your code only incidentally references the same variable. If the variable had been declared in the global scope (outside of any function) then you might have a problem.

Is it possible to add pointers to each other?

Pointers contain addresses. Adding two addresses makes no sense because there is no idea what it would point to. Subtracting two addresses lets you compute the offset between the two addresses. An array name acts like a pointer constant.

How do you turn a pointer into a variable?

Pointers are said to “point to” the variable whose address they store. An interesting property of pointers is that they can be used to access the variable they point to directly. This is done by preceding the pointer name with the dereference operator ( * ). The operator itself can be read as “value pointed to by”.

How do I declare multiple pointers?

and a single statement can declare multiple variables of the same type by simply providing a comma-separated list ( ptr_a, ptr_b ), then you can declare multiple int-pointer variables by simply giving the int-pointer type (int *) followed by a comma-separated list of names to use for the variables ( ptr_a, ptr_b ).

Can a pointer and variable have same name?

the question: can the code have a variable and a pointer with the same name? If they were each local to different functions (or different files) then they are in different ‘scopes’ then, YES then can have the same name. What you have is a variable names pointer whose type is int * , i.e. a pointer to an int .
