What is the size of integer and character pointer?

Consider a compiler where int takes 4 bytes, char takes 1 byte and pointer takes 4 bytes.

What is pointer to a character?

A pointer may be a special memory location that’s capable of holding the address of another memory cell. So a personality pointer may be a pointer that will point to any location holding character only. Character array is employed to store characters in Contiguous Memory Location.

Is a pointer an integer in C?

In this context, you could say that pointers are just integers. However, pointers in C/C++ has always been defined as black box data types. You’re not supposed to use them as integers since they could very well not have what you would call a “numerical value” context that makes sense.

What is the difference between pointer variable and pointer?

a pointer is nothing more than an address, and a pointer variable is just a variable that can store an address. To gain access to the object that a pointer points to, we use the * (indirection) operator. If p is a pointer then *p represents the object to which p currently points.

What is size of character pointer in C?

The size of pointer 1 is 8 bytes and pointer 2 is 8 bytes. Pointer to an Array. An array is a contiguous memory block storing data of the same type.

What is size of int * in C?

The size of an Integer Variable depends upon the type of compiler: if you have a 16 bit compiler: size of int is 2 bytes char holds 1 byte float occupies 4 bytes. if you have a 32 bit compiler: size of each variable is just double of its size in a 16 bit compiler int hold 4 bytes char holds 2 bytes float holds 8 bytes.

What do you mean by character pointer in C?

A pointer is a special memory location that is capable of holding address of some other memory cell. So a character pointer is a pointer that can point to any location holding character only. Since the content of any pointer is an address, size of all types of pointer ( character, int, float , double) is 4.

Is a pointer always int?

Nothing is always safe; of course a pointer isn’t just an integer but it is always representable as an integer (it might be an int or a long or even a 30-bit value but you could declare that is an integer ).

What is the difference between variable and pointer in C?

Ordinary variables hold values of their type while pointers always hold addresses. Notice that pointer variable holds address; address of some variable or pointer variable while ordinary variables hold values of their respective types.

What is the difference between character pointer and integer pointer explain with an example?

Type char is a byte wide type. This means, it can store 8 bits of information. So type char can store numbers from -127 to 126. Type int is a 4-byte wide type, so it can store 32 bits of information.
