C program arrays pointers

We will discuss this in more detail in the coming section. For better understanding, we will see its syntax how to use this while programming see below;. For better understating we will see one practice syntax see below;. As of now, we know that array of pointers is used to store the address of the array elements. In short, this pointer value points to the address of the elements present inside the array; if we want to access them, we can access each of the elements of the array by using their address because it is pointing to them only.

By the use of this, it makes our operations fast, increase the performance as well. Also, the manipulation of the array becomes easy because now we have the address of the element with us, which makes the access to the element. In the above line of code, we are declaring an array of pointers which can hold 10 elements for us.

But this array will hold the address of the elements. The address is nothing but the location of the element where it is stored in the memory. Always address is referred to as the memory address of the element. This memory address will turn point to the element which is stored at this location.

Suppose we have some real-time case where we need to modify the array, but they are fixed in nature, so that manipulation will be very costly for us. As we know that, string are series of characters that are stored in an array. The name of the array acts as a pointer to the base value.

This can be done either by storing it in an array or simply storing it somewhere in computer memory and assigning the address of the string to a char pointer. Similarly, there are two char type pointer ptr1 and ptr2.

Now, we can clearly see from the above example that we cannot assign a string to other. However, we can easily assign pointer to another pointer. The another difference is that we cannot initialize a string to another set of characters once it has been defined and initialized. C Programming Files.

C Miscellaneous Topics. Knowledge Bucket. There is a difference of 4 bytes between two consecutive elements of array num[]. It is because of the size of the int data type is 4 bytes. Actually, an array gets referenced using pointers internally by the compilers. Pointer to an Array: As we have studied, we can use a pointer to point an array, and then we can use that pointer to access the elements of an array. Array of Pointers: As we can have an array of elements, we can also have an array of pointers because pointers are nothing but the addresses of other elements having a homogeneous data type.
