C program for pointer to structure

Basics Of Digital Components. Types of Computer Networks. Classical Synchronization Problem. What are Semaphores? Like we have array of integers, array of pointers etc, we can also have array of structure variables. And to use the array of structure variables efficiently, we use pointers of structure type. We can also have pointer to a single structure variable, but it is mostly used when we are dealing with array of structure variables.

To access members of structure using the structure variable, we used the dot. Learn CSS. Learn JavaScript. C Language C Tutorial. C Compiler. Standard Template Library. Python Python Tutorial.

For example, suppose we want to create the records of a person containing name, age, id, city, etc. Therefore, we use the Structure to store multiple collections of data items. And the last, str, is a variable of the Structure.

In this program creates a student structure and access its member using structure variable and dot. The student structure also defines two variables like s1 and s2 , that access the structure members using dot operator inside the main function.

The structure pointer points to the address of a memory block where the Structure is being stored. Like a pointer that tells the address of another variable of any data type int, char, float in memory. And here, we use a structure pointer which tells the address of a structure in memory by pointing pointer variable ptr to the structure variable. The declaration of a structure pointer is similar to the declaration of the structure variable. So, we can declare the structure pointer and variable inside and outside of the main function.

Let's consider an example to create a Subject structure and access its members using a structure pointer that points to the address of the Subject variable in C.

The structure Employee is having the name, id, age, gender, and city as the member. All the Employee structure members take their respective values from the user one by one using the pointer variable and arrow operator that determine their space in memory.
