Lecture 3.2.4 C pointer to Structure.pptx
- 1. DISCOVER . LEARN . EMPOWER Structure: Structure and functions, Structures and pointers INSTITUTE - UIE DEPARTMENT- ACADEMIC UNIT-2 Bachelor of Engineering (Computer Science & Engineering) Subject Name: Introduction to Problem Solving Code:23CSH-101
- 2. Introduction to Problem Solving Course Objectives 2 The course aims to provide exposure to problem- solving through programming. The course aims to raise the programming skills of students via logic building capability. With knowledge of C programming language, students would be able to model real world problems.
- 3. 3 CO Number Course Outcome CO1 Remember the concepts related to fundamentals of C language, draw flowcharts and write algorithm/pseudocode. CO2 Understand the way of execution and debug programs in C language. CO3 Apply various constructs, loops, functions to solve mathematical and scientific problem. CO4 Analyze the dynamic behavior of memory by the use of pointers. CO5 Design and develop modular programs for real world problems using control structure and selection structure. Course Outcomes
- 5. Structure and Pointers • Pointer to structure: Pointer which stores address of structure is called as “Pointer to Structure “. • Explanation : 1. sptr is pointer to structure address. 2. -> and (*). both represents the same. 3. These operators are used to access data member of structure by using structure’s pointer. 5
- 6. • Example: Program to create a structure and display the content using pointer. #include<stdio.h> struct team { char *name; int members; char captain[20]; } t1 = {"India",11,"Dhoni"} , *sptr = &t1; int main() { printf("nTeam : %s",(*sptr).name); printf("nMemebers : %d",sptr->members); printf("nCaptain : %s",(*sptr).captain); return 0; } 6 Output:
- 7. 7 Summary A structure can be passed to any function from main function or from any sub function. Structure definition will be available within the function only. It won’t be available to other functions unless it is passed to those functions by value or by address Else, we have to declare structure variable as global variable. That means, structure variable should be declared outside the main function. So, this structure will be visible to all the functions in a C program. To access members of a structure using pointers, we use the -> operator. We can also initialize the array of structures using the same syntax as that for initializing arrays.
