C Structure Test

Syntax

struct structure_name {
   data_type1 member_name1;
   data_type2 member_name2;
   ...
   data_typeN member_nameN;
};

Example

#include <stdio.h>
#include <string.h>

struct student {
  int roll_no;
  char name[50];
  float percentage;
};

int main() {
  struct student s1;

  s1.roll_no = 1;
  strcpy(s1.name, "John Doe");
  s1.percentage = 86.5;

  printf("Student Roll Number: %d\n", s1.roll_no);
  printf("Student Name: %s\n", s1.name);
  printf("Student Percentage: %.2f\n", s1.percentage);

  return 0;
}

Output

Student Roll Number: 1
Student Name: John Doe
Student Percentage: 86.50

Explanation

In C programming, a structure is a user-defined data type that groups related data of different data types. A structure is similar to a class in object-oriented programming. It has members that can be of different types, including primitive data types such as int, float, and char, as well as other structures.

Use

C structures are useful in a variety of situations, such as:

• Representation of complex data types that require grouping of data of different types.
• Encapsulation of data and functions as a single entity.
• Passing multiple values to functions as a single parameter.
• Creating custom data types that represent higher-level concepts.

Important Points

• Structures are user-defined data types that group related data members of different data types.
• Structures can be accessed using the dot operator (.) to access individual members.
• Structures can be passed to functions as parameters to consolidate data.
• Structures can be used to represent complex data types and encapsulate data and functions as a single entity.

Summary

C structures are user-defined data types that group related data members of different data types. They can be used to represent complex data types, encapsulate data and functions as a single entity, pass multiple values to functions as a single parameter, and create custom data types. Understanding their syntax and use cases can greatly enhance the functionality of your C programs.
