C Program to read and print employee details using structure

In this tutorial, we will learn how to write a C program to read and print employee details using structures.

C Program for employee details using structure

#include <stdio.h>

// Define the structure for employee details
struct Employee {
    int id;            // Employee ID
    char name[50];     // Employee Name
    float salary;      // Employee Salary
};

int main() {
    // Declare a variable of type struct Employee
    struct Employee emp;

    // Prompt the user to enter the employee's ID and store it in emp.id
    printf("Enter Employee ID: ");
    scanf("%d", &emp.id);

    // Prompt the user to enter the employee's name and store it in emp.name
    // Note: %s reads a string until a space or newline is encountered
    printf("Enter Employee Name: ");
    scanf("%s", emp.name);

    // Prompt the user to enter the employee's salary and store it in emp.salary
    printf("Enter Employee Salary: ");
    scanf("%f", &emp.salary);

    // Display the employee's details
    printf("\nEmployee Details:\n");

    // Print the employee's ID
    printf("ID: %d\n", emp.id);

    // Print the employee's name
    printf("Name: %s\n", emp.name);

    // Print the employee's salary
    printf("Salary: %.2f\n", emp.salary);

    // Indicate that the program ended successfully
    return 0;
}

How this program works?

1. Include Header File:

   #include <stdio.h>
   

   This line includes the standard input-output library in our C program, which is required for using printf() and scanf() functions.
2. Structure Definition:

   struct Employee {
       int id;
       char name[50];
       float salary;
   };
   

   This defines a structure named Employee which contains three fields: an integer id, a character array name (to hold the employee’s name), and a float salary. This is to store the employee details so that we can later fetch the details from it and print it.
3. Main Function:

   int main() {
       struct Employee emp;
   

   This declares a variable emp of type struct Employee. This variable emp refers to the structure so we can use it to access structure for reading and writing data into it.
4. Taking Input:

   printf("Enter Employee ID: ");
   scanf("%d", &emp.id);
   
   printf("Enter Employee Name: ");
   scanf("%s", emp.name);
   
   printf("Enter Employee Salary: ");
   scanf("%f", &emp.salary);
   

   Here printf statements are prompts to the users asking for input and scanf statements store the user input into the structure using emp.
5. Displaying Details:

   printf("\nEmployee Details:\n");
   printf("ID: %d\n", emp.id);
   printf("Name: %s\n", emp.name);
   printf("Salary: %.2f\n", emp.salary);
   

   These lines print the employee’s details stored in the structure using emp variable.
