C Program Using struct personal to Read and Print Employee Data

In C programming, structures are used to group related variables under one name. This blog post will guide you on how to define a structure called struct personal that stores a person’s name, date of joining, and salary — and how to use it to read and print information of 5 people.

What is struct personal?

You can define a structure to hold employee data like this:

struct personal {
    char name[50];
    char dateOfJoining[20];
    float salary;
};

---

Objective

• Define a structure named struct personal
• Members:
  • Name (string)
  • Date of Joining (string)
  • Salary (float)
• Input and store data for 5 persons
• Print the data on the screen

C Program Example

#include <stdio.h>

#define SIZE 5

// Define structure
struct personal {
    char name[50];
    char dateOfJoining[20];
    float salary;
};

int main() {
    struct personal employees[SIZE];

    // Reading data
    for (int i = 0; i < SIZE; i++) {
        printf("\nEnter details for Person %d:\n", i + 1);
        printf("Name: ");
        scanf("%s", employees[i].name);

        printf("Date of Joining (DD-MM-YYYY): ");
        scanf("%s", employees[i].dateOfJoining);

        printf("Salary: ");
        scanf("%f", &employees[i].salary);
    }

    // Printing data
    printf("\n--- Employee Information ---\n");
    for (int i = 0; i < SIZE; i++) {
        printf("\nPerson %d:\n", i + 1);
        printf("Name: %s\n", employees[i].name);
        printf("Date of Joining: %s\n", employees[i].dateOfJoining);
        printf("Salary: %.2f\n", employees[i].salary);
    }

    return 0;
}

Sample Output

Enter details for Person 1:
Name: Ravi
Date of Joining: 01-06-2020
Salary: 35000

...
--- Employee Information ---

Person 1:
Name: Ravi
Date of Joining: 01-06-2020
Salary: 35000.00

Key Concepts Covered

• Using arrays of structures.
• Reading strings and floats using scanf.
• Grouping data for real-world scenarios.

---

Tips

• Use fgets() for full names with spaces instead of scanf("%s", ...).
• For date operations, consider using nested structures or date parsing in advanced programs.

Conclusion

This program is a great example of how to use structures in C to handle multiple records efficiently. By using an array of struct personal, you can manage and display employee information cleanly and effectively.

Understanding structure usage in C is key to building scalable and modular programs.
