C Program to print date of birth using structure

In this guide, we will learn how to write a C program to print date of birth using structure. This program will help you understand the usage of structure.

C Program to print a person’s date of birth using structure

The explanation of this program is provided at the end of the code along with the output.

#include <stdio.h>

// Define a structure to hold a date
struct Date {
    int day;
    int month;
    int year;
};

int main() {
    // Declare a variable dob of type Date
    struct Date dob;

    // Input the date of birth and store in structure
    printf("Enter date of birth (DD/MM/YYYY): ");
    scanf("%d/%d/%d", &dob.day, &dob.month, &dob.year);

    // Print the date of birth
    printf("Date of birth: %02d/%02d/%d\n", dob.day, dob.month, dob.year);

    return 0;
}

Explanation:

1. Structure Definition:
   • We define a structure named Date to hold day, month, and year. This is where we will store the input date, which we can later retrieve it using the dob variable.
2. Main Function:
   • We declare a variable dob of type Date to store the date of birth in the structure Date.
   • The program prompts the user to input the date of birth in the format DD/MM/YYYY.
   • The scanf function reads the input and stores the values in structure Date using dob variable.
3. Output:
   • The program fetches the data from structure Date using dob variable and prints the date of birth using the printf function, formatting the output as DD/MM/YYYY.

Output:

Enter date of birth (DD/MM/YYYY): 15/05/1990
Date of birth: 15/05/1990
