In addition, scheduling systems, event management software, and resource allocation algorithms often rely on accurately identifying weekdays and weekends.

By incorporating a C program to check weekday or weekend, you can enhance the functionality and efficiency of your programs.

Writing a C Program to Check Weekday or Weekend

To write a C program that checks whether a given date is a weekday or a weekend, you can follow the steps outlined below:

Step 1: Include the Necessary Header Files

To begin, you need to include the required header files in your C program. The headers stdio.h, stdlib.h, and stdbool.h are typically necessary for this task.

The stdio.h header provides functions for standard input and output, while stdlib.h is needed for memory allocation and other general-purpose functions.

The stdbool.h header introduces the bool data type for representing boolean values.

#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>

Step 2: Define a Function to Check Weekday or Weekend

Next, you should define a function that accepts the date as input and returns a boolean value indicating whether it is a weekday or a weekend.

Let’s call this function isWeekday.

bool isWeekday(int day, int month, int year) {
    // Your code to check weekday or weekend goes here
}

Step 3: Implement the Logic to Check Weekday or Weekend

Within the isWeekday function, you can implement the logic to check whether the given date is a weekday or a weekend.

One approach is to utilize the tm structure from the time.h header, which provides information about the date and time.

#include <time.h>

bool isWeekday(int day, int month, int year) {
    struct tm date = {0};
    date.tm_mday = day;
    date.tm_mon = month - 1;
    date.tm_year = year - 1900;

    time_t t = mktime(&date);
    struct tm* updated_date = localtime(&t);
    int weekday = updated_date->tm_wday;

    return weekday >= 1 && weekday <= 5;
}

In the above code, we use the mktime function to convert the provided date into a time_t value.

Then, we retrieve the day of the week using the tm_wday field of the tm structure.

If the weekday value is between 1 and 5 (inclusive), the date is considered a weekday. Otherwise, it is a weekend.

Step 4: Test the Program with Example Input

To ensure that your program functions correctly, it is essential to test it with example input.

Here’s an example usage of the isWeekday function:

int main() {
    int day = 19;
    int month = 6;
    int year = 2023;

    if (isWeekday(day, month, year)) {
        printf("The provided date is a weekday.\n");
    } else {
        printf("The provided date is a weekend.\n");
    }

    return 0;
}

When executed, this program will output whether the provided date, in this case, June 19, 2023, is a weekday or a weekend.
