EX NO 1 B

 Write functions create(), read() and display(); to create the calendar, to read the data from the keyboard and to print weeks activity details report on screen.

Key Components:

• struct Activity: Holds a date (as string) and an activity description.

• Functions:

  • create() and read() – Both take input from the user for each day's date and activity. (They are effectively the same in this code.)

  • display() – Shows the stored calendar entries.

• main():

  • Asks the user how many days to store.

  • Prompts for input method (create or read).

  • Displays all entered activities.

PROGRAM:

#include <stdio.h>

#include <stdlib.h>

#include <string.h>

// Structure to represent a day's activity

struct Activity {

char date[11]; // Date in the format "YYYY-MM-DD"

char activity[100]; // Activity description

};

// Function to create a calendar

void create(struct Activity calendar[], int size) {

for (int i = 0; i < size; i++) {

printf("Enter activity details for Day %d (YYYY-MM-DD): ", i + 1);

scanf("%s", calendar[i].date);

printf("Enter activity details for Day %d: ", i + 1);

getchar(); // Consume newline left by previous scanf

fgets(calendar[i].activity, sizeof(calendar[i].activity), stdin);

}

}

// Function to read data from the keyboard

void read(struct Activity calendar[], int size) {

for (int i = 0; i < size; i++) {

printf("Enter activity details for Day %d (YYYY-MM-DD): ", i + 1);

scanf("%s", calendar[i].date);

printf("Enter activity details for Day %d: ", i + 1);

getchar(); // Consume newline left by previous scanf

fgets(calendar[i].activity, sizeof(calendar[i].activity), stdin);

}

}

// Function to display a weekly activity details report

void display(struct Activity calendar[], int size) {

printf("Weekly Activity Details Report:\n");

for (int i = 0; i < size; i++) {

printf("Day %d: Date: %s\n", i + 1, calendar[i].date);

printf("Activity: %s", calendar[i].activity);

}

}

int main() {

int size;

printf("Enter the number of days in the calendar: ");

scanf("%d", &size);

struct Activity calendar[size];

// Create or read data based on your choice

int choice;

printf("Choose an option:\n");

printf("1. Create Calendar\n");

printf("2. Read Calendar\n");

scanf("%d", &choice);

if (choice == 1) {

create(calendar, size);

} else if (choice == 2) {

read(calendar, size);

} else {

printf("Invalid choice\n");

return 1;

}

// Display the weekly activity details report

display(calendar, size);

return 0;

}
