To develop a C program that fulfills the specified requirements, including declaring a calendar as an array of 7 elements, dynamically allocating memory for strings, and implementing the create(), read(), and display() functions, you can use the following code:
#include <stdio.h>
#include <stdlib.h>
#define MALLOC(p,n,type)
{
p=(type*)malloc(n*sizeof(type));
if(p==NULL)
{
printf("Insufficient Memory\n");
exit(0);
}
}
typedef struct{ char *dayName; char *date; char *activity; }Day;
void create(Day *calendar) { int i; for (i = 0; i < 7; i++) { MALLOC(calendar[i].dayName,20,char); MALLOC(calendar[i].date,20,char); MALLOC(calendar[i].activity,100,char); } }
void read(Day *calendar) { int i; for (i = 0; i < 7; i++) { printf("Enter the name of the day for day %d: ", i + 1); scanf("%s", calendar[i].dayName);
printf("Enter the date for day %d: ", i + 1);
scanf("%s", calendar[i].date);
printf("Enter the activity description for day %d: ", i + 1);
scanf(" %[^\n]s", calendar[i].activity);
}
}
void display(Day *calendar) { int i; printf("Weekly Activity Report:\n"); for (i = 0; i < 7; i++) { printf("Day %d:\n", i + 1); printf("Day Name: %s\n", calendar[i].dayName); printf("Date: %s\n", calendar[i].date); printf("Activity: %s\n", calendar[i].activity); printf("\n"); } }
int main() { Day *calendar; int i; MALLOC(calendar,7,Day); create(calendar); read(calendar); display(calendar); for (i = 0; i < 7; i++) { free(calendar[i].dayName); free(calendar[i].activity); } return 0; }
