Write a C program that creates the dynamically alocated list holding strings with different size. Problem 1: To warm up, declare a double pointer to char variable and set it to NULL. Then, declare an integer el Nr that holds the number of element in the list and set it to 3. Using malloc function allocate a memory block your list to hold 3 items. Now, you need to add the first item (a string) to the list. Check the length of the string you want to add, and allocte a memory block to hold this string, using the malloc function. Remember, to include the space for the end-of-line character. Copy your string to the allocated memory block using strcpy function. Perform the same steps to add two more items. Problem 2: Create a function print_list which prints all elements in the list. Problem 3: Now, you will add automatically the elements to your list. Declare an integer el Nr that holds the number of element in the list, and initiate it with 0. Using malloc function allocate a memory block your list to hold a single item. Create a function add item which adds a new string, passed as an argument, to your list. This function should increase el Nr by one, each time it is invoked, and reallocate the memory block for your list with a new size, using realloc function. Then, allocate the memory block for the string you want to add (the last element of the expanded list), using malloc function. Finally, copy the string you want to add to the allocated memory block, using strcpy function.

Question
Write a C program that creates a dynamically allocated list holding strings with different sizes.
Transcribed Image Text:Write a C program that creates the dynamically alocated list holding strings with different size.
Problem 1:
To warm up, declare a double pointer to char variable and set it to NULL. Then, declare an integer
el Nr that holds the number of element in the list and set it to 3. Using malloc function allocate a
memory block your
list to hold 3 items. Now, you need to add the first item (a string) to the list.
Check the length of the string you want to add, and allocte a memory block to hold this string,
using the malloc function. Remember, to include the space for the end-of-line character. Copy
your string to the allocated memory block using strcpy function. Perform the same steps to add
two more items.
Problem 2:
Create a function print_list which prints all elements in the list.
Problem 3:
Now, you will add automatically the elements to your list. Declare an integer el Nr that holds the
number of element in the list, and initiate it with 0. Using malloc function allocate a memory
block your list to hold a single item. Create a function add_item which adds a new string, passed as
an argument, to your list. This function should increase el Nr by one, each time it is invoked, and
reallocate the memory block for your list with a new size, using realloc function. Then, allocate
the memory block for the string you want to add (the last element of the expanded list), using
malloc function. Finally, copy the string you want to add to the allocated memory block, using
strcpy function.
Problem 4:
Create a function remove_item which removes a string you pass as an argument. This function
should check, if the string you want to remove is in the list, and if it is so, then record the index
of the item you want to remove. You may assume, that there are no double items. To remove the
item, at first free the memory block occupied by the item. Then, shift all subsequent items by one
to the left (for these items, you assign to each pointer the subsequent pointer). For the pointer of
last item in the list, assign NULL. Then, decrease the el Nr variable and reduce memory block for
the list using realloc function.
Problem 5:
Test your code, adding and removing few items, and print the list. Free all the memory before
finishing the program.
