ArrayList C

This is a simple implementation of an ArrayList in C using a struct, a pointer to the struct and a pointer to the array. The array is static and the size of the array is defined when the ArrayList is created.

Functions

• ArrayList* ArrayCreate(int n): Creates an ArrayList with a size of n.

• void ArrayAppendFirst(ArrayList* list, int value): Add an element to the beginning of the list.

• void ArrayAppendLast(ArrayList* list, int value): Appends a value to the end of the array.

• void ArrayAppend(ArrayList* list, int value, int index): Appends a value to the array at the specified index.

• void ArrayDelete(ArrayList* list, int index): Deletes the element at the given index.

• void ArrayDeleteFirst(ArrayList* list): Deletes the first element of the array.

• void ArrayDeleteLast(ArrayList* list): Deletes the last element of the array.

• void ArrayPrint(ArrayList* list): Prints the array

• void ArrayFree(ArrayList* list): Frees the memory

• char* ArrayToString(ArrayList* list): Returns a string representation of the array

Usage

// Create an array list with maximum 10 value capacity.ArrayList*list=ArrayCreate(10);
// Append a value to the last of the array list.ArrayAppendLast(list, 10);
ArrayAppendLast(list, 20);
ArrayAppendLast(list, 30);
ArrayAppendLast(list, 40);
// Append a value to the first of the array list.ArrayAppendFirst(list, 5);
// Append a value to the array list at the specified index.ArrayAppend(list, 25, 2);
// Print the array list.ArrayPrint(list);
// Delete a value from the array list at the specified index.ArrayDelete(list, 3);
// Delete a value from the first of the array list.ArrayDeleteFirst(list);
// Delete a value from the last of the array list.ArrayDeleteLast(list);
// Print the array list.ArrayPrint(list);

And the output is:

5 10 25 20 30 40
10 25 30
