More singly linked lists

Project done during Full Stack Software Engineering studies at ALX AFRICA SE. It aims to learn about singly linked lists in C language.

Technologies

All of the following files are programs written in C:

Filename	Description
`0-print_listint.c`	Prints all the elements of a `listint_t` list
`1-listint_len.c`	Returns the number of elements in a linked `listint_t` list
`2-add_nodeint.c`	Adds a new node at the beginning of a `listint_t` list
`3-add_nodeint_end.c`	Adds a new node at the end of a `listint_t` list
`4-free_listint.c`	Frees a `listint_t` list
`5-free_listint2.c`	Frees a `listint_t` list
