[...] You can use the free() function to free the memory. Here is an example: int *tab; tab = malloc(10 * sizeof(int)); alloue de la mémoire pour un tableau de 10 entiers Utilisez la mémoire allouée pour stocker des données free(tab); libère la mémoire allouée It is important to note that in this example, the memory is released once you no longer need it. If you don't free the memory, it can lead to memory leaks and performance problems. Basic data structures in arrays, strings, etc : Basic data structures in C include arrays, strings and structures.

[...] This instruction allocates memory for 10 integers, and returns a pointer to the beginning of this allocated memory. Once we have allocated memory, it is important to free that memory once we no longer need it. To do this, we can use the "free" function, which frees the previously allocated memory block. For example, to free the integer array we allocated above, we can write "free(my_array);". It is important to note that not following memory management can lead to memory leaks, which can cause problems such as segmentation errors or program slowdowns. [...]

[...] In sum, the "Introduction to Basic Computer Programming Concepts" portion of CS50: Introduction to Computer Systems Science is a crucial part of the course, providing students with the foundation for practical programming and problem-solving skills. Students learn about data types, operators, control structures, functions, arrays and pointers, as well as advanced concepts such as memory manipulation and data structure design. After learning the basic concepts of computer programming in Part 1 of the course, students in CS50: Introduction to Computer Systems Science are ready to move on to Part which focuses on high-level programming languages such as Python and JavaScript.
