In the video, a man gives a brief history of C, its usefulness and areas of application in 100 seconds. C language was created in 1972 by Dennis Ritchie, who wanted to create a portable machine language. The language was developed for the UNIX operating system, but has since become the basis for most operating systems today, It is also used in tools like Wim and Git. It has evolved into many modern languages such as C++, C#, Java, Python, etc. C code is straight to machine code. It is a high-level language, but it gives you significant access to memory and hardware. It does not collect garbage, we have to take care of memory usage ourselves. When creating a variable a value and an address, and you can refer to the address with a pointer. After we have stopped using the variable, we can use memory space must be freed to avoid memory leaks. We need to install a compiler for the C language, the best known of which is GCC. We can freely add libraries to our program. The program starts at the main part the program starts to crash. In the video we will show you the most basic conventions of the C language like initializing variables, the main function correctly, the process of writing to the screen, how to create text and how pointers work. It also explains the practicalities of memory allocation and deallocation. The language is procedural and does not support object-orientation. You can create more complex data structures using struct. At the end of the video, he demonstrates how to compile and run, asks us to subscribe and like the video, and to comment if we would like similar content. Says goodbye.
