DevC - Linus Torvalds "Nothing better than C"

[video width=”492″ height=”426″ mp4=”https://dwaves.de/wp-content/uploads/2021/08/Linus-Torvalds-Nothing-better-than-C.mp4″\]\[/video\]

what is great about C?

- the simplicity of the compiler that just run’s anywhere
- still THE most resource efficient language
  - with C the user does not have to buy a new computer every 3 years, because of updates slowing down the system so much it become inefficient
- still THE language that can speak best to hardware
- the syntax can be called ugly sometimes, but not as ugly as C++ X-D

everyone understands what this does:

cat boolstd.c
#include 
#include 

int main(void) {
    // set to true
    bool b1 = 1;

    // this is correct, it will print
    if(b1)
    {
        printf("Bool b1 is true \n");
    }

    // set to false
    _Bool b2 = 2;

    // this is false, will not print
    if(b2 == false)
    {
        printf("Bool b2 is false \n");
    }

    // requires 
    bool b3 = true;

    // this is correct, it will print
    if(b3 == true)
    {
        printf("Bool b3 is true \n");
    }

    // requires 
    bool b4 = false;

    if(b4 == false)
    {
        printf("Bool b4 is false \n");
    }
}

the problems of C:

security problems need to be adressed (all those buffer over- and underruns)

… security/safety plus multi core computing is what RUST tries to adress

RUST the safer C/C++?
