About C Programming Language

C is a general-purpose, procedural computer programming language supporting structured programming, lexical variable scope, and recursion, with a static type system.

About Rust Programming Language

Rust is a multi-paradigm programming language focused on performance and safety, especially safe concurrency. Rust is syntactically similar to C++, but its designers intend it to provide better memory safety while still maintaining performance.

Hello World Example: C vs Rust

Hello World in C

#include <stdio.h>
int main() { printf("Hello, World!\n"); return 0; }

Hello World in Rust

fn main() { println!("Hello, World!"); }

Fibonacci Example: C vs Rust

Fibonacci in C

#include <stdio.h>

void fibonacci(int n) {
    int a = 0, b = 1;
    for (int i = 0; i < n; i++) {
        printf("%d\n", a);
        int temp = a;
        a = b;
        b = temp + b;
    }
}

int main() {
    fibonacci(10);
    return 0;
}

Fibonacci in Rust

fn fibonacci(n: usize) {
    let (mut a, mut b) = (0, 1);
    for _ in 0..n {
        println!("{}", a);
        let temp = a;
        a = b;
        b = temp + b;
    }
}

fn main() {
    fibonacci(10);
}
