Harvard CS50: What I Learned and Why Every Dev Should Take It

CS50 feels like drinking from a firehose, but in the best way possible.

C and Memory

Starting with C in 2026 feels archaic to some, but learning to manually allocate memory (malloc), working with pointers, and understanding how data structures look under the hood makes high-level languages feel like magic.

#include <stdio.h>
#include <stdlib.h>

int main(void) {
    int *ptr = malloc(sizeof(int));
    if (ptr == NULL) return 1;
    *ptr = 42;
    printf("%i\n", *ptr);
    free(ptr);
}

Highly recommended for anyone looking to bridge the gap between being a "framework user" and a real software engineer.
