coding in c until my program is unsafe

C Programming isn't all it's cracked up to be boys and girls.

IT TAKES GUTS. GRIT. DETERMINATION. SELF HATE. LUST?

🔥 SOCIALS 🔥

[Requiem]

just saying "C" and "strings" in one sentence is enough to make me sweat

[OrangeC]

"Read a string from the user"
"Make the code completely safe"
Ah yes, a classic impossible task

[vufmvbn]

"there's gonna be 3 characters so gonna create 3 rooms for it"
null terminator: bonjor

C assignment: "Read a string from the user"

Me, shouting at the screen: "IT'S A TRAP"

[ariss]

real c programmer:

There’s gonna be a string of length 5. I’m going to allocate 2000 bytes on the stack for this

[the_brutal_king]

Why the program was not safe:
1. He did not check if argc was equal to 0, 1, or any other number.
2. He did not terminate the program when outside of parameters e.g. if argc > 2, exit program.
3. He used strcpy, which is considered unsafe as it may be used in buffer overflow attacks. Use strncpy instead.
Probably missed something.

Don't forget to reference your dereference in the pointer to a pointer to determine the number of bits per byte in a parallel universe where we are glad that we have pass by reference.

The moment you said “strings” is when I started laughing hysterically.

Programming in C is like holding a gun, except that it's legal in England.

[civetbutlemonbutmouse]

"Take a string from the user"
*proceeds to NOT include <string.h>*

[gabethedog]

funny watching him walk into a textbook buffer overflow attack

[petros_adamopoulos]

This program wasn't unsafe at this point, because without a semicolon it could not be compiled.

[tenv]

FYI: Nothing wrong with just looking at argv directly, you're only reading it after all so copying it to a buffer on the stack is a waste (and more ways your program can go wrong).

[ImXyper]

"there is a string"
"i should make a buffer 63352482 times larger than the string just in case"

[thanguy]

the most terrifying thing I ever did in a computer science course was to feed a C program unsafe strings to execute arbitrary code. wild shit

[calle]

The most unsafe thing in this video is that monitor placement

[AFvids]

Im grateful that people out there have coded things in c, that we web developers take for granted..
Thank you C lords

[ultimateloser]

C is that one friend you once had great memories with but you're happy not being with now

[Fortexik]

C programmers never die they just cast into void
