My first year of studying mechatronics engineering in 4 pictures.

@ilepirox @mosaicintel_lab @alimackanic Congratulations ! Things I love to see 🏥🤖

[Emeka @EmekaBuilds_]

@techsis_1813 hmm neetcode

[Emeka @EmekaBuilds_]

The question The solution

[Emeka @EmekaBuilds_]

@_MusiCricket @VazeKshitij How do I get good at embedded DSA please ?

[Emeka @EmekaBuilds_]

Well, I used ternary operators for a LeetCode problem.

[Emeka @EmekaBuilds_]

Same result, different approach.

Ternary operators vs. if-else statements in C.

[Emeka @EmekaBuilds_]

@heyiamthemorgue @SyntaxError2505 Ternaries are for assigning values, not managing control flow. Putting multiple statements into them is a quick way to hit precedence errors and sequence point bugs.

if/else⁠ gives you clean, clear execution order.

[Emeka @EmekaBuilds_]

@justakris_ do-while, can be very useful though.

[Emeka @EmekaBuilds_]

@SyntaxError2505 Yeah, it’s safer, especially if you have more than one line of code to run for each condition.

@zecpplus 😂😂

[Emeka @EmekaBuilds_]

@Ifwal95 @ekom_etuk How can one make it faster? I heard the delay period is usually very long.

[Emeka @EmekaBuilds_]

@ChShersh @tsoding wonders do happen 😂😂

[Emeka @EmekaBuilds_]

Please, I need recommendations for authors to follow on Medium. People who post about robotics, firmware, embedded systems and Linux.

Thanks 🙏

@Dark_Goldenrod Typing "123 456" gives two numbers, since scanf reads 123 and then 456 on the next loop. "abc" prints "Invalid input" and ends the program.

You're right that scanf is fragile. I'll check out fgets and strtoll for safer input handling.

[Emeka @EmekaBuilds_]

I wrote a C program that finds the average of any number of inputs. It uses dynamic memory allocation (calloc and realloc) so the amount of data isn't limited.

[Emeka @EmekaBuilds_]

@ali23985924 okay, thanks 🙏

[Emeka @EmekaBuilds_]

@AnthonyJClink Okay 😂😂😂

[Emeka @EmekaBuilds_]

@AnthonyJClink -1 is the quit value. It ends the program and prints the average of the numbers entered before it. I chose it because averages usually involve zero or positive numbers.

If you need negative numbers, you can change the quit value to something else.

[Emeka @EmekaBuilds_]

@lesbomorphism oh, I’m glad :)

[Emeka @EmekaBuilds_]

@keeyplay I hope so 🥲

@japaneseremedy Thanks :)
