Today I found out about a function that I thought would now exit in the C standard library.

Basically I wanted something that would check if a string is a valid double and went and made something with a loop that works if u give it the right input if uk what am saying 🤯. Well that kinda did not set well with me so I made a quick search on gpt and BAM we got something that is in the standard lib that will work.

The function in question is strtod. What it does is simple, it just converts an array of chars to a double. Might look not impressive for most but for a guy that thought, "low level programming, HARD. low level programming has nothing 🐵", this was quite a surprise.

I can't tell u how it converts it under the hood just yet but what I can tell u is how this helped me to check if a string is a valid double or not. So this is the function signature double strtod(const char *str, char **str_end);, well str is the input string and str_end is a pointer to a pointer that stores the address of the first char in the string that was not converted.

So now by checking what the str_end is pointing to, we can check if a string is a valid double or now🤪.

Also am am very alive.👍

Can never forget the day that our Unix Lab instructor told us to execute touch girl command, and went on a rant on how doing an SA is bad for society🐈
