Today I learned how to basically convert an array to a string in the form of a sentence.
Mainly in C, because I already knew how to do it in Python.
The problem is making an array like {"This", "is", "a", "sentence"} into a string like “This is a sentence”.
Here was my first attempt, which is way longer than what I ended up with:
Here is the main function:
And it ouputs: This is a sentence
This works well but it can be simplified to be more writable.
I found someone’s solution, which saved the sentence to a string using sprintf, which is fine because we know our math in calculating the buffer size is correct; however, I wanted to learn how to implement this using snprintf, the more secure version because it includes a buffer size to prevent buffer overflow.
Here’s my version of the code:
Apparently calloc(1, sizeof(1)) is the same as calloc(1, 1), but it’s self-documenting code, which I am trying to get better at.
In this case, my code might be over-documenting, but this is basically my writeup and I’m explaining in depth so it’s easier to understand later if I need to reference this.
This worked.
Here’s the Python implementation:
This prints: `hi there 3rdword"
If anyone is reading this, please let me know if you actually found this helpful, so I know whether to keep these as writeups for myself or detailed explanations.
