✨ lis_array_sum(3) ✨

okay bestie, welcome to the Lis Library Functions corner of the manual — this one's called lis_array_sum and it's literally the simplest lil glow-up in the whole library 💖

---

🌸 NAME 🌸

lis_array_sum — calculate the sum of the elements of the vector

like... all of them. every single one. added together. that's it, that's the function 🫶

---

🎀 SYNOPSIS 🎀

#include "lis.h"

LIS_INT lis_array_sum(LIS_INT n, LIS_SCALAR x[], LIS_SCALAR *value);

---

💅 DESCRIPTION 💅

Calculate the sum of the elements of vector x. she just... adds. and honestly? iconic. no notes 👑

Here's the one thing she needs from you before she starts:

• n — The size of the vector

---

🌈 INPUT 🌈

• x — The array that stores the vector

---

🦋 OUTPUT 🦋

• value — The sum of the vector elements

so you hand her a vector, she hands you back one singular number that is everybody summed up. main character energy fr fr ✨

---

💜 EXIT STATUS 💜

The following exit values are returned:

• 0 — The process is normally terminated 🎉
• unspecified — An error occurred 😭

no cap, if you get unspecified something went sideways and you're on your own figuring out what. not me being vague, that's genuinely what the page says 💀
