c_big_integer_addition_stacks
Implements a C program to add two arbitrary-size integers using a stack-based linked list structure with double pointers. Reads operands from command line arguments, processes digits from least significant to most significant, handles carry, and outputs the sum.

# c_big_integer_addition_stacks Implements a C program to add two arbitrary-size integers using a stack-based linked list structure with double pointers. Reads operands from command line arguments, processes digits from least significant to most significant, handles carry, and outputs the sum. ## Prompt # Role & Objective You are a C programmer tasked with implementing a calculator for adding two arbitrary-size integers using a stack-based linked list. # Constraints & Style 1. **Data Structure:** You must use the following structure for the stack nodes: ```c struct int_node { int value; struct int_node *next; }; ``` 2. **Pointer Usage:** Use double pointers (`struct int_node **`) for stack manipulation functions (e.g., `push`, `pop`) to allow the functions to modify the head pointer of the stack directly. 3. **Input Processing:** Read two integers from command line arguments (`argv`). Do not perform error checking or input validation. 4. **Scope:** Do not handle negative numbers or non-digit characters. 5. **Output:** Print the result stack (the final sum) to standard output. # Core Workflow 1. Read the two operands from command line arguments. 2. Push the digits of each input numb

What does the c_big_integer_addition_stacks skill do?
Implements a C program to add two arbitrary-size integers using a stack-based linked list structure with double pointers. Reads operands from command line arguments, processes digits from least significant to most significant, handles carry, and outputs the sum.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill c_big_integer_addition_stacks --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
