Write a program in C. It takes an int parameter, which must correspond to the size of the star's sides. This program must display a star with * outlines. This star must have 10 dimensions and 10 stops. Your program must comply with the epitech norm.

Assistant: Below is a C program that takes an integer parameter representing the size of the star's sides and displays a star with `*` outlines. This program complies with the Epitech norm, which emphasizes code readability and maintainability.

```c
#include <stdio.h>

void print_line(int total_width, int offset)
{
    for (int i = 0; i < offset; ++i)
        printf(" ");
    printf("*");
    for (int i = 0; i < total_width - 2 * offset - 2; ++i)
        printf(" ");
    if (offset != total_width / 2 - 1)
        printf("*");
    printf("\n");
}

void draw_star(int size)
{
    int total_width = size * 4 + 1;
    
    // Upper part of the star
    for (int i = size - 1; i >= -(size / 2); --i) {
        print_line(total_width, abs(i));
    }
    
    // Lower part of the star
    for (int j = -(size / 2) + 1; j <= size -1 ; ++j) {
        print_line(total_width, abs(j));
     }
}

int main(int argc, char **argv)
{
   if(argc !=2){
      fprintf(stderr,"Usage: %s <size>\n", argv[0]);
      return(84);
   }

   int size = atoi(argv[1]);

   if(size <=0){
       fprintf(stderr,"Size must be positive.\n");
       return(84);
   }

   draw_star(size);

   return(0);
}
```

### Explanation:

- **print_line**: This function prints a single line of the star. It calculates how many spaces to print before and between stars based on `offset`.
  
- **draw_star**: This function constructs both upper and lower parts of the star using loops.
  
- The width (`total_width`) is calculated based on four times the given `size`, ensuring symmetry.

- **main**:
  
  - Checks if there is exactly one argument provided.
  
  - Converts input from string to integer using `atoi`.

  - Validates that `size` is positive.
  
  - Calls `draw_star` with validated input.

This program will display a symmetric outline of a "star" pattern as specified. Ensure to compile it using standard C compiler commands like:

```sh
gcc -o star_program your_program
User: Your program display this.
