# ft\_div\_mod

**Objective:**

Create a function that divides two integers and stores both the quotient and the remainder in the memory locations provided by pointers.

**Turn-in Requirements:**

* **Directory**: `ex03/`
* **File**: `ft_div_mod.c`
* **Allowed Functions**: None

**Prototype:**

```c
ft_div_mod(int a, int b, int *div, int *mod);
```

**Implementation:**

Here’s how you can implement the function:

```c
// File: ft_div_mod.c
#include <unistd.h> // Optional, not needed for this task but can be standard practice for headers

void ft_div_mod(int a, int b, int *div, int *mod)
{
        *div = a / b; // Store the quotient in *div
        *mod = a % b; // Store the remainder in *mod
}
```

**Explanation:**

1. **Input Parameters**:
   * `a` and `b` are integers representing the dividend and divisor, respectively.
   * `div` is a pointer where the quotient will be stored.
   * `mod` is a pointer where the remainder will be stored.
2. **Division and Modulus**:
   * The function calculates the quotient (`a / b`) and stores it at the memory location pointed to by `div`.
   * Similarly, it calculates the remainder (`a % b`) and stores it at the location pointed to by `mod`.
3. **Error Handling**:
   * The function checks if `b` is not zero before performing the operations to avoid division by zero.

**Example Usage:**

```c
#include <stdio.h>

void ft_div_mod(int a, int b, int *div, int *mod);

int main()
{
    int a = 42;
    int b = 5;
    int quotient, remainder;

    ft_div_mod(a, b, &quotient, &remainder); // Pass addresses of quotient and remainder
    printf("Quotient: %d, Remainder: %d\n", quotient, remainder);

    return 0;
}
```

**Output:**

```yaml
Quotient: 8, Remainder: 2
```

**Notes:**

* If `b` is zero, the function does nothing. You can add additional error handling if required.
* This exercise demonstrates how to use pointers to return multiple values from a function.
