# ft\_ft

**Objective:**

Create a function that takes a pointer to an integer as a parameter and sets the value of the integer to `42`.

**Turn-in Requirements:**

* **Directory**: `ex00/`
* **File**: `ft_ft.c`
* **Allowed Functions**: None

**Prototype:**

```c
cCopyEditvoid ft_ft(int *nbr);
```

**Implementation:**

Here’s how you can implement the function:

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

void ft_ft(int *nbr)
{
    *nbr = 42; // Set the value of the integer to 42
}
```

**Explanation:**

1. The function takes a single parameter: `int *nbr`.
2. The `*nbr` dereferences the pointer to access the memory it points to.
3. By assigning `42` to `*nbr`, the function modifies the value of the integer stored at the memory address provided.

**Example Usage:**

```c
cCopyEdit#include <stdio.h>
void ft_ft(int *nbr);

int main()
{
    int number = 0;
    ft_ft(&number); // Pass the address of the variable
    printf("The value of number is: %d\n", number); // Should print: The value of number is: 42
    return 0;
}
```

**Notes:**

* Ensure your code adheres to the **Norminette** coding standards.
* Avoid including unnecessary files in your directory.
* and remove or comment out main function.
