Question
The following code has five errors. Identify and correct the errors.

```c
#include <stdio.h>

int main ( void )
{
    int i;
    int N;

    puts("Hello world!")  // Error: Missing semicolon here.

    scanf("%f", N);       // Error: Incorrect format specifier. Should be "%d" for integer N 
                          // and format should pass the address of N using "&".

    for (i = 1; i <= n; i++);  // Error: 'n' should be 'N' (case-sensitive) 
                               // and remove the semicolon at the end of the for statement.

    {
        puts("C is a strict language.");
    }
}
```

Explanation of Errors:

1. **Missing Semicolon:** There is a missing semicolon on the line with `puts("Hello world!")`.

2. **Incorrect Format Specifier:** In the `scanf` function, the format specifier `%f` is incorrect for an integer. It should be `%d`, and the variable should be passed by reference using `&N`.

3. **Incorrect Variable Name:** The `for` loop uses `n` which is undefined. It should be `N`.

4. **Semicolon After For Statement:** There is an unnecessary semicolon after the `for` loop which causes the loop to not execute as expected.

5. **General Code Structure:** The logic within the loop needs proper structuring to ensure the correct execution flow, though this is implied through fixing errors above.
