Starting To Program With C

[zb0S216C]

#include <stdio.h>
#include <memory.h>

struct f
{
    int *K;
};

void f_Constructor( int Init, f *This ) // Error here.
{
    if( This == NULL )
    {
        // Failed.
        return;
    }

    if( This -> K != NULL )
    {
        // Build the member.
        This -> K = ( int * )malloc( sizeof( int ) );
    }

    // Finished.
    return;
}

void f_Destructor( f *This )
{
    if( This == NULL )
    {
        // Failed.
        return;
    }

    if( This -> K != NULL )
    {
        // Delete the memory.
        free( This -> K );
        This -> K = NULL;
    }
}

int main( )
{
    printf( "This is my first solid C program.\n" );
    return 0;
}

Errors

expected deceleration specifiers or '...' before 'f'

Any ideas what this error means? Bare in mind that I haven't been programming in C for no more than 2 hours.

In C you need to write "struct f".

It worked :) Thanks, Zhuge.
