Question

Programming C.......
function code is clear but compile is wrong .. I input 8 and compiled 2 0 1 1 2 3 5 8 13.. look first number 2 is wrong. The correct answer 8 is 0 1 1 2 3 5 8 13 21..
Need fix code to compile correctly..
Here code.c
---------------------------------------------------------------------------------------------------------------------

#include <stdio.h>
#include <math.h>

int fibonacciIterative( int n )
{
        int fib[1000];
        int i;
        fib[ 0 ] = 0;
        fib[ 1 ] = 1;
        

        for ( i = 2; i < n; i++ )
        {
                fib[ i ] = fib[ i - 1 ] + fib[ i - 2 ];
                
        }
        return fib[ n-1 ];
}

void main ( int argc, char * argv[ ] )
{
        int n;
        int i;

        printf("Enter number: ");
        scanf("%d", &n);
        printf("Fibonacci Iteratiion is \n");
        for ( i = 0; i < n; i++ )
        {
                printf("%d: %d\n", i, fibonacciIterative( i ));
        }
        printf("Press key any continue...\n");

}

#include <stdio.h>
#include <math.h>

int fibonacciIterative( int n )
{
        int fib[1000];
        int i;
        fib[ 0 ] = 0;
        fib[ 1 ] = 1;
        

        for ( i = 2; i <= n; i++ )
        {
                fib[ i ] = fib[ i - 1 ] + fib[ i - 2 ];
                
        }
        return fib[ n ];
}

void main ( int argc, char * argv[ ] )
{
        int n;
        int i;

        printf("Enter number: ");
        scanf("%d", &n);
        printf("Fibonacci Iteratiion is \n");
        for ( i = 0; i <= n; i++ )
        {
                printf("%d: %d\n", i, fibonacciIterative( i ));
        }
        printf("Press key any continue...\n");
