关于斐波那数列的在不同编译器的问题

Question

为什么我用vs和VC6.0运行这段代码都是错误的呢。在手机的c4droid上运行结果是正确的，请问大神这个差别在哪
#include
int Fibonacci(int k, int m)
{
int i, j,sum;
if (k < 0 || m < 0)
return 0;
int f[1000];
if (m < k - 1) return 0;
else if (m == k - 1) return 1;
else
{
for (i = 0; i < k - 1; i++) f[i] = 0;
f[k - 1] = 1;
for (i = k; i <= m;i++)
{
sum = 0;
for (j = i-k; j <= i; j++)
sum += f[j];
f[i] = sum;
}
}
return f[m];

}
void main()
{
int a, b,c;
printf("请输入k和m的值：\n");
scanf("%d %d",&a,&b);
printf("斐波那契数列的m项值为：\n");
printf("%d", Fibonacci(a, b));
}

Answer 1

 long int fibo(long int a) 
{ 
    if(a <= 2) 
    {
        return 1; 
    }
    else 
    {
        return fibo(a - 1) + fibo(a - 2);
    }
}
