怎么用C++编写一个程序，输出结果是一个V形状？

#include <stdio.h>
#define N 5
int main(int argc, char *argv[])
{
    int i,j;
    for (i=0;i<N-1 ;i++ )
    {
        for (j=0;j<=i ;j++ )
        {
            printf(" ");
        }
        printf("*");
        for(j=i;j<=N-i;j++)
        {
            printf(" ");
        }
        if ((i<j)||(N%2!=0))
        {
            printf("*");
        }
        printf("\n");
    }
    return 0;
}
