在c中实现n-ary树

Question

有人可以告诉我n-ary树中的二维数组究竟用于什么？

#include <stdio.h>

int main()
{
    int row = 5;//no. of input lines
            //1st element in each row is node Value, 2nd - no of child, ,>=3rd....=>value of child
    int data[5][6];
    int i,j,k,m;
    for (i=0;i<5;i++)
    {
        printf("\nEnter value of Node:\t");
        for(j=0;j<6;j++)
        {
            if(j==1)
                printf("\nEnter no of child:\t");
            else if(j==2)
                printf("\nEnter Values of child\n(if child not present enter 0 as value):\t");
                scanf("%d",&data[i][j]);
        }   
    }

看起来像你所说的n阵列树是由2d数组表示的。它用作存储数据的下划线数据结构。
