各位路过的大哥大姐麻烦帮小弟找找错啊！！
题目是这样的：要求编程输出杨辉三角的前十行
下面是小弟自己编的程序，在TC2.0上编译执行后前面8行都是对的可是后面两行就出错了。望各位大神指点一二，小弟不胜感激。哦，对了那个由于小弟是个新人加菜鸟囊中实在羞涩，这给分少了各位别介啊！
#include<stdio.h>
int main()
{
int a[10][10]={1};
int n,m;
int combition(int x);
printf("\n");
printf("%3d\n",a[0][0]);
for (n=1;n<=9;n++)
{
printf("\n");
for (m=0;m<=n;m++)
{
if (m==0)
a[n][m]=1;
a[n][m]=combition(n)/(combition(n-m)*combition(m));
printf("%3d ",a[n][m]);
}
}
return 0;
}
int combition(int x)
{
int i,z;
z=1;
for (i=1;i<=x;i++)
z=z*i;
return(z);
}

我觉得作为一个杨辉三角，还是用+来做的好。你用乘容易导致数据丢失。

C/C++ code

#include<stdio.h>int main(){    int a[10][10]={1};    int n,m;    int combition(int x);    printf("\n");    printf("%3d\n",a[0][0]);    for (n=1;n<=9;n++)    {        for (m=0;m<=n;m++)        {            if (m==0||m==n)                a[n][m]=1;            else            {                a[n][m] = a[n-1][m-1] + a[n-1][m];            }        //    a[n][m]=combition(n)/(combition(n-m)*combition(m));            printf("%3d ",a[n][m]);        }        printf("\n");    }    return 0;}

TC 2.0是16位编译器，应该是整数溢出了吧，将所有的int改为long试一试。
