编译没错误  运行后出现内存问题 不知道怎么解决 求大神 指点；

上一个程序 写的时候 有错误 从新写了一个：
#include<iostream>
using namespace std;
struct teacher{
char* name;
char* fangxiang;
int cs;
};
void output(struct teacher * th)
{
    cout<<th->name<<":"<<th->fangxiang<<th->cs<<endl;}
int main()
{
    int n,i;
struct teacher * th;
cout<<"please input the number:";
cin>>n;
th=new struct teacher[n];
if(th==NULL)
{
    cout<<"memory creat false!!"<<endl;}
else
{
    (th+i)->name=new char[n];
    (th+i)->fangxiang=new char[n];
    if((th+i)->name==NULL&&(th+i)->fangxiang==NULL)
{
    cout<<"memory creat false!"<<endl;}
}
for(i=0;i<n;i++)
{
    cout<<"please input the data"<<endl;
    cin>>(th+i)->name;
    cin>>(th+i)->fangxiang;
    cin>>(th+i)->cs;
}
for(i=0;i<n;i++)
{
    output(th);
}
for(i=0;i<n;i++)
{
    delete[] (th+i)->fangxiang;
    (th+i)->fangxiang=NULL;
    delete[] (th+i)->name;
    (th+i)->name=NULL;   
}
delete[] th;
th=NULL;
return 0;
}

非常感谢 我也知道是内存的非配问题 只是不知道在哪  
内存不够 那不太可能吧
