本来我单独写下面一段没错，后来又新做了一题写了
        struct abc
        {
                char name[20];
                int age;
        }*s,*s1;
        int j;
        s=new struct abc[k];
        if(s==NULL) abort();
        s1=s;
        cout<<"*s=\n";
        for(j=0;j<=k-1;j++)
        {
                cin>>s->name>>s->age;
                cout<<s->name<<" "<<s->age<<"\n";
                s++;
        }
    delete s1;
这一段，好像这段和后面的没有什么影响 ，可是为什么下面那段的程序受到影响出错了呢？
