3．输入下列源程序，按提示输入相应的数据，写出运行结果，并分析源程序。

#include #include struct Person { char name[31]; int age; char address[101]; struct Person *next; }; struct Person *createLink(); void printLink(struct Person *pt); void distroyLink(struct Person *LinkHead); void main() { struct Person *LinkHead; LinkHead=createLink(); printLink(LinkHead); distroyLink(LinkHead); } struct Person *createLink() { struct Person *LinkHead, *LinkEnd, *pt; int i; printf(\ for(i=0; i<3; i++) { pt= (struct Person *)malloc(sizeof(struct Person)); scanf(\ if(0==i)
