C语言，编写一个简单的通讯录管理系统？？

struct Txl
{
char name[10];
char address[30];
int ems;
int tel;
struct Txl *next;
};
struct Txl *findTxl(struct Txl * head,char name) //查找
{
struct Txl *q,*p;
if(head == NULL)
printf("找不到该该用户!\n");
else if(head->name == name)
{
printf("姓名:%s\n",head->name);
printf("地址：:%s\n",head->address);
printf("邮编:%d\n",head->ems);
printf("联系电话:%d\n",head->tel);
head = head->next;
}
else
{
p = head;
while( (p->name != name) && (p->next != NULL) ) //若都成立，则p到最后一个结点,若不成立，则找到p结点
{
q = p;
p = p->next;
}
if(p->name != name)
printf("找不到该用户!\n");
else
{
printf("姓名:%s\n",head->name);
printf("地址：:%s\n",head->address);
printf("邮编:%d\n",head->ems);
printf("联系电话:%d\n",head->tel);
head = head->next;
}
}
return (head);
}
int main(void)
{
int j=1;
char name1[20];
struct Txl*fristTxl,*p;
while(j>0)
{
printf("--------------------------------\n");
printf("1.输入用户信息\n");
printf("2.查找用户\n");
printf("3.列表用户信息\n");
scanf("%d",&j);
if(j==1)
fristTxl = create();
else if(j==2)
{
printf("所查找的用户姓名:");
scanf("%s",&name1);
fristTxl= findTxl(fristTxl,name1);
}
其余略求大神指点怎么查找？？？

C语言是一门通用计算机编程语言，应用广泛。C语言的设计目标是提供一种能以简易的方式编译、处理低级存储器、产生少量的机器码以及不需要任何运行环境支持便能运行的编程语言。

尽管C语言提供了许多低级处理的功能，但仍然保持着良好跨平台的特性，以一个标准规格写出的C语言程序可在许多电脑平台上进行编译，甚至包含一些嵌入式处理器（单片机或称MCU）以及超级电脑等作业平台。
