c++使用指针将字符串进行排序，使用自定义的比较函数。。我想知道我哪里除了小错误？

#include
using namespace std;
int main()
{
short strcmp2(char *c1,char *c2);
char *ch[4] = {"Africa","Asia","America","Europe"};
char **p = ch;
char **_end = (ch+3); char **_end_1 = (ch+2);
char **p1;
char **p2;
char *temp;
char **t = p;
for(p1 = p;p1<=_end_1;p1++){
t = p1;
for(p2 = (p1+1);p2<=_end;p2++){
if(strcmp2(*t,*p2)==1) t = p2;
}
temp = *p1; *p1 = *t; *t = temp;
}
for(p1 = p;p1<=_end;p1++){
cout<<*p1< }
return 0;
}
short strcmp2(char *c1,char *c2){
short b = 0;
for(;(*c1 != '\0')&&(*c2 != '\0');c1++,c2++)
{
if(*c1>*c2) b = 1;
else if (*c1<*c2) b = -1;break;
}
return b;
}

现在的输出，没有很好的排序。。我想知道哪里错了。。为什么错了

把函数
short strcmp2(char *c1,char *c2){
short b = 0;
for(;(*c1 != '\0')&&(*c2 != '\0');c1++,c2++){
if(*c1>*c2) b = 1;
else if (*c1<*c2) b = -1;break;
}
return b;
}
改成
short strcmp2(char *c1,char *c2){
short b = 0;
for(;(*c1 != '\0')&&(*c2 != '\0');c1++,c2++){
if(*c1>*c2){
b = 1;
break;
}
else if (*c1<*c2){
b = -1;
break;
}
}
return b;
}
原因你自己对照看吧！可续问。

自定义函数时字符串的格式:char *function(); char *function(char ch[]) { return ch; } main { char c[]={"abcdefg"}; printf("%s",function(c)); }

for(;(*c1 != '\0')&&(*c2 != '\0');c1++,c2++) 这个地方100%报错
