出现异常

}
void original(char *str [],int num)
{
int i;
//char *pt;
for (i = 0; i < num; i++)
{
// pt = str;
puts(str);
}
}
void order_ascii(char *str1[], int num)
{
char *temp;
int top, seek;
int i;
for(top = 0;top<num-1;top++)
for (seek = top + 1; seek < num; seek++)
{
if (strcmp(str1, str1) > 0)
{
temp = str1;
str1 = str1;
str1 = temp;
}
}
for (i = 0; i < num; i++)
puts(str1);
}
为什么我无论选a还是b都会出现异常 main.c:29:34: warning: passing argument 1 of 'original' from incompatible pointer type [-Wincompatible-pointer-types]
original(input,ct);
char input;
char *str []
这是两个完全不同的类型
第一个问题，先解决上个问题，这个a就能知道为什么了。
