c语言两个字符串数组的连接 通过地址搞定

#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
void link(char *s,char *t)
{
while (*s != '\0')
{
s++;
}
while (*t != '\0')
{
*s++ = *t++;
}
*s = '\0';
}
int main()
{
char p[128] = "123";
char *q = "456";
link(p, q);
printf("连接后的p:%s", p);
system("pasue");
getchar();
return 0;
}
