1.本章思维导图：
Example1:
char
*strcpy(char *target, const char *source) {
char *t = target;
// Copy the contents of source into target.
while(*source) *target++ = *source++;
// Null-terminate the
target.
*target = '\0';
// Return pointer to the
start of target.
return t;
}
Example2:
void
*memmove(void *target, const void *source, size_t count)
这个函数即使
是在源和目的字符串有所重叠时操作也能成功，虽然source为const，但是其指向的array也可能被修改。
2.

两种语言编译都可以通过
当执行到
*q = 't';
时，C++程序出现内存访问错误，C程序可� ......
