[情報] BenQ考題

[hippopus (我有你真好)]

這是上週去BenQ面試時 考的題目
這是手機軟體部門(台北)
給大家參考一下

(三十分鐘作答)Programming 跟 OS
各十題(不過我只記得這些),
他要你各抽四題出來寫
在面試的時候 會看這份考卷


Programing

1. Global static & local static variable

2. Endian
struct p1
{
        short a;
        short b;
};

void func1(long * ptr)
{
        *ptr = 0x12345678;
}

int main()
{
        p1 a;
        func1((long *)&a);
}

With little endian (PC)
a = ?
b = ?

3. Correct following code

char * str1 = "1234";
char str2[10] = "123456";
char * str3;

int main()
{
        str2 = str1;
        str3 = str2;
}


4. implement
void * memmove(void * dest, const void * src, size_t n)
Note that src & dest can overlap

5. Correct following statement
char * strappend(char c)
{
        char str[10] = "abcd";
        int len;
        len = strlen(str);
        str[len] = c;

        return str;
}

OS

1. Internal memory fragmentation & external
2. Race condition & solution
3. Preemptive
4. List IPC's method
5. Software engineering
