笔试20题通讯多选，10题计算机多选。

通讯考的都是基础知识，但是不是通讯专业的一般都要靠摸的，计算机考的比较有深度，主要是c和c++;类的继承关系(初始化顺序);二*树的先序、中序、后序，知道其中两个，推导剩下的一个;i++和++i问题。

例如:

int i=1;

int j;

j=(++i)+(++i)+(++i)+(++i); j=15

int i=1;

int j;

j=(++i)+(++i)+(i++)+(i++)+(++i); j=16

moto面试中英语口语很重要，技术面试一开始就是用英语的，后来不行了，只好用中文。第二面的那个人力资源的主管就是全英文了，一路面下来不吐一个汉字。二面的时候主要就是聊天了，问问你的爱好，和同学关系什么的，主要是看口语，以及你个人的性格。

计算字符串长度的函数

int strlen_mod(char* str)

{ int count = 0;

while(str[count] != \0)

{ ++count;}

return count;

}

将字符串反转输出的函数

void print_reverse(char* str)

{ size_t size = strlen(str);

int size2= strlen_mod(str);

printf(The length of %s is %d ### %d\n, str, size, size2);

int i;

char temp = ;

for(i=0; i size/2; i++)

{ printf(%d\n, i);

temp = str[i];

str[i] = str[size - 1 - i];

str[size - 1 - i]= temp;

}

printf(Reverse string: %s\n, str);

}

What will print out? 输出结果是?

main()

{ char *p1=name;

char *p2;

p2=(char*)malloc(20);

memset (p2, 0, 20);

while(*p2++ = *p1++);

printf(%sn,p2);

}

Answer:empty string.

Answer: 5,20,1

What will be printed as the result of the operation below:

#define swap(a,b) a=a+b;b=a-b;a=a-b;

void main()

{

int x=5, y=10;

swap (x,y);

printf(%d %dn,x,y);

swap2(x,y);
