摩托羅拉通訊筆試題
筆試20題通訊多選，10題計算機多選。
通訊考的都是基礎知識，但是不是通訊專業的一般都要靠摸的，計算機考的比較有深度，主要是c和c++;類的繼承關系(初始化順序);二*樹的先序、中序、后序，知道其中兩個，推導剩下的一個;i++和++i問題。
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面試中英語口語很重要，技術面試一開始就是用英語的'，后來不行了，只好用中文。第二面的那個人力資源的主管就是全英文了，一路面下來不吐一個漢字。二面的時候主要就是聊天了，問問你的愛好，和同學關系什么的，主要是看口語，以及你個人的性格。

//計算字符串長度的函數
int strlen_mod(char* str)
{ int count = 0;
while(str[count] != ‘\0′)
{ ++count;}
return count;
}
//將字符串反轉輸出的函數
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? 輸出結果是?
main()
{ char *p1=“name”;
char *p2;
p2=(char*)malloc(20);
memset (p2, 0, 20); //
while(*p2++ = *p1++);
printf(“%sn”,p2);
}
Answer:empty string.
