招聘考题 一
TC2.0 环境下的如下程序, 执行结果为
please input: scanf : floating point formats not linked
Abnormal program termination
试解决
!
#include "stdio.h"
#include "stdlib.h"
main()
{
float *a;
a = (float *)malloc(10*sizeof(float));
printf("
Please input: ");
scanf("%f", &a[0]); /* &a[0] 也不行 */
printf("
What you have input is %f
", *a);
getch();
free(a);
}

招聘考题一道
tc2.0 中用 scanf 输入数组的值不能使用浮点型
只要一用就会出现题目中的错误
据说这是一个没有解决的
BUG
要解决这个问题可以使用一个变量充当 中间人 传送数据
其实方法很多的

Riddles
* Why is a manhole cover round?
* How many cars are there in the USA?
* You've got someone working for you for seven days and a gold bar to pay them. The gold bar is
segmented into seven connected pieces. You must give them a piece of gold at the end of every
day. If you are only allowed to make two breaks in the gold bar, how do you pay your worker?
* One train leaves Los Angeles at 15mph heading for New York. Another train leaves from New
York at 20mph heading for Los Angeles on the same track. If a bird, flying at 25mph, leaves from
Los Angeles at the same time as the train and flies back and forth between the two trains until they
collide, how far will the bird have traveled?
* You have two jars, 50 red marbles and 50 blue marbles. A jar will be picked at random, and then
a marble will be picked from the jar. Placing all of the marbles in the jars, how can you maximize
the chances of a red marble being picked? What are the exact odds of getting a red marble using
your scheme?
* Imagine you are standing in front of a mirror, facing it. Raise your left hand. Raise your right
hand. Look at your reflection. When you raise your left hand your reflection raises what appears to
be his right hand. But when you tilt your head up, your reflection does too, and does not appear to
tilt his/her head down. Why is it that the mirror appears to reverse left and right, but not up and
down?
* You have 4 jars of pills. Each pill is a certain weight, except for contaminated pills contained in
one jar, where each pill is weight + 1. How could you tell which jar had the contaminated pills in
just one measurement?
* If you had an infinite supply of water and a 5 quart and 3 quart pail, how would you measure
exactly 4 quarts?
* You have a bucket of jelly beans. Some are red, some are blue, and some green. With your eyes
closed, pick out 2 of a like color. How many do you have to grab to be sure you have 2 of the
same?
* Which way should the key turn in a car door to unlock it?
* If you could remove any of the 50 states, which state would it be and why?
数学篇
1 1000!有几位数
为什么
2
F(n)=1 n>8 n<12
F(n)=2 n<2
F(n)=3 n=6
F(n)=4 n=other
使用+ - * /和 sign(n)函数组合出 F(n)函数
sign(n)=0 n=0
sign(n)=-1 n<0
sign(n)=1 n>0
3
编一个程序求质数的和例如
F(7)=1+3+5+7+11+13+17=58
智力题
