发帖数: 8976 | 5 1, !! is to concatenate character variables
"a"!!"b"="ab"
lenght of City_Country should be
length of First + lenght of " ," (1) + length of "England"
length 是在 compile 的时候决定的,compile的时候Function不执行
2, default length of the scan function result is 200
3, 原题的delimiter可能是', '即逗号和空格,你仔细看看
1，
data test;
first='Ipswich, England';
City_Country= Substr(First, 1,7)!! ','!!'England';

请问这个！！(两个感叹号）是什么意思啊，是空格吗？好像在online tutor中没见过。
还有为什么length of city_country 是25？为什么不是17呢？
substr出来的值有default长度的吗？

发帖数: 1145 | 8 Already found a bug in your code.
--> int length=sizeof(input)/sizeof(int);
This will always set lenght as 1. Because input is an int* pointer that's
passed into the function, therefore sizeof(input) = sizeof(int*) = 4. |

actually, we will traverse all the posting list at most once,
so it's O(n)
like this:
record all the occurrence positions in the longer array in the following
posting list
a[0]: 1 5 7 8 13 19
a[1]: 2 9 20
a[2]: 13 15 17
...
keep a cursor in each posting list.
firstly locate the 1st ordered positions
then move the a[0] cursor forward and check if there is need to update.
the number of updates is at most sum of all posting lists lenghts
the number of checks is complicated, but seems also O(n) |

我现在有CITI的CC，有两年了吧。然后一张AMEX的BLUE什么，今年5月申请的。再上一
次申请的应该是08年的事情了，当时被WAMU拒绝了。
他们拒绝我理由是：
Insufficient lenght of credit history
Presence of a resent inquiry
High percentage of credit profile consists of credit cards
来自EXPERIAN
第一个我觉得说服力不够
第二个，我前面说了，这两年就上次的WAMU和5月的AMEX了。可能5月离现在太近了？
第三个不是很明白什么意思，欠信用卡公司钱比例太高？我AMEX的还请很久了。CITI估

[1] Phase I:
Banks withhold foreclosure properties, control short sale prices.
Supply: non-foreclosed properties.
Median sale price goes down about 10% a year.
Last 2 -3 years
[2] Phase II:
Banks withhold most foreclosure properties listed at $300,000 or higher;
放出低价房(under $300,000).
[3] Phase III:
银行放出高价房.
During phase II and III, banks control the supply. The lenght of them
depends on the capital market.

下午击了近60个球，打了half round，有点感受。
我没自己仔细check这2套club的lenght, lie， loft等差距，
但就感觉，775cb能比mizuno mx23 hit longer.
我不喜欢mizuno mx23的原因就是因为club face太大了，775cb显然好些。
其它讲不出什么了。似乎能喜欢775cb多些。
不过用这套2－3个月后， 我估计我又 要换了。

发帖数: 438 | 40 I'm a bit confused with what you want.
Are you talking about the lenght of your sql command
statement, or the length of the column?
* If it's command statement, you may try put it in a stored
proc.
* If it's the length of the column (assuming you are using a
TEXT field):
If you use VC++'s ODBC, TEXT column is mapped to RFX_TEXT.
And it takes a default nMaxLength of 255 (you can check the
prototype of RFX_TEXT in afxdb.h). Just supply your length
to overwrite the default value. |

发帖数: 6806 | 43 The array size information is bound to the array type. But if the function
you called does not know the type of the array, i.e. doesn't know the lenght
of the array, then you can not know the length of array. :)
That is to say, you have to know the length of array before you know the
length of array. So the answer is no for C language. For C++, this can be
solved with template.
Please read C FAQ, there's a section for array and pointer.
