有如下程序：#include ＜stdio.h＞ #define OLD_PRICE 30 #define NEW_PRICE OLD_PRICE+5 main() { int num=10; printf ("%d,", OLD_PRICE*num); printf ("%d", NEW_PRICE*num); } 则输出结果是（）。

阅读以下函数说明和C语言函数，将应填入(n)处的字句写在对应栏内。

【说明】

编写程序，生成一个新文本文件，它由一个已知文本文件的所有偶数行组成。要求已知文本文件名和新文本文件名均从键盘输入。请填空完善程序。

【C语言程序】

include＜stdio.h＞

"New Price"; "Just Reduced"; "Priced to Sell". Once unheard of, these tags are cropping up ever more often in the property sections of America's newspapers. They denote a shift that is becoming clearer in the national statistics, too: the fizz is going out of the once-bubbly housing market. Compared with last year, inventories of unsold houses are up and the pace of sales is down. Prices have slowed and in some areas have even fallen.

Residential construction now makes up more than 6% of GDP. This suggests that a 10% drop would shave some 0.6 percentage points off economic growth. A bigger question, however, is how slower prices might affect consumer spending. Experts expect that America's house prices will have stopped rising by the end of the year. Mainly because a flat market will put a brake on residential building, this is expected to reduce GDP growth by about 1.5 percentage points. "Just Reduced" might soon be a fitting label for the whole economy.
