1、專業(yè)好文檔廣播電視大學(xué)c+語言程序設(shè)計期末考試試題2001年元月一、填空（每空2分，共20分）1 c+目標(biāo)程序經(jīng)_連接_后生成擴展名為exe的可執(zhí)行程序文件。2 16位計算機中整型占_2_個字節(jié)存儲空間。3 要在屏幕上顯示hello，world!應(yīng)執(zhí)行語句cout=0|x=0) coutabcd；else coutwxyz；屏幕上顯示的是abcd 。7 設(shè)一維整型數(shù)組data已進行了初始化，則其元素個數(shù)可由操作符sizeof通過表達式sizeof(data/data0)_計算出來。8 若一全局變量只允許本程序文件中的函數(shù)使用，則定義它時應(yīng)加上修飾符_static。9 設(shè)有int w34；，pw

2、是與數(shù)組名w等價的數(shù)組指針，則pw應(yīng)初始化為_ int (* pw)4=w。10.要使引用pr代表變量char * p；，則pr應(yīng)初始化為char * &pr=p。二、單項選擇題（每空2分，共20分）1下列變量名中，（a ）是合法的。a china b byte-size c double d a+a2下列各種函數(shù)中，（c ）不是類的成員函數(shù)。 a 構(gòu)造函數(shù) b 析構(gòu)函數(shù) c 友元函數(shù) d 拷貝構(gòu)造函數(shù)3下列（ a ）是正確的語句。 a ； b a=17 c x+y d coutn4循環(huán)while(int i=0) i-；執(zhí)行次數(shù)是（ a ）。 a 0 b 1 c 5 d 無限5設(shè)int f(

3、int)；和int g(int)；是函數(shù)f和g的原形，以下將f作為語句調(diào)用的是（ b ）。a g(f(3)；b f(g(3)； c g(f(3)+2)； d p= f(g(3)1)；6設(shè)int * p2=&x，* p1=a；p2= *b；則a和b的類型分別是（ b ）。 a int * 和int b int * 和int * c int 和int * d int * 和int *7設(shè)int x；，則經(jīng)過（ c ）后，語句*px=0；可將x值置為0。 a int * px； b int const * px=&x； c int * const px=&x； d const int * px=&x

4、；8設(shè)void f1(int * m，long & n)；int a；long b；則以下調(diào)用合法的是（ b ）。 a f1(a，b)； b f1(&a，b)； c f1(a，&b)； d f1(&a，&b)；9以下結(jié)構(gòu)類型可用來構(gòu)造鏈表的是（ b ）。 a struct aa int a；int * b； b struct bb int a；bb * b； c struct cc int * a；cc b； d struct dd int * a；aa b；10使用操作符setw對數(shù)據(jù)進行格式輸出時，需要包含（ c iomanip.h c ）文件。 三、回答問題（每題4分，共20分）1設(shè)in

5、t * p；，判斷下列表達式的正確性（用t表正確，用f表錯誤）。 -+p( t ) +(p-)( f ) p- ( f ) (+p)- ( t )2請初始化一維指針數(shù)組color，其初值表初值為red，blue，white和black。char * color=red，blue，white，black3設(shè)int x 99，98，97，& y=x1；， 寫出語句 couty-,； couty*2endl；執(zhí)行結(jié)果。 98，1944設(shè)int fp(char a，int b=0，double c=100.0)；，判斷下列重載函數(shù)的正確性。（用t表正確，用f表錯誤）。int fp( )；( t ) v

6、oid fp(char)；( f ) int fp(char，int)；( f ) void fp(char，int，int)；( t )5要使語句p1=new long * ；p2=new float * 15；能正常執(zhí)行，寫出p1和p2的定義。long * p1； float * p2；四、（每題10分，共20分）1寫出下列程序的執(zhí)行結(jié)果。 # include void fun(int，int，int * )； void main() int x，y，z； fun (2，3，&x)； fun (4，x，&y)； fun (x，y，&z)； coutx,y,zendl； void fun(i

7、nt a，int b，int * c ) b*=a；*c=b-a； 4，12，442下列程序向a盤上的文本文件aaa.dat輸出0至100間的整數(shù)，請將程序補充完全。 # include # include _ void main(void) ofstream f1(void main() )； if (_!f1(或f1.fail()_) cerra：aaa.dat file not open!endl； exit(1)； for (int i=0；i=100；i+)_ f1_i ； f1. close()_； 五、1 編程求數(shù)列1，的所有大于等于0.000001的數(shù)據(jù)項之和并輸出結(jié)果。1、#
