電大《C++語言程序設(shè)計》第一次作業(yè)

1、專業(yè)好文檔2009年寧波電大c+語言程序設(shè)計第一次作業(yè)一、填空題。 1一個基本語句的最后一個字符是 。 2函數(shù)調(diào)用時，實參向形參的傳送分為 和 兩種傳送方式。 3若應(yīng)用程序onefunc.cpp中只有一個函數(shù)，這個函數(shù)的名稱是 。 4變量分為全局和局部兩種， 變量沒有賦初值時，其值是不確定的。 5常量345l占用 字節(jié)存儲空間。 6執(zhí)行int i,s; for(i=8,s=0;i0;i-) s+=i; while(+i5) s+=i; 后； s的值是 。 7執(zhí)行for(int i=0;i=20;i+) cout100?100:0的值賦值給變量y的賦值語句是 。10字符串”字符串”占用 字節(jié)的空

2、間。11”firstlinen2ndline”的長度是 。12執(zhí)行int a=5,b; b=a+;后，a的值為 ，b的值為 。13假定x=10,y=6,則表達式2+x+和+y*3的值分別為 和 。14執(zhí)行coutc+15；，顯示在屏幕上的是 。15假定一個枚舉類型的定義為“enum rbab,ac=3,ad,aex=ad;”，則x的值為 。16執(zhí)行“cout143+17=143+17endl;”語句后得到的輸出結(jié)果為 。17利用操作符+，語句序列p=p+1;f=p+15;的功能可以由一個語句完成，這個語句是 。18x+yb&ab的值相同 d、與a=b的值相同 2c+字符串“abc”以 符號作為

3、結(jié)束符，需 字節(jié)的 存儲空間。（ ）。 a、 c，3 b、 c，4 c、0，3 d、0，4 3從定義unsigned var;可以看出，var是一個（ ）變量。 a、無符號短整型 b、無符號小整型 c、無符號整數(shù) d、無符號長整型 4以下合法的c+字符常量是（ ）。 a、b b、 a c、 65 d、 a 5執(zhí)行int k,d=8; k=d+*3；后，k和d的值分別為（ ）。 a、24 8 b、24 9 c、27 8 d、27 9 6以下程序的輸出結(jié)果是（ ）。 a、11 b、10 c、9 d、10 11 for(j=10;j11;j+) for(i=9;i=j-1) coutj; 7下列的常

4、值變量定義中，錯誤的是（ ）。 a、const int ll=210; b、const char ch=67 c、const double d; d、const long ld=345; 8以下程序的輸出結(jié)果是（ ）。 a、 c b、 d c、 e d、 f char ch; ch=c+5-3; cout0）|(e0) c、(e=0) d、(e!=0)三、程序改錯題。不得增加語句、刪除語句，只能在原句改正。1輸入3個數(shù)，找出其中最大一個并顯示出來。#include void main() int a,j,k,m;cout”請輸入3個整數(shù)：”;cinajk;cout”3個數(shù)中的最大的是：”;if

5、(aj) j=a;if(ak) a=k;coutaendl;2輸入10個數(shù)，計算并顯示它們的合計。#include void main()double x,s;cout”請輸入10個數(shù)：”;for(int j=0;jx; s=x;cout”合計：”s;四、編程序題。1設(shè)計一個程序，輸入4個數(shù)，找出其中最小一個并顯示出來。2輸入10個整數(shù)到一個數(shù)組中，調(diào)整這10個數(shù)在數(shù)組中的排列位置，使得其中最小的一個數(shù)成為數(shù)組的首元素，并輸出處理后的數(shù)據(jù)。五、寫出下列程序運行后的輸出結(jié)果。1#include void main() int s=0; for(int i=1;i6;i+) s+=i*i; cou

6、t”s=”sendl;2#include void main() int n=10,y=1; while(n-) y+;+y; cout”y*y=”y*yendl;3#include void sb(char ch) switch(ch)case a: case a: cout”well!”;break; case b: case b: cout”good!”;break; case c: case c: cout”pass!”;break; default: cout”bad!”;break;void main() char a1=b,a2=c,a3=f; sb(a1);sb(a2);sb(

8、四、編程題。1. #include void main() double a,b,c,d; coutabcd; if(ab) a=b; if(ac) a=c; if(ad) a=d; cout”最大數(shù)是:”a;2. #include void main() int data10,m,j=0; cout”請輸入10個整數(shù):”; for(m=0;mdatam; for(m=1;m10;m+) if(datam0) m=data0;data0=dataj;dataj=m; coutendl; for(m=0;m10;m+) coutdatam ;五、寫出下列程序的運行結(jié)果。1. s=55 2. y*

15、rtner the disappointing news: mission aborted.the supersonic descent could happen as early as sunda.the weather plays an important role in this mission. starting at the ground, conditions have to be very calm - winds less than 2 mph, with no precipitation or humidity and limited cloud cover. the bal

16、loon, with capsule attached, will move through the lower level of the atmosphere (the troposphere) where our day-to-day weather lives. it will climb higher than the tip of mount everest (5.5 miles/8.85 kilometers), drifting even higher than the cruising altitude of commercial airliners (5.6 miles/9.

17、17 kilometers) and into the stratosphere. as he crosses the boundary layer (called the tropopause),e can expect a lot of turbulence.the balloon will slowly drift to the edge of space at 120,000 feet ( then, i would assume, he will slowly step out onto something resembling an olympic diving platform.

18、below, the earth becomes the concrete bottom of a swimming pool that he wants to land on, but not too hard. still, hell be traveling fast, so despite the distance, it will not be like diving into the deep end of a pool. it will be like he is diving into the shallow end.skydiver preps for the big jum

19、pwhen he jumps, he is expected to reach the speed of sound - 690 mph (1,110 kph) - in less than 40 seconds. like hitting the top of the water, he will begin to slow as he approaches the more dense air closer to earth. but this will not be enough to stop him completely.if he goes too fast or spins out of control, he ha
