1、12年C+語言上半學(xué)期綜合訓(xùn)練題第三局部：填代碼題3-1.下面是有關(guān)字符串的程序，請補充代碼。#include void main()(char a=nasdfghjkl,b20;for (int i=0;*(a+i) ! = ,0*;i+)/將a的內(nèi)容逐項拷貝到b/字符串b結(jié)尾coutnString a is:n;for(i=0;ai!=101;i+) couta i;coutendl;coutHString b is:;/輸出字符串b)3-2.下面程序是交換變量a和b值，請補充代碼。#includevoid swap () /補充形參 ( 臨時變量定義temp二*pl;*pl=*p2;*p

2、2=temp;)void main ()(int a(3), b(4);cout bendl;/ pl、p2賦值swap (pl, p2);couta， bcndl;3-3.以下為有關(guān)字符串的程序，請補充代碼。#include void link ()/函數(shù)的說明(for (int i=0;stringli ! =0;i+)/將stringl的字符拷貝給stringfor (int j =0;string2j ! = *0 *;j +)/將string2的字符拷貝給string /添加結(jié)束符)void main()(char sl100,s2100fs100;coutsl;couts2;lin

3、k(si,s2,s);coutnthe new string is: s;)3-4.以下為有關(guān)整數(shù)運算的程序，請補充代碼。#include#includedouble SD (int a, int b,) / 填寫形參說明(double x=0.0;switch(op)(case + *: x= double(a)+b; break;case- 1:x=double(a)-b; break;case* *：x=double(a)*b; break;case/* :if ( ) exit (-1) ; /除法的條件else x = double(a)/b;break;default: exit

4、(-2);return x;void main() (int x=20, y=5;coutSD(x, y, r + *) * *;coutSD(xz yz *) * ; coutSD(x-yz yz */*)endl;輸出結(jié)果：3-5.有程序如下：void LG (, int m) / 數(shù)組 a(a = new intm;int *p = a;for (int i=0; im; i+) *p+ = i*i+l;void main() (int ; /說明指針b并初始化int n=5;LG(b, n);for (int i=0; in; i+) coutbi ;coutendl; delete

5、b;)輸出結(jié)果：3-6.有關(guān)鏈表的程序如下，請補充適當(dāng)代碼。#include struct StrNode (char name 15;/字符串域 StrNode*next; 指針域）；void 工nput (, int n) / 鏈表指針 f (if( n = 0 ) f = NULL; return;)f = new StrNode;cin f-name;StrNode* p=f;while(-n) (p-next = new StrNode;/將p移動到新的結(jié)點 cin p-name;)p-next=NULL;)void Print (, int n) / 鏈表指針 p(while (n-)(/如果鏈表指針為空，退出循環(huán) cou
