1、程序设计基础课程设计实验报告班级：1303011姓名：洪礼翔学号：13030110019所选题目：1_1, 1_2,2_4,3_2,3_4,4_2,5_1程序设计语言：c+程序设计平台：visual c+ 6.0日期：2014-4-5签名：第1_1题 算法描述：比较两个文本文件并打印出它们第一个不相同的行（文件每行字符数不多于80）。源程序：no1_1.cpp#include#include#include#includevoid main()fstream infile1,infile2;infile1.open(f1.txt,ios:in);infile2.open(f2.txt,ios:
2、in);if(!infile1)coutf1.txt cant open;abort();if(!infile2)coutf2.txt cant open;abort();char s180,s280;while(!infile1.eof()&!infile2.eof()infile1.getline(s1,sizeof(s1);infile2.getline(s2,sizeof(s2);if(strcmp(s1,s2)couts1endl;couts2endl;infile1.close();infile2.close();测试数据（输入、输出）： 第1_2题 算法描述：文本文件num1.t
3、xt和num2.txt中各有一组用空格分隔的整数，将num1.txt和num2.txt联合排序，并将结果保存在num3.txt中源程序：no1_2.cpp #include#include#include#includeint cmp(const void *m,const void *n);void main()fstream inf1,inf2,outf;inf1.open(num1.txt,ios:in);if(!inf1)coutnum1.txt cant open.n;abort();inf2.open(num2.txt,ios:in);if(!inf2)coutnum2.txt c
4、ant open.n;abort();outf.open(num3.txt,ios:out);if(!outf)coutarrayi+;while(!inf2.eof()inf2arrayi+; qsort(array,i,sizeof(int),cmp);int j(0);while(i)outfarrayj+;if(i!=1) outf ;i-;coutSort correctlly!n;int cmp(const void *m,const void *n)return *(int *)m-*(int *)n;测试数据（输入、输出）：第2_4题 算法描述：编写程序XMLtoTXT自动将X
5、ML文件email.xml转换为文本文件email.txt。命令行格式：XMLtoTXT email.xml email.txt。源程序：No2_4.cpp#include#include#include#includevoid main()fstream infile,outfile;infile.open(email.xml,ios:in);if(!infile)coutemail.xml cant open.n;abort();outfile.open(email.txt,ios:out);if(!outfile)coutemail.txt cant open.n;abort();cha
6、r ch=0;int state=0;coutProgressing.endl;while(ch=infile.get()!=EOF)char str10=0;if(ch=;i+)stri=infile.get();if(!strcmp(str,from) state=-1;if(state=-1&!strcmp(str,address) state=1;if(!strcmp(str,to) state=-2; if(state=-2&!strcmp(str,address) state=2;if(!strcmp(str,subject) state=3;if(!strcmp(str,body

8、述：设计一个复数类型，输入实部和虚部生成一个复数，可进行两个复数求和、两个复数求差、两个复数求积运算。源程序：No3_2.cpp#includeclass complexpublic:complex()set(0.0,0.0);complex(double real, double imag)set(real,imag);void set(double r, double i)real=r;imag=i;friend complex operator +(const complex &c1,const complex &c2);friend complex operator -(const c
9、omplex &c1,const complex &c2);friend complex operator *(const complex &c1,const complex &c2);void print();private:double real, imag;void complex:print()if(imag0)coutrealimagiendl;elsecoutreal+imagiendl;complex operator +(const complex &c1,const complex &c2)return complex(c1.real+c2.real,c1.imag+c2.i
10、mag);complex operator -(const complex &c1,const complex &c2)return complex(c1.real-c2.real,c1.imag-c2.imag);complex operator *(const complex &c1,const complex &c2)return complex(c1.real*c2.real-c1.imag*c2.imag, c1.real*c2.imag+c1.imag*c2.real);void main()complex a,b,c;double r,i;coutComplex a:n;coutr;couti;a.set(r,i);couta=;a.print();coutComplex b:n;coutr;couti;b.set(r,i);coutb=;b.print();int s;coutFunction:nn;cout1.c=a+b 2.c=a-b 3.c=a*bns;switch(s)case 1: c=a+b;break;case 2: c=a-b;break;case 3: c=a*b;break;default:coutPlease enter 1,2or3!n;goto Input;coutnc=;c.print();测试数据（输入、输出
