C语言多功能模块设计

1、算法应用、总模块设计、功能模块程序总菜单:#inelude<stdio.h>#include<stdlib.h>externvoidmenu1();externvoidmenu2();externvoidmenu3();voidmain()intchoice;while(1)system("CLS");printf("n");printf("n");printf("*printf("菜单n");printf(”n");printf(”1.简单数据应用n");pr

2、intf(”2.递推应用n”);printf(”3.枚举应用n");printf(”0.退出n”);printf("printf("*n");printf(”请输入序号：");scanf("%d",&choice);switch(choice)case1:menu1();break;case2:menu2();break;case3:menu3();break;case0:return;1. 简单数据应用：#include<stdio.h>#include<stdlib.h>externvoi

3、dgcdn();externvoidzhaoshu();voidmenu1()while(1)intchoice1;system("CLS");printf("n");printf("n");printf("简单数据应用n");printf("n");printf("1.最大公约数n");printf("2.排序找数n");printf("0.返回n");printf("n");printf("请输入序号：

4、");scanf("%d",&choice1);switch(choice1)case1:gcdn();break;case2:zhaoshu();break;case0:return;2. 递推应用：#include<stdio.h>#include<stdlib.h>externvoidgcdn();externvoidzhaoshu();voidmenu2()intchoice2;While(1)system("CLS");printf("n");printf("n"

5、);printf("递推应用n");printf("n");printf("1.兔子繁殖n");printf("2.捕鱼问题n");printf("0.返回n");printf("n");printf("请输入序号：");scanf("%d",&choice1);switch(choice1)case1:tuzi();break;case2:buyu();break;case0:return;枚举应用：#include<s

6、tdio.h>#include<stdlib.h>externvoidgcdn();externvoidzhaoshu();voidmenu2()intchoice3;While(1)system("CLS");printf("n");printf("n");printf("枚举应用n");printf("n");printf("1.兑币问题n");printf("2.八皇后问题n");printf("0.返回n");

7、printf("n");printf("请输入序号：");scanf("%d",&choice1);switch(choice1)case1:duibi();break;case2:bahuanghon();break;case0:return;三、各子功能设计最大公约数#include<stdio.h>#include<stdlib.h>intgcd(intn)inta,b,r,i;printf("nNumber1:");scanf("%d",&b);f

8、or(i=1;i<n;i+)printf("Number%d:",i+1);scanf("%d",&a);r=a%b;while(r!=0)a=b;b=r;r=a%b;return(b);voidgcdn()intx,n1;system("CLS");printf("请输入数的个数:n");scanf("%d",&n1);x=gcd(n1);printf("最大公约数:%dn",x);system("PAUSE");system(&q

9、uot;CLS");return;a. 排序找数#include<stdio.h>#include<string.h>#include<stdlib.h>#defineN30voiddeldit(char*s)intk;k=1;while(sk!='0')if(sk-1>sk)break;k+;if(sk='0')sk-1='0'return;k-;dosk=sk+1;k+;while(sk!='0');return;voidsortpro(char*s)inti,j,k,len

10、;charstmp;len=strlen(s);for(i=0;i<len-1;i+)k=i;for(j=i+1;j<len;j+)if(sk>sj)k=j;if(k!=i)stmp=sk;sk=si;si=stmp;voidzhaoshu(void)intd,s,len,i,k,m;charstrN+1,stmp;system("CLS");scanf("%d",&d);while(d->0)scanf("%s%d",str,&s);for(i=0;i<s;i+)deldit(str);

11、len=strlen(str);k=len-1;while(k>0)if(strk>strk-1)break;k-;if(k=0)printf("0n");return;for(m=k,i=k+1;i<len;i+)if(stri>strk-1&&stri<strm)m=i;stmp=strk-1;strk-1=strm;strm=stmp;sortpro(&strk);printf("%sn",str);system("PAUSE");b. 兔子繁殖：#include<st

12、dio.h>intmain()inti,n,f37;scanf("%d",&n);f1=1;f2=2;for(i=3;i<=n;i+)fi=fi-1+fi-2;printf("第%d个月有%d对兔子n",n,fn);return0;捕鱼问题：#include<stdio.h>intmain()inti,n,f5,flag;flag=1;n=1;while(flag!=0)f0=5*n+1;flag=O;for(i=1;i<5;i+)if(fi-1%4!=0)flag=1;break;fi=5*fi-1/4+1;n+;

13、printf("5个人至少捕到%d条鱼n”,f4);return0;c. 兑币问题:100元的整币整币兑换问题。有1角、2角、5角、1元、5元共5种零币，现要将一张换成零币，问共有多少种不同的兑换方案。#include<stdio.h>voidmain()intp1,p2,p5,p10,p20,p50,n,m;n=100;m=0;for(p2=0;p2<=n/2;p2+)for(p5=0;p5<=n/5;p5+)for(p10=0;p10<=n/10;p10+)for(p20=0;p20<=n/20;p20+)for(p50=0;p50<=n

14、/50;p50+)p1=n-(2*p2+5*p5+10*p10+20*p20+50*p50);if(p1>=0)m+;printf("%dn",m);d. 八皇后问题:printf("%ld",a);n+;if(n%6=0)printf("n");printf("n%dn",n);intchk18(longm)intf10,i,fg;for(i=0;i<10;i+)#include<stdio.h>#include<math.h>voidmain()intn=0;longa;for(a=12345678;a<=87654321;a+)if(chk18(a)=0)continue;if(chkdia(a)=0)continue;fi=0；while(m!=O)fm%10+;m=m/10;for(fg=1,i=1;i<=8;i+)if(fi!=1)fg=O;break;retur
