c语言选票程序怎么编写,用while写法?

首先需求分析:

投票人票数多少,一对一投或一对多。

由于你问题需求不明确,我按照投票人每人1票,只给1个候选人投票或弃权。

函数功能分三个,分别:

一、初始化(这个函数改成输入就是信息登记模块)。

二、投票函数(我用随机数实现投票过程)。

三、统计投票结果。

下面是代码:

#include stdio.h

#include stdlib.h

#include string.h

#include time.h

#define MCDE 5//候选人数量

#define MVR 100//投票人数量

typedef struct candidate

{

  char name[20];//候选人名称

  int vote;//得票数

}CDE;

typedef struct voter

{

  char name[20];//投票人名称

  int vote;//票数

}VTR;

void init(CDE **cdep,VTR **vtrp);//初始化候选人及投票人信息

void tp(CDE *cdes,VTR *vtrs);//开始投票(随机)

void tj(CDE *cdes,VTR *vtrs);//统计投票结果

int main()

{

  CDE *cdes=NULL;

  VTR *vtrs=NULL;

  init(cdes,vtrs);

  tp(cdes,vtrs);

  tj(cdes,vtrs);

  return 0;

}

void tj(CDE *cdes,VTR *vtrs)

{

  int i=100,index,waiver=0,max=0,inxSave;

  while(i0)

  {

      index=MVR-i;

      if(vtrs[index].vote==-1)

          waiver++;

      i--;

  }

  printf("\n\n共%d人参与投票,%d人弃权\n",MVR-waiver,waiver);

  i=MCDE;

  while(i0)

  {

      index=MCDE-i;

      printf("候选人%s得票%d张\n",cdes[index].name,cdes[index].vote);

      if(maxcdes[index].vote)

          max=cdes[index].vote,inxSave=index;

      i--;

  }

  printf("得票最多的候选人为:%s,%d票\n",cdes[inxSave].name,cdes[inxSave].vote);

}

void tp(CDE *cdes,VTR *vtrs)

{

  int i=MVR,index,n,n2;

  srand(time(NULL));

  while(i0)

  {

      index=MVR-i;

      if(vtrs[index].vote0)

      {

          n=rand()%MCDE;//随机0~MCDE-1,给对应候选人投票

          n2=rand()%2;//随机0~1,1投票,0弃权

          if(n2)

          {

              printf("%s给候选人:%s投了%d票\n",vtrs[index].name,cdes[n].name,vtrs[index].vote);

              cdes[n].vote+=vtrs[index].vote;

              vtrs[index].vote=0;

          }

          else

          {

              printf("%s选择弃权\n",vtrs[index].name);

              vtrs[index].vote=-1;

          }

      }

      i--;

  }

}

void init(CDE **cdep,VTR **vtrp)

{

  static CDE cdes[MCDE]={{"小王",0},{"小陈",0},{"小李",0},{"小丽",0},{"小艾",0}};

  static VTR vtrs[MVR];

  int i=MVR,index;

  char strN[20];

  while(i0)

  {

      index=MVR-i;

      strcpy(vtrs[index].name,"投票人");

      itoa(index+1,strN,10);

      strcat(vtrs[index].name,strN);

      vtrs[index].vote=1;

      i--;

  }

  *cdep=cdes,*vtrp=vtrs;

}
