c語言選票程序怎麼編寫，用while寫法？
首先需求分析：
投票人票數多少，一對一投或一對多。
由於你問題需求不明確，我按照投票人每人1票，只給1個候選人投票或棄權。
函數功能分三個，分別：
一、初始化(這個函數改成輸入就是信息登記模塊)。
二、投票函數(我用隨機數實現投票過程)。
三、統計投票結果。
下面是代碼：
#include stdio.h
#include stdlib.h
#include string.h
#include time.h
#define MCDE 5//候選人數量
#define MVR 100//投票人數量
typedef struct candidate
{
char name[20];//候選人名稱
int vote;//得票數
}CDE;
typedef struct voter
{
char name[20];//投票人名稱
int vote;//票數
}VTR;
void init(CDE **cdep,VTR **vtrp);//初始化候選人及投票人信息
void tp(CDE *cdes,VTR *vtrs);//開始投票（隨機）
void tj(CDE *cdes,VTR *vtrs);//統計投票結果
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人參與投票，%d人棄權\n”,MVR-waiver,waiver);
i=MCDE;
while(i0)
{
index=MCDE-i;
printf(“候選人%s得票%d張\n”,cdes[index].name,cdes[index].vote);
if(maxcdes[index].vote)
max=cdes[index].vote,inxSave=index;
i–;
}
printf(“得票最多的候選人為：%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;//隨機0~MCDE-1，給對應候選人投票
n2=rand()%2;//隨機0~1，1投票，0棄權
if(n2)
{
printf(“%s給候選人：%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選擇棄權\n”,vtrs[index].name);
vtrs[index].vote=-1;
}
}
i–;
}
}
void init(CDE **cdep,VTR **vtrp)
{
static CDE cdes[MCDE]={{“小王”,0},{“小陳”,0},{“小李”,0},{“小麗”,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;
}
