编程统计候选人的得票数。设有3个候选人zhang、li、wang(候选人姓名不区分大小写),
10个选民,选民每次输入一个得票的候选人的名字,若选民输错候选人姓名,则按废票处理。
选民投票结束后程序自动显示各候选人的得票结果和废票信息。要求用结构体数组candidate
表示3个候选人的姓名和得票结果。
例如:
Input vote 1:li
Input vote 2:li
Input vote 3:Zhang
Input vote 4:wang
Input vote 5:zhang
Input vote 6:Wang
Input vote 7:Zhang
Input vote 8:wan
Input vote 9:li
Input vote 10:lii
Election results:
li:3
zhang:3
wang:2
Wrong election:2
输入格式:
"Input vote %d:"
"%s"
输出格式:
"Election results:\n"
"%8s:%d\n"
"Wrong election:%d\n"
注意:
A. 上述输出格式中,"%8s:%d\n"中%8s表示输出候选人的姓名;%d表示输出相应候选人的的票数。
B. 另外,无论是否存在废票的情况,最终都需要输出"Wrong election:%d\n"。
C. 本题要求使用结构体。

#include<stdio.h>
#include<string.h>
typedef struct vote
{
char name[10];
int count;
} VOTE;
main()
{
VOTE vote[10]={{"li",0},{"zhang",0},{"wang",0},{"Zhang",0},{"Wang",0}};
int i;
char name[10];
for (i = 0; i < 10; i++)
{
printf("Input vote %d:", i + 1);
scanf("%s", name);
if (strcmp(vote[2].name, name) == 0 || strcmp(vote[4].name, name) == 0)
vote[2].count++;
else if (strcmp(vote[0].name, name) == 0)
vote[0].count++;
else if (strcmp(vote[3].name, name) == 0 || strcmp(vote[1].name, name) == 0)
vote[1].count++;
else
vote[3].count++;
}
printf("Election results:\n");
for (i = 0; i < 3; i++)
{
printf("%8s:%d\n", vote[i].name, vote[i].count);
}
printf("Wrong election:%d\n", vote[3].count);
}
