选票统计程序。候选人及候选人代码如图所示：=========选票==========
1. 张三
2. 李四
3. 王五
=======================
请输入票面（-1退出，其它废票）：
1 ↙
3 ↙
2 ↙
2 ↙
4 ↙
……
-1 ↙
= = = = 统计结果 = = = =
张三 × 票
李四 × 票
王五 × 票
= = = = = = = = = = = = =
#include<stdio.h>
#define MAX 3 //定义最大人数
int main()
{
int i, a[MAX] = {0};
int j = 0;
printf("=========选票==========\n");
printf("1. 张三\n");
printf("2. 李四\n");
printf("3. 王五\n");
printf("=======================\n");
printf("请投票（-1退出，其它废票）：\n");
while (1)
{
scanf("%d", &i);
if (i == -1)
{
break;
}
if ((i > MAX) || (i < 1))
{
j++;//废票
continue;
}
a[i-1]++;
}
printf("= = = = 统计结果 = = = =\n");
printf("张三 %d票\n", a[0]);
