法律研究编写一个 C 程序，使用 Switch case 调用函数来选举候选人
问题
如何使用 C 语言为参加选举的每位候选人投票、统计和显示得票数？
解决方案
我们考虑一下三位参加选举的人。这里我们需要为以下部分编写代码 -
投票 - 按下投票键选择候选人
查找得票数 - 查找每位候选人获得的总得票数，并宣布获胜者。
示例
使用 Switch case 调用每个函数来执行所有这些操作 -
#include<stdio.h>
#define CANDIDATE_COUNT
#define CANDIDATE1 "ABC"
#define CANDIDATE2 "XYZ"
#define CANDIDATE3 "PQR"
int votescount1=0, votescount2=0, votescount3=0;
void castvote(){
int choice;
printf("
### Please choose your Candidate ####
");
printf("
1. %s", CANDIDATE1);
printf("
2. %s", CANDIDATE2);
printf("
3. %s", CANDIDATE3);
printf("
4. %s", “None of These");
printf("
Input your choice (1 - 4) : “);
scanf("%d",&choice);
switch(choice){
case 1: votescount1++; break;
case 2: votescount2++; break;
case 3: votescount3++; break;
default: printf("
Error: Wrong Choice !! Please retry");
//hold the screen
getchar();
}
printf(“
thanks for vote !!");
}
void votesCount(){
printf("
##### Voting Statics ####");
printf("
%s - %d ", CANDIDATE1, votescount1);
printf("
%s - %d ", CANDIDATE2, votescount2);
printf("
%s - %d ", CANDIDATE3, votescount3);
}
int main(){
int i;
int choice;
do{
printf("
###### Welcome to Election/Voting 2019 #####");
printf("
1. Cast the Vote");
printf("
2. Find Vote Count");
printf("
0. Exit");
printf("
Please enter your choice : ");
scanf("%d", &choice);
switch(choice){
case 1: castvote();break;
case 2: votesCount();break;
default: printf("
Error: Invalid Choice");
}
}while(choice!=0);
//hold the screen
getchar();
return 0;
}输出
