Write a C program for electing a candidate in Elections by calling functions using Switch case


Problem

How to cast vote, count, and display the votes for each candidate that participates in elections using C language?

Solution

Let’s consider three persons who participated in elections. Here we need to write a code for the following −

  • Cast vote − Selecting a candidate by pressing the cast vote

  • Find vote count − Finding the total number of votes each candidate gains declaring the winner.

Example

All these operations are performed by calling each function using Switch case −

#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; }
