Beginner C++ visual studio

standard template library = STL

Write a program that allows the user to enter the last names of five candidates in a local election and the votes received by each candidate. The program should then output each candidate’s name, the votes received by that candidate, and the percentage of the total votes received by the candidate. Your program should also output the winner of the election.

First design a Vote structure to hold candidate, votes received and percentage of total votes. Then use a STL list of Vote structure to implement the program. Whenever possible, you should use STL functions and/or iterators to accomplish the necessary operations. Otherwise, you can not get credit for your implementation. Design the program top-down, with only function calls in main, and function calls within functions.

Explanation / Answer

Here is the program in C plus plus which will solve your question.

#include <iostream>
#include <string>

using namespace std;

int findWinner(int votes[]);
void printResults(string candidates[], int votes[]);
double calculatePercentage(int votes[], int vote);

const int NUMBER_OF_CANDIDATES = 5;

int main()
{
  
string candidates[NUMBER_OF_CANDIDATES];
int votes[NUMBER_OF_CANDIDATES];
  
cout << "Please input the 5 candidates followed by the votes they recieved i.e. Smith 5000: ";
for (int i = 0; i < NUMBER_OF_CANDIDATES; i++) {
cin >> candidates[i] >> votes[i];
}
printResults(candidates, votes);
cout << "And the winner is: " << candidates[findWinner(votes)] << endl;
return 0;
}

double calculatePercentage(int votes[], int vote){
int sumOfVotes = 0;
  
for (int i = 0; i < NUMBER_OF_CANDIDATES; i++) {
sumOfVotes += votes[i];
}
  
double percentage = static_cast<double>(vote) / sumOfVotes;
  
return percentage*100;
}

void printResults(string candidates[], int votes[]){
cout << "Name:" << setw(15) << "Votes:" << setw(15) << "Percentage:" << endl;
for (int i = 0; i < NUMBER_OF_CANDIDATES; i++) {
cout << candidates[i] << setw(15) << votes[i] << setw(15);
int percentage = calculatePercentage(votes, votes[i]);
cout << percentage << "%" << endl;
  
}
}

int findWinner(int votes[]){
int winner = 0;
for (int i = 0; i < NUMBER_OF_CANDIDATES; i++) {
if (votes[i] > winner)
winner = i;
}
return winner;
}
