How to solve the error: invalid conversion from " int* " to " int " - c++

Question

Need some help with the problem.
When I compile my code below, it gives me this error:
error: invalid conversion from " int* " to " int "
I want to create a calculatePercentage function, so I can use the value when I call it.
void calculatePercentage(int voteResult[],int percentage[])
const int NO_OF_CANDIDATE = 10;
int main()
{
ifstream input("votes.txt",ios::in);
string candidates[NUMBER_OF_CANDIDATE];
int voteResult[NUMBER_OF_CANDIDATE];
int percentage[NUMBER_OF_CANDIDATE];
for (int i = 0; i < NUMBER_OF_CANDIDATE; i++) {
input >> candidates[i] >> voteResult[i];
}
calculatePercentage(voteResult, percentage); // error happened here.
return 0;
}
void calculatePercentage(int voteResult[],int percentage[])
{
int totalVotes = 0;
for (int i = 0; i < NUMBER_OF_CANDIDATE; i++)
{
totalVotes += votes[i];
}
for (int j = 0; j < NUMBER_OF_CANDIDATE; j++)
{
double wk_percentage = static_cast<double>{votes[j])/totalVotes;
percentage[j]=static_cast<int>(wk_percentage*100);
}
}

Answer 1

The code you posted has a bunch of errors.
calculatePercentage() definition is missing the closing ';'
probable name mismatch between NO_OF_CANDIDATE and NUMBER_OF_CANDIDATE
missing #include <fstream> (using ifstream)
missing #include <string>
missing std:: namespace before ifstream and string
votes not declared anywhere (should it be voteResult?)
wrong opening curly bracket instead in static_cast<double>{votes[j])/totalVotes;
...
Let alone the way you do calculation and parameter passing...
The following edited code should compile, not sure if it works as you expected:
#include <fstream>
#include <string>
void calculatePercentage(int voteResult[], int percentage[]);
const int NUMBER_OF_CANDIDATE = 10;
int main()
{
std::ifstream input("votes.txt");
std::string candidates[NUMBER_OF_CANDIDATE];
int voteResult[NUMBER_OF_CANDIDATE];
int percentage[NUMBER_OF_CANDIDATE];
for (int i = 0; i < NUMBER_OF_CANDIDATE; i++) {
input >> candidates[i] >> voteResult[i];
}
calculatePercentage(voteResult, percentage); // error happened here.
return 0;
}
void calculatePercentage(int voteResult[], int percentage[])
{
int totalVotes = 0;
for (int i = 0; i < NUMBER_OF_CANDIDATE; i++)
{
totalVotes += voteResult[i];
}
for (int j = 0; j < NUMBER_OF_CANDIDATE; j++)
{
double wk_percentage = static_cast<double>(voteResult[j]) / totalVotes;
percentage[j] = static_cast<int>(wk_percentage*100);
}
}

Answer 2

Thanks for everyone's comment. I skipped some statements and made some typos when posting them. I fixed them as follows. The only error occurred is that still cannot convert " int* " from " int". Just don't know how to solve it.
#include <fstream>
#include <iostream>
#include <iomanip>
#include <string>
using namespace std;
void calculatePercentage(int voteResult[],int percentage[]);
const int NUMBER_OF_CANDIDATE = 10;
int main()
{
ifstream input("votes.txt",ios::in);
string candidates[NUMBER_OF_CANDIDATE];
int vote[NUMBER_OF_CANDIDATE];
int percentage[NUMBER_OF_CANDIDATE];
for (int i = 0; i < NUMBER_OF_CANDIDATE; i++) {
input >> candidates[i] >> vote[i];
}
calculatePercentage(voteResult, percentage); // error happened here.
return 0;
}
void calculatePercentage(int voteResult[],int percentage[])
{
int totalVotes = 0;
for (int i = 0; i < NUMBER_OF_CANDIDATE; i++)
{
totalVotes += votes[i];
}
for (int j = 0; j < NUMBER_OF_CANDIDATE; j++)
{
double wk_percentage = static_cast<double>(votes[j])/totalVotes;
percentage[j]=static_cast<int>(wk_percentage*100);
}
}
