Question

Write a program that allows the user to enter the last names of five candidates in a local election and the number of votes received by each candidate. The program should then output each candidate's name, the number of votes received, and the percentage of the total votes received by the candidate. Your program should also output the winner of the election.
i have this
#include
#include
#include
using namespace std;
int findMax(int votes[]);
void main()
{
int votes[20];
string name[10];
int total=0;
float percent[10];
int m, i, loc;
cout<<"Enter the names of candidates in local election and number of votes:"< for(int i=0;i<5;i++)
{
cin>>name[i];
cin>>votes[i];
}
for(i=0;i<5;i++)
{
total=total+votes[i];
}
for(i=0;i<5;i++)
{
percent[i]=((votes[i]/total)*100);
}
cout<<"Candidate"<<'\t'<<"VotesReceived"<<'\t'<<"% of Total Votes"< cout< for(i=0;i<5;i++)
{
cout< }
cout<<"Total:"< m=findMax(votes);
cout<<"Winner of the election is"< system("pause");
}
int findMax(int votes[])
{
int i,max,loc;
max=votes[0];
for(i=1;i<5;i++)
{
if(votes[i]>max)
{
max=votes[i];
loc=i;
}
}
return loc;
}
But, it is saying that loc is not initialized, and it is also not calculating % of total votes or the winner of the election and I don't what to do to fix it.

Answer 1

Answer:

The following fix were made to the program

1. Change void main() to int main(), then set a return value at the end of the main function;  e.g. return 0
2. Remove system("pause");  It's not needed
3. For each of the array, change their lengths to 5 i.e. int votes[5];  string name[5];   and float percent[5];
4. Lastly, calculate the percentage using: percent[i]=((votes[i]*100.0/total))

Explanation:

(1) void main implies that the main function will not return any value. So, you change it to int main() and then set the return value

(2) There is no need to pause the program, so system.("pause") is not necessary.

(3) The question says there are 5 candidates. So, we set the arrays to accommodate inputs for 5 values

(4) percent array is declared as float; 100.0 will ensure that it calculates the percentage as a float value.
