Can anybody give me the test case 1?

Have you tried task example?

Have you received the same output as in example?

Yes, my code gives the same output for sample test case. Here is my code-

#include <iostream>
#include<iomanip>
using namespace std;

int main()
{
    int n, m, vote;
    cin>>n>>m;
    int *candidates = new int[n];
    for(int i=0; i<m; i++)
    {
        cin>>vote;
        candidates[vote-1]++;
    }

    for(int j=0; j<n; j++)
    {
        cout<<fixed<<setprecision(2)<<float(float(candidates[j]*100)/m)<<"%"<<endl;
    }

    return 0;
}

1) What is initial value for "candidates" items? Isn't it undefined?
2) Here is my local run output:
3 6
1 1 1
2 2 3
--------
280716864.00%
280716832.00%
280716832.00%

Looks like output is broken, it's visible. Have you tried to run program locally before crying in chat? Why not?

3) Why "candidates" is raw pointer? You should use vector/shared_ptr/scoped_ptr<int[]>. Or at least release array manually.

The problem was uninitialized candidates array. It worked perfectly on my local machine as the compiler I used initialized it to 0 automatically. Thanks.
