Mode of Array C++ - c++

Question

My code to find the mode (most often) and how many times said mode was displayed runs into a never-ending loop. Does anyone know what I can do to fix it?
EDIT I UPDATED THE CODE: It returns 0, which is not the mode.
void calculateMode(int array[], int size)
{
int counter = 0;
int max = 0;
int mode = 0;
for (int pass = 0; pass < size - 1; pass++)
for (int count = pass + 1; count < size; count++) {
if (array[count] > max) {
max = array[count];
mode = 1;
counter = array[pass];
}
cout << "The mode is: " << counter "It's been displayed: " << count << "times" << endl;
}

A solution using map. Compile with g++ -std=c++11 a.cpp.
Here is definition of mode
#include <iostream>
#include <map>
#include <vector>
using namespace std;
int main()
{
vector<int> v = {1, 1, 2, 2, 3, 3};
map<int, int> count;
for (size_t i = 0; i < v.size(); ++i)
count[v[i]]++;
vector<int> mode;
int cnt = 0;
for (map<int, int>::iterator it = count.begin(); it != count.end(); ++it) {
if (it->second > cnt) {
mode.clear();
mode.push_back(it->first);
cnt = it->second;
} else if (it->second == cnt) {
mode.push_back(it->first);
}
}
if (mode.size() * cnt == v.size()) {
cout << "No mode" << endl;
} else {
cout << "mode:";
for (size_t i = 0; i < mode.size(); ++i)
cout << ' ' << mode[i];
cout << endl;
}
return 0;
}

This code uses "map" to find out the MODE from the given array. I hope this solution might help you.
int findMode(int * arr, int size)
{
map<int, int> modeMap;
sort(arr, arr + size);
for (int i = 0; i < size; ++i) {
++modeMap[arr[i]];
}
auto x = std::max_element(modeMap.begin(), modeMap.end(),
[](const pair<int, int>& a, const pair<int, int>& b) {
return a.second < b.second; });
return x->first;
}
