I need programming help?

I am working on this program that uses an array of structs and im trying to find the smallest and largest if the number of planes landed but the way i wanna do it is not working ... please help me

#include <iostream>

using namespace std;

struct aircraft

{

int landed;

int departed;

int greatestLanded;

int leastLanded;

};

int main()

{

aircraft plane[6];

int sum = 0;

float avg[2];

int smallest = 99;

int largest = 0;

int smMonth = 0;

int lgMonth = 0;

//loop asks the user those questions 12 times

for(int count = 0; count < 6; ++count)

{

cout << "In month " << (count + 1) << ", how many planes landed? ";

cin >> plane[count].landed;

cout << "In month " << (count + 1) << ", how many planes departed? ";

cin >> plane[count].departed;

cout << "In month " << (count + 1) << ", what is the greatest amount of planes landed in one given day? ";

cin >> plane[count].greatestLanded;

cout << "In month " << (count + 1) << ", what is the fewest amount of planes landed in one given day? ";

cin >> plane[count].leastLanded;

cout << endl;

}

//adds up the total of planes landed

for (int count = 0; count < 6; ++count)

sum += plane[count].landed;

avg[1] = sum / 6; // calculates the average of landed

cout << "The average of planes landed is " << avg[1] << endl;

sum = 0; //resets sum to zero

//adds up the total of planes departed

for (int count = 0; count < 6; ++count)

sum += plane[count].departed;

avg[2] = sum / 6; // calculates the average for departed

cout << "The average of planes departed is " << avg[2] << endl;

sum = 0;

//Calculates the total of planes landed and departed

for (int count = 0; count < 6; ++ count)

{

sum += plane[count].departed;

sum += plane[count].landed;

}

cout << "The total planes landed and departed is " << sum << endl;

//finds the largest and smallest amount of planes laneded and departed

for (int count = 0; count < 6; ++count)

{

if(plane[count].landed >= smallest)

{

plane[count].landed = smallest;

count = smMonth;

}

else if(plane[count].landed <= largest)

{

plane[count].landed = largest;

count = lgMonth;

}

}

cout << "The month with the fewest amount of planes landed is month ";

cout << smMonth << " and it had " << smallest << endl;

cout << "The month with the largest amount of planes landed is month ";

cout << lgMonth << " and it had " << largest << endl;

system("PAUSE");
