hey again i have small problem i need help i want to print the "year with greatest and smallest increase and decrease" the years are from 2000 to 2009. i know how to print the greatest and smallest number in the array but i don't know how to print the year. here is half of the code of the program the one that's important for you.

void maxIncDecYears(int annualIncome[],int arraySize){
    year = 2000;

    int max = annualIncome[0],min = annualIncome[0];

    for(int z = 1; z < arraySize; z++){
        if(max < annualIncome[z]){
            max = annualIncome[z];
            year++;
        }

    }
    cout << "Year with maximum income increased: " << year << endl;

    year = 2000;

    for(int x = 1; x < arraySize; x++){
        if(min > annualIncome[x]){
            min = annualIncome[x];
            year++;
        }

    }
    cout << "Year with maximum income decreased: " << year << endl;
}

void maxIncDecYears(int annualIncome[],int arraySize)
{
    int greater_year = 2000;
    int min_year = 2000;

    int max = annualIncome[0],min = annualIncome[0];

    for(int z = 1; z < arraySize; z++){
        if(max < annualIncome[z]){
            max = annualIncome[z];
            greater_year++;
        }

    }
    cout << "Year with maximum income increased: " << greater_year << endl;

    min_year = 2000;

    for(int x = 1; x < arraySize; x++){
        if(min > annualIncome[x]){
            min = annualIncome[x];
            min_year++;
        }

    }
    cout << "Year with mimum income decreased: " << min_year << endl;
}

one quick question ..why are you passing array to the function when you are using only int .. it effact the performance
