Histogram

Okay, I'm on the last section of my program, and I'm stuck yet again. I need to make a histogram for the data in my program. Here is my function for it:

Code:

---

void display_histogram( int arr[], int no_items )
/*========================================================================
This function displays a histogram (bar graph) of the data in intervals of 10.
        INPUT: an array of integers, an integer which represents the number of items
        OUTPUT: this function returns nothing
========================================================================*/
{
        int counter1 = 0;
        int counter2 = 0;
        int counter3 = 0;
        int counter4 = 0;
        int counter5 = 0;
        int counter6 = 0;
        int counter7 = 0;
        int counter8 = 0;
        int counter9 = 0;
        int counter10 = 0;
        int data;

        data = arr[no_items];

        for ( int i = 0; i < no_items; i++ )
        {
                if ( data >= 0 && data <= 10 )
                {
                        counter1++;
                }

                if ( data >= 11 && data <= 20 )
                {
                        counter2++;
                }

                if ( data >= 21 && data <= 30 )
                {
                        counter3++;
                }

                if ( data >= 31 && data <= 40 )
                {
                        counter4++;
                }

                if ( data >= 41 && data <= 50 )
                {
                        counter5++;
                }

                if ( data >= 51 && data <= 60 )
                {
                        counter6++;
                }

                if ( data >= 61 && data <= 70 )
                {
                        counter7++;
                }

                if ( data >= 71 && data <= 80 )
                {
                        counter8++;
                }

                if ( data >= 81 && data <= 90 )
                {
                        counter9++;
                }

                if ( data >= 91 && data <= 100 )
                {
                        counter10++;
                }
        }

        cout << " 1 -  10:  " << counter1 << endl;
        cout << "11 -  20:  " << counter2 << endl;
        cout << "21 -  30:  " << counter3 << endl;
        cout << "31 -  40:  " << counter4 << endl;
        cout << "41 -  50:  " << counter5 << endl;
        cout << "51 -  60:  " << counter6 << endl;
        cout << "61 -  70:  " << counter7 << endl;
        cout << "71 -  80:  " << counter8 << endl;
        cout << "81 -  90:  " << counter9 << endl;
        cout << "91 - 100:  " << counter10 << endl << endl;
}

This isn't working, although I'm not really sure if it even should. The

Code:

---

data = arr[no_items];

---

line especially seems off to me. Also, is there any way I can take the numbers stored in each counter variable and use them to display the appropriate number of asterisks next to each interval of 10?

Code:

---

data = arr[no_items];  //delete this

for ( int i = 0; i < (no_items - 1); i++ )
{
    data = arr[i];

    if ( data >= 0 && data <= 10 )
    {
        counter1++;
    }

    .....and so on ....
    note: You could reconstruct this to an if-else statement and
    you won't need to check both lower and upper limit for data's
    value each run. I leave it to you to figure that out.

Construct a for loop than runs as many times as the value of the counter; print an asterisk for each run.
