I am really close to getting this function to work. This function is to display a horizontal bar chart for quiz score values (from lowest score to largest score) to appear across the page and asterisk type bars are displayed vertically.
The output I get is below (with array values a[35]=5, a[50]=2, a[41]=6, a[42]=3, a[48]=4, a[42]=2) So int low = 35, int high = 50, int freq = 6). The asterisk for the score of 35 and 41 is correct. However, asterisk for the score of 42 is somehow shifted to the right.
//This function takes in an array of integers, an integer for the lowest score, an integer for the highest
//score, and an integer for the largest frequency. It then outputs a readable bar chart graph in a horizontal
//arrangement where the quiz score values appear across the page and the asterisks are displayed vertically..
void horizontalBarChart(int a[], int low, int high, int freq)
{
cout << "Frequency: Score Horizontal Bar Chart" << endl;
cout << " " << endl; //spacing
for (int i = freq; i >= 1; i--) //frequency starting from high to low
{
cout << " " << "^" << " " << i << ":";
for (int j = low; j <= high; j++) //looping through array
{
if (i == a[j]) //if frequency at index is less than or equal to frequecy count (not inlcuding 0 frequencies)
{
int spaces = (((j - low) + 1) * 3); //number of spaces over to print asterisk
for (int k = 1; k <= spaces; k++) //printing number of spaces over
{
cout << " "; //print space
}
cout << "*"; //print asterisk
}
}
cout << endl;
}
cout << "---------: "; //prints axis
for (int i = 0; i < ((high - low) + 1); i++)
{
cout << "--^";
}
cout << endl;
cout << " Score:" << " "; //prints axis
for (int i = low; i <= high; i++)
{
cout << i << " ";
}
cout << endl;
}
