copied!<p>I'm trying to create a program that will display bar graphs with * the maximum number of * can be 40. I have everything working but had a question with the code. Is there a better way as you can see I have to go back to the original address twice using:</p> <pre><code> p_bar_length = p_bar_length - size; </code></pre> <p>Is there a better way to do this?</p> <pre><code>#include <iostream> using namespace std; const int MAX_SPLATS = 40; void bar_chart(double values[], int size) { double largest = values[0]; //assign first element to be the largest //Find the largest value for (int i = 1; i < size; i++) { if (largest < values[i]) // check to see if there is something larger { largest = values[i]; } } // Find the number of spalts to use // with the precent based on the largest value int* p_bar_length = new (nothrow) int[size]; for (int i = 0; i < size; i++) { *p_bar_length = (values[i] / largest) * MAX_SPLATS; p_bar_length++; // Go to next memory address } // Go back to the orignal memory address p_bar_length = p_bar_length - size; // Pritnt the correct number of splats for (int i = 0; i < size; i++) { for (int j = 0; j < *p_bar_length; j++) { cout << "*"; } p_bar_length++; cout << endl; } // Go back to the orignal memory address p_bar_length = p_bar_length - size; delete[] p_bar_length; } int main() { double values[6] = { 22, 40, 28, 26, 14, 46}; int val_size = 6; bar_chart(values, val_size); system("pause"); return 0; } </code></pre>
