Hi everyone,
I am working on a code that generates n evenly spaced nodal points from a to b. It runs but I can't get to add interval to itself every iteration, and I am not sure if I got the formula right.
Any ideas? Thanks, I appreciate it.
Sample output should be:
Code is:Code is:Code:a = 3 b = 5 n = 5 3 3.5 4 4.5 5
Code:#include <iostream> using namespace std; void LineSpace(float a, float b, int n, float arrayOut[]); int main() { float a = 0.0f, b = 0.0f; int n = 0; cout << "Enter an interval [a,b] and number of nodal points n. " << endl; cout << "Input a = "; cin >> a; cout << "Input b = "; cin >> b; cout << "Input n = "; cin >> n; float* arrayOut = new float[n]; cout << a; LineSpace(a, b, n, arrayOut); cout << " " << b << endl; delete [] arrayOut; arrayOut = 0; } void LineSpace(float a, float b, int n, float* arrayOut) { int i = 0; float interval = 0.0f; for (i = 0; i < n - 2; ++i) { interval = (b - a)/(n - 1); //<-----formula was originally //(b-a)/ (n-2); I experimented with (n-1) and //it worked better.. not sure why?!? arrayOut[i] = a + interval; cout << " " << arrayOut[i] << " "; interval += interval; // <----- doesn't work... this is //supposed to add interval to itself each iteration } }
