206_C113 Example  Problem Statement Compute the straight-line distance between two points in a plane  Input/Output Description Point 1 (x1, y1) Point 2 (x2, y2) Distance (d)

206_C114 Example  Hand Example p1 = (1, 3) p2 = (4, 7)  Algorithm Development (outline) Give values to the two points Compute lengths of two sides of right triangle Compute distance between points (hypotenuse) Print distance between points

206_C115 C++ Program /* */ /* Program chapter1_1 */ /* */ /* This program computes the distance between */ /* two points */ #include using namespace std;

206_C116 C++ Program int main() { // Declare and initialize objects double x1(1), y1(3), x2(4), y2(7), side1, side2, distance; // Compute sides of right triangle side1 = x2 - x1; side2 = y2 - y1; distance = sqrt(side1 * side1 + side2 * side2);

206_C117 C++ Program // Print distance cout << "The distance between the two points is " << distance << endl; // Windows friendly exit system("PAUSE"); return 0; } /* */
