/*************************************************** Length of Vectors Write a program that reads in a vector in the form (x,y), and writes out the length of the vector. In high school math, a vector is usually a pair (x,y), where x and y are real numbers. The length or magnitude of a vector is _________ \/x^2 + y^2. ***************************************************/ #include <iostream> #include <cmath> using namespace std; int main() { // read pair char c; double x, y; cin >> c; // reads ( cin >> x; cin >> c; // reads , cin >> y; cin >> c; // reads ) // compute magnitude double m; m = sqrt(x*x + y*y); // write out result cout << "The magnitude is " << m << endl; return 0; }
