Assignment I am having trouble with:
Complete 'this program', by adding a function called mag( ) to calculate the magnitude of a vector. You'll need to add a prototype before main( ), and the implementation (header & body) of the function after main( );
reminder: mag = sqrt (x^2 + y^2)
Calling it with something like:
vec_length = mag(x, y);
program to be completed:
#include<iostream>
#include<cmath>
using namespace std;
// for part a, put your function prototype for mag here!
//............................................................
int main(void)
{
double x = 0;
double y = 0;
double v=3.0, w=4.0;
double m;
cout << "Please enter the X coordinate: ";
cin >> x;
cout << "Please enter the Y coordinate: ";
cin >> y;
m = mag(x,y); // you need to write this function!
cout << "The magnitude of ( "<< x << " , "<< y <<" ) is: " << m << endl;
m = mag(v,w); // now get the magnitude of vector (v,w)
cout << "The magnitude of ( "<< v << " , "<< w <<" ) is: " << m << endl;
return 0;
}
//.................put your mag function here...................
// be sure to add comments describing the inputs and outputs so a reader would
// know how to use it.
