Ok, I have to write a function called distance that will calculate the distance between 2 points in an x-y coordinate system. Each point will be specified by 2 double values. Also, this function will not contain any input/output code (i.e. no printf or scanf function calls).
Write a complete program that will test your function.
How am I supposed to test my results, if I can't have no input/output code? Please help me.
This is my code, but I haven't finished it yet, because I don't know what to do after that. Please help.
using namespace std;
double distance(double xOne, double yOne, double xTwo, double yTwo)
double xS, yS, result;
xS= xTwo - xOne;
xS= xS*xS; // value of x squared under radical
yS = yTwo - yOne;
yS = yS*yS; //value of y squared under radical
result = sqrt(xS + yS);
