Day 22 - Intro to C++

HOMEWORK:
Hand Recognition:
#include <iostream>
#include <cmath>
using namespace std;
int main(void)
{
//Declare and initialize variables.
double unknown[5]={5.4,7.2,7.9,7.4,5.1},
known[5]={6.2,7.0,8.0,7.4,5.8};
double distance(double hand_1[5],double hand_2[5]);
// Compute and print distance.
cout << "Distance: " << distance(unknown,known) << endl;
// Exit program.
system("PAUSE");
return 0;
}
//-----------------------------------------------------------------
// This function computes the distance between two hand measurements.
double distance(double hand_1[5],double hand_2[5])
{
// Declare variables.
int k;
double sum=0;
// Compute sum of absolute value differences.
for (k=0; k<=4; k++)
sum = sum + fabs(hand_1[k]-hand_2[k]);
// Return distance value.
return sum;
