//Description: This program takes in measurements in inches that are input by the user
//             the program then runs through three functions that output to the screen the
//             conversions to meters and yards

#include <iostream>

void description();//description
void getInfo (int a[], int& num);//get input
void displayInches (int a[], int num);//displays inches
void displayMeters (int a[], int num, double& meters);//displays meters
void displayYards (int a[], int num, double& yards);//displays yards
