Question

Please help code in c++ and use the answers you get from question 1 and 2 into the 3rd answer! Question 1 is first, question 2 is in the middle, question 3 is last

Input Array (10 pts) te a function only (no main) that takes an array of doubles as a parameter as well as another integer rray. Create a for loop that asks the user to input any real number between-100 and r each element of the array. Use an input validation while loop to only allow them to enter numbers th at are within the range. Assign each input to an element of the array

Answer 1

Here is your code:

#include<iostream>
#include<cmath>
using namespace std;
double InputArray(double arr[],int size)    // function for question 1
   {  
       int i,input;
       for(i=0;i<size;i++)
       {
           std::cout<<"\nEnter a number :";
           std::cin>>input;
           while(1)
           {
               if(input>=-100 && input<=100)
               {
                   arr[i]=input;
                   break;      
               }  
               else
                   std::cout<<"\nPlease enter number in the given range -100 to 100 (inclusive) :";
                   std::cin>>input;  
           }  
       }      
   }
double Distance(double a[],double b[])   //function for question 2
{
   double d,k,l,m;
   k=pow((a[0]-b[0]),2); // calculates the power by 2
   l=pow((a[1]-b[1]),2);   // calculates the power by 2
   m=pow((a[2]-b[2]),2);   // calculates the power by 2
   d=sqrt((k+l+m));        //calculate squareroot.
   return d;
}
int main()   //answer for question 3
{
   char decision;
   double kvm,f;
   while(1)
   {
       double x[3],y[3];
       InputArray(x,3); //calling InputArray function
       InputArray(y,3); //calling InputArray function
       std::cout<<"\nWould you like to calculate the distance between two vectors (y/n):";  
       std::cin>>decision;
       if(decision=='y')
       {
           kvm=Distance(x,y); //calling decision function.
           std::cout<<"distance is:"<<kvm;  
           f=fabs(kvm);
           if(f>0.0001 && f<10.0)
               std::cout<<"\nTarget in range!";
       }
       else
           break;
   }  
}

Output:

Enter a number :1 Enter a number :2 Enter a number:-20e Please enter number in the given range -100 to 100 (inclusive) :3 Enter a number:4 Enter a number :3 Enter a number :300 Please enter number in the given range -100 to 100 (inclusive) :2 Would you like to calculate the distance between two vectors (y/n):y distance is:3.31662 Target in range! Enter a number :3 Enter a number:4 Enter a number :5 Enter a number:6 Enter a number :5 Enter a number:4 Would you like to calculate the distance between two vectors (y/n):rn Process exited normally.
