Question

WRITE AN INTERACTIVE PROGRAM

that allows the user to enter (at least two)....UP-TO 15 vectors that are to be added........display the resultant on the screen

study in your text the if statement

[use the if statement to make sure the user only enteres between two and 15 vectors] **Comments all the line

use <iostream>, <fstream>, <cmath>, <math.h> as a header file, do not use any other

one of my friend did it like below, i think all patterns are good here, but professor asked to use if statement  to make sure the user only enteres between two and 15 vectors...so need to fix it...

/*
Dweep Dey Program 6

This program add up to fifteen vectors from a text file
*/

using namespace std;

#include <iostream>
#include <cmath>
#include <math.h>

int main()
{
   float length, theta; //local variables
  
   cout<<"I wrote this to show the addition of vectors in a text file...''"<<endl; // user message
   getdata(); // calls getdata
   calcvector(length, theta); // calls calcvector

   system;"pause"; //so we can see the equation printed on the screen above
   return 0; // ends program
}
void getdata()
{
   int i, numberofdatas;
Infile.open("thedata.txt");

   }
   numberofdatas=i;
   cout<<"number of data points "<<numberofdatas<<endl; // shows # of data points in file
       Infile.close(); // closes file
       system;"pause";   
  
}
float calcvector(float len, float the) // starts calcvector

       int i=0; // local variables
       float valuex=0, valuey=0, valuexx=0, valueyy=0; // local variables
   //   len =length[i]; the = theta[i]; // sets arrays into usable format
      
   for(i=0; i<=(a-1); i++); //separate x value loop
   {
       len =length[i]; the = theta[i]; // sets arrays into usable format
       rdir=(3.14159/180.0)*the; // turns degress into radians
      
       valuex=valuex+cos(rdir)*len; // calculates x value
      
       cout<<"x="<<valuex<<endl; //shows user x value

   }
  
       cout<<"sum x="<<valuexx<<endl; // shows user sum of all x values

   {
       len =length[i]; the = theta[i]; // sets arrays into usable format
       valuey=sin(rdir)*len; // calculates y value
      
       cout<<"y="<<valuey<<endl; // shows user y values
      
       valueyy = valuey+valuey; // sum of y values
   }
       cout<<"sum y="<<valueyy<<endl; // shows user sum of all y values
  
      
       magnitude=((valuexx*valuexx)+(valueyy*valueyy)); //adding sum of x and y squared
      
       cout<<magnitude<<endl; // shows user value of x and y squared and added
      
       rlength=sqrt(magnitude); // finding root of the sums
      
       cout<<"magnitude is..."<<rlength<<endl; // displays magnitude
      
       resdir=atan(valuey/valuex); // finds angle of new vector
      
       endtheta=(180.0/3.14159)*resdir; // turns radians to degress
      
       cout<<"direction is..."<<endtheta; // displays final angle for user
      
       system;"pause";
      
   }

***We cannot use void get data under int main(), however he did its good

Thank you.
