Need help

[bobat18]

Hey everyone, this is my first post, and i was wondering if you could lend a hand with a problem i'am having with a class project. Im stuck on what to do. Any help would be greatly appreceited.

here is the project guidelines:

Description :
Write a program to read in a set of integer starting coordinates. Then read in a series of "directional moves". Each directional move is made up of a single character followed by a real number. The char is N, S, W, or E to indicate direction and the real number is how far to "move". When the user enters a 'q' for a direction the program will then print out the final location. (Do not allow further input)

Input :
First, a set of integers representing a starting location (X, Y). Then a series of directional moves as described above until a 'q' is entered. Case does not matter to the user.

Output :
Output is the final (X,Y) coordinates up to 2 decimal places. Account for the spaces as show in the sample run.

Sample Run :
Here is a sample execution:

% ./project2

Welcome to Project #1 : You Sunk My Battleship!

Enter starting (X, Y) coordinates : 12 5

Enter Move : N 5.0
Enter Move : S 3.3
Enter Move : E 13.3
Enter Move : W -2.33
Enter Move : Q

The final position is ( 27.63, 6.70 ).

%

Here is another sample run, more complicated:

% ./project2

Welcome to Project #1 : You Sunk My Battleship!

Enter starting (X, Y) coordinates : 12 5

Enter Move : N 3.4
Enter Move : S -2.6
Enter Move : E 5
Enter Move : w 9
Enter Move : w -3.2
Enter Move : w 0.1
Enter Move : e -0.33
Enter Move : n 5.12
Enter Move : s -3.141592654
Enter Move : q

The final position is ( 10.77, 19.26 ).

Here is ths actual code i have thus far. I' am very new to coding and any help would be greatly appreceited.

/////////////////////////////////////////////

#include <iostream>
void main () {

int x,y;
char dir;


cout << "Enter strating Coordinates (X, Y) :";
cin >> x, >> y;
do {
cout << "Enter Move :";
cin >> dir;
} while (dir !='q');
}

///////////////////////////////////////////////////
I know it is very raw, but i have no clue what to do from here. thank you again. If you have a better idea to write this code, please let me know and show.
Thanks

Has your class studied functions, yet? At any rate, after you get the starting coords maybe you could store them in float variables called X and Y.

Each time you loop though the input, you should take in a char and use a switch statement. If the char is q, cout << X, Y, or if it is a direction (N,E,S,W) read a float.

The direction itself will tell you what to do with the float. N for example means you should add that float to Y, whereas W, would mean subtract it from X.

Does that outline help enough that you could write the code now?

not really, think you could write up an example. sorry bro, i just dont get it yet.

[teknomage1]

If I write up an example I've done your work for you, "bro." Why don't you write a bit more and post how much farther you've gotten.

Study this code closely then

#include <iostream>

int main()
{
  double x=0.0,y=0.0, incr=0.0;
  char move;
  std::cout << "Enter starting Coordinates (X, Y) : ";
  std::cout.flush();
  std::cin >> x >> y;
  std::cin.ignore(); /* discard the '\n' in stdin stream */
  while(move != 'q' && move != 'Q')
    {
      std::cout << "Enter Move : ";
      std::cout.flush();
      std::cin >> move;
      if(move == 'q' || move == 'Q')
	break;/* we gotta go */
      std::cin >> incr;
      std::cin.ignore();
      switch(move)
	{
	case 'n':
	case 'N':
	  /* move north, increase y */
	  break;
	case 'e':
	case 'E':
	  /* move east, increase x */
	  break;
	case 's':
	case 'S':
	  /* move south, decrease y */
	  break;
	case 'w':
	case 'W':
	  /* move west, decrease x */
	  break;
	default:
	  std::cout << "The chosen move (" << move 
		    << ") is unsupported" << std::endl;
	  break;
	}
    }
  std::cout <<"The final position is ("; 
  std::cout << x << ", " ;
  std::cout << y << ")" << std::endl;
  return 0;
}
