[RESOLVED] Two issues

[celtik]

OK, I am having two issues right now. In the first program, I am trying to calculate the distance between two points. I think I have the right formula, but I am not sure. I am supposed to use the pow and sqrt functions, and I have tried. The output is something crazy.

#include <iostream>
#include <iomanip>
#include <cmath>

using namespace std;

int main()
{
    int x1;
    int x2;
    int y1;
    int y2;
    int d1;
    int d2;
    int d3;
    double distance;
    
    cout << "What is the x value for point 1?" << endl;
    cin >> x1;
    
    cout << "What is the y value for point 1?" << endl;
    cin >> y1;
    
    cout << "What is the x value for point 2?" << endl;
    cin >> x2;
    
    cout << "What is the y value for point 2?" << endl;
    cin >> y2;
    
    distance = sqrt(sqrt(x2-x1) + sqrt(y2-y1));
    
    cout << distance << endl;
    
    
system("pause");
return 0;

}

As for my 2nd problem, I am having issues with if else statements. I am supposed to be making an error handler for an invalid rating( not equal to 1, 2 or 3)...I have tried to do so but I guess I am just not getting it. I am new to C++ as you can see. Please help in anyway possible:

#include <iostream>
#include <iomanip>
using namespace std;

int main()
{ 
  double currentSalary ;            //input by user
  double raise ;                     //calculated by program based on the rating
  double newSalary ;                 // calculated by the program;currentSalary + raise 
  int rating ;                      // input by the user 
  string employee ;                 // the name of the employee
  
  
  // initialize raise and newSalary
  
  raise =0;
  newSalary = 0;
  
  cout << " Enter the employee's name and press enter   " ;
  getline ( cin, employee);
  
  cout << "Enter the current salary \t" ;
  cin >> currentSalary;

  cout << "Input a performance rating \n "
          "\t1 excellent \n\t2 good \n\t3 poor\n";
  cin >> rating ;
     
  if (rating = 1)
  
            newSalary = .06 * currentSalary;
            cout << "New Salary: " << currentSalary << endl;
            cout << "Raise Amount: 6%"  << endl;
            cout << "New Salary: " << newSalary << endl;
  
  if (rating = 2)
  
  
            newSalary = .04 * currentSalary;
            cout << "New Salary: " << currentSalary << endl;
            cout << "Raise Amount: 4%"  << endl;
            cout << "New Salary: " << newSalary << endl;
  
  if (rating = 3)
  
  
            newSalary = .015 * currentSalary;
            cout << "New Salary: " << currentSalary << endl;
            cout << "Raise Amount: 1.5%"  << endl;
            cout << "New Salary: " << newSalary << endl;
   
   if (rating != 1,2,3)
     cout << "Invalid rating" << endl;


            
  
  
  // Include if (if else) to calculate the raise and the new salary. 
  
  
  
  

  //cout << fixed << showpoint<<setprecision(2);
  //cout << "\n\nEmployee name: " << employee ;
  //cout << "\ncurrent salary\t$"<< currentSalary;
  //cout << "\nraise \t$"<< raise <<" for performance rating " << rating ; 
  //cout << "\nnew salary\t$"<< newSalary << "\n\n\n";

  system("pause");
}

[printf]

you can't write if statements this way unless there is only one line following the statement that you want to be executed

//WRONG
if (rating = 1)
  
            newSalary = .06 * currentSalary;
            cout << "New Salary: " << currentSalary << endl;
            cout << "Raise Amount: 6%"  << endl;
            cout << "New Salary: " << newSalary << endl;

//RIGHT
if (rating == 1){
  
            newSalary = .06 * currentSalary;
            cout << "New Salary: " << currentSalary << endl;
            cout << "Raise Amount: 6%"  << endl;
            cout << "New Salary: " << newSalary << endl;
}

//ALSO RIGHT
if (rating == 1)  
            cout << "New Salary: " << newSalary << endl;

//AND USE THIS FORM FOR IF/ELSE
if (rating == 1){
   //..
}else if (rating == 2){
   //..
}else if(...){
   //..
}

also notice you're conditional was incorrect 'rating=1' sets rating to 1, you need '=='. there may be other errors that i'm missing, but that's a start

Ah, thanks a lot..I didn't even notice those. I got the rating part working, just working on the distance one now

[wossname]

distance = sqrt(pow(x2-x1, 2) + pow(y2-y1, 2))

Edited - sorry I put in too many close parentheses.

[celtik]

I seem to be getting an error. "No matching function for call to pow(int). I think it may have something to do with the ", 2" but I am not sure.

[wossname]

My fault, see my above post again, I've edited it a bit.

[celtik]

I think I got it. Thanks
