Complex

[CATCH3624]

Hello. I need to print out the total (summation of all complex numbers) I retrieved from the complex.txt files and I'm having problems...Can someone help please...

#include <iostream> // Directive for iostrem library.
#include <fstream>

using namespace std; // namespace is a collection of identifiers in the standard library.

class Complex // Type Object
{                   
	double real;
	double img;
public:       // Constructors
	Complex(double a=0, double b=0); 
	void set_real(double a);
	void set_img(double b);
	double get_real();
	double get_img();
	void print();
	Complex plus(Complex c);
	Complex minus(Complex c);
	Complex mul(Complex c);
	Complex div(Complex c);
};  
Complex Complex::minus(Complex c) // Complex Operator
{
	Complex x;
	x.real = real - c.real;
	x.img = img - c.img;
	return x;
}
Complex Complex::mul(Complex c) // Complex Operator
{
	Complex x;
	x.real = real * c.real -img * c.img;
	x.img = img * c.real + real * c.img;
	return x;
}

	Complex x;
	double temp = c.real * c.real + c.img * c.img;
	x.real = (real * c.real + img * c.img) / temp;
	x.img = (img * c.real - real * c.img) / temp;
	return x;
}

	 cout << "This is what is inside of complex.txt: \n ";

	 char ch;

     while(fin.get(ch)) //reads characters from the file

            cout << ch; //prints characters to the screen
	fin.close(); //closes the file "complex.txt"
	cin >> num; // !!!This is where the program stop running!!!
 ptr = new Complex[num];
 for ( i = 0; i < num; i++)

	 cin>>a>>b;
	 ptr[i].set_real (a);
	 ptr[i].set_img (b);
	 total = total = total.plus (ptr[i]);
 }
 cout<<"The total is ";
 total.print();
 cout<<endl;
 return 0;
 }

line 64 is asking the user to enter value for num instead of getting num from file. try this:

I assumed you wanted to read the values for a and b from the file. on line 68 you are again asking the user to input these values. Below fixes that as well/

num=0;
while(fin.get(ch))
     ++num;
fin.clear();
fin.seekg(0);

ptr=new Complex[num];
for(i=0;i<count/2;++i)
{
     fin>>a>>b;
     ptr[i].set_real (a);
     ptr[i].set_img (b);
     total = total = total.plus (ptr[i]);
 }
