Thread: WHAT is going ON!?

Okay, i'm getting this really odd error message...26 times.

The message is:

Error E2206 1: Illegal character ' ' (0x0)

My code to classify a triangle.

Code:

#include <iostream>
#include <cstdlib>
#include <cmath>

using namespace std;

int main()
{
	int co1x;
	int co1y;
	int co2x;
	int co2y;
	int co3x;
	int co3y;
	int dis1;
	int dis2;
	int dis3;

	cout<<"Enter the coordinates of the triangle" << endl;
	cout<<"X coordinate of point 1: " << flush;
	cin.ignore();
	cin>>co1x;
	cout<<"Y coordinate of point 1: "<< flush;
	cin.ignore();
	cin>>co1y;
	cout<<"X coordinate of point 2: "<< flush;
	cin.ignore();
	cin>>co2x;
	cout<<"Y coordinate of point 2: "<< flush;
	cin.ignore();
	cin>>co2y;
	cout<<"X coordinate of point 3: "<< flush;
	cin.ignore();
	cin>>co3x;
	cout<<"Y coordinate of point 3: "<< flush;
	cin.ignore();
	cin>> co3y;

	sqrt((co1x - co2x)^2 + (co1y - co2y)^2) = dis1;
	sqrt((co2x - co3x)^2 + (co2y - co3y)^2) = dis2;
	sqrt((co3x - co1x)^2 + (co3y - co1y)^2) = dis3;

	if (dis1 == dis2 && dis2 == dis3 && dis3 == dis1)
	cout<<"The triangle is equilateral." << endl;
	
	else if (dis1 == dis2 && dis2 == dis1)
	cout<<"The triangle is isoceles." << endl;
	
	else if (dis2 == dis3 && dis3 == dis2)
	cout<<"The triangle is isoceles." << endl;

	else if (dis3 == dis1 && dis1 == dis3)
	cout<<"The triangle is isoceles." << endl;

	else if (dis3 != dis1 && dis2 != dis1 && dis2 != dis3)
	cout<<"The triangle is scalene." <<endl;
	
	cin.get();
}

What is going on!?

0x0 is a hexadecimal character I think.

You're sure ^ is a legal C++ character?

Code:

	radical((co1x - co2x)^2 + (co1y - co2y)^2) = dis1
	radical((co2x - co3x)^2 + (co2y - co3y)^2) = dis2 
	radical((co3x - co1x)^2 + (co3y - co1y)^2) = dis3

Even if this made sense you're missing semicolons at the end of each of these lines. Now why are you trying to set a character with magic argument equal to an integer? If there is a function definition you aren't showing us, then post it.

Ofcourse it doesn't those lines make no sense. You can't assign a character to an integer and expect the radical to be there. Besides, it looks like what you're trying to do is get the square root. You don't do that by adding a radical character to a number.

Add <cmath> and use the sqrt() function.

Why don't use actually find out how to use sqrt() before you just throw it into your program.

Secondly. You're assigning the return TO A VARIABLE. Not a variable to the function return. disN should be on the left.

Download Dev-C++ and use it. It's magical and it makes money grow on trees.

It is, but it does bitwise XOR, not exponentiation.
