rasing variable to 2nd power

[Flash41000]

Say you have variables A B C, that the user puts in a side of a triangle. Obviously I am attempting to make a program that checks to see if a²+b²=c² is true. The question is, how do I raise the variable to the second power?
Im using Dev C++

You do know what that means, right?

int a = 10;
int a_squared = a * a;

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

using namespace std;

void Start;
void GetResults();

char a, b, c;

void
Start()
{
       while((a * a) + (b * b) != (c * c))
       {
                
                cout << "Please put in line A\n";
                a = 0;
                cin >> a;
                
                cout << "please put in line B\n";
                b = 0;
                cin >> b;
                
                cout << "please put in line C\n";
                c = 0;
                cin << c;
                
                                
                if((a * a) + (b * b) != (c * c))
                {
                      cout << "This is not a Right Triangle.\n";
                }
       }
       
       GetResults();

                if((a * a) + (b * b) == (c * c))
                {
                      cout << "This is a Right Triangle.\n";
                }
}

void 
GetResults();
{
  
             
}

int

main();
{
       a = 0;
       b = 0;
       c = 0;
       cout << "Finds Right Triangles!!!!!\n";
       Start();
       return 0;
}

This what i have so far but it wont compile, it comes with this message Circular main <-Main.o dependency dropped...
I dont even know if this would be remotely the right way to write this program

[seymore15074]

Start by removing the semicolon on lines 46 and 54.

You're doing fine with the program, it just needs a little refinement.

[Dacster13]

void Start;

this line should be

void Start();

[ozan]

There is something
c=0;
cin << c;
This should be
c=0;
cin >>c;

Thank you for The catches, but it didnt fix my problem. I dont know how to fix it!!!!

You need to make sure that variable c is the hypotenuse of the right triangle. (That's the longest side of the triangle.) To do this, make a variable called temp of the same type as a, b, and c. Then after you input a, b, and c, use code like this:

if (a > c) {
  temp = a;
  a = c;
  c = temp;
}
if (b > c) {
  temp = b;
  b = c;
  c = temp;
}

Also, you should use a do-while loop with this code, not a while loop.
