c++ programing

I have the code so i need you to check them 🙂 and put them in one program

part A is in a file.

part B is this :

#include

#include //header files

using namespace std;

//global vairables declare

int var_x_1, var_x_2, var_x_3, var_y_1, var_y_2, var_y_3, centreX, centreY;

double radius;

//function declaration

void get3points()

;

void

calucateCenterPoints();

void

calucateRadiusValue();

void

outputInfo();

int main() //start main function

{

get3points(); // function calling

calucateCenterPoints(); calucateRadiusValue(); outputInfo();

return 0;

}

//end of main function

void get3points(){

cout<<"First co-ordinates :-"<

cin>>var_x_1>>var_y_1;

cout<<"Second co-ordinates :-"<

cin>>var_x_2>>var_y_2;

cout<<"Third co-ordinates :-"<

cin>>var_x_3>>var_y_3;

}

void calucateCenterPoints()

{

//calculation for finding ‘x’ co-ordinates of center

centreX = -1 * ((( var_x_3*var_x_3 – var_x_2*var_x_2 + var_y_3*var_y_3 – var_y_2*var_y_2)/(2*(var_y_3-var_y_2)) ) -((var_x_2*var_x_2 – var_x_1*var_x_1 + var_y_2*var_y_2 – var_y_1*var_y_1)/(2 *(var_y_2-var_y_1)))) /((var_x_2-var_x_1)/(var_y_2-var_y_1))-((var_x_3-var_x_2)/(var_y_3-var_y_2));

//calculation for finding ‘y’ co-ordiunates of center

centreY = (-1 * centreX*((var_x_2-var_x_1)/(var_y_2-var_y_1))) +( (var_x_2*var_x_2 – var_x_1*var_x_1 + var_y_2*var_y_2 -var_y_1*var_y_1)/ (2 * (var_y_2-var_y_1)) );

}

void calucateRadiusValue()

{

//calculateion for radius of circle

radius = sqrt( pow(centreX-var_x_1, 2)+ pow(centreY-var_y_1, 2));

}

void outputInfo()

{

//print the info on the console

cout<<"Centre is "<

cout<<"Radius is "<
