Program calculates the distance in a graph

Assalaikum my friend.....How are you...i hope you fine like me...

long is not a blog post. understand, many new tasks. Yes, although this blog post also includes the task.

well, now I'll post the program calculates the distance in a graph.

we just see the program !!!

#include <cstdlib>
#include <iostream.h>
#include <string.h>

using namespace std;

int main(int argc, char *argv[])
{
    char kata1;  //variabel
    char kata2;  //variabel
    char kata3;  //variabel
    int a, b, c;  // tdata type
   
    cout<<"||====================================================||"<<endl;
    cout<<"||          Program Menghitung Jarak pada Graf        ||"<<endl;
    cout<<"||====================================================||"<<endl;
    cout<<endl;
   
    cout<<"Masukkan jarak antara titik simpul "<<kata1<<" dengan "<<kata3<<" : ";cin>>a;
    cout<<"Masukkan jarak antara titik simpul "<<kata3<<" dengan "<<kata2<<" : ";cin>>b;
    cout<<"Masukkan jarak antara titik simpul "<<kata2<<" dengan "<<kata1<<" : ";cin>>c;
    cout<<endl<<endl;
    cout<<"Jadi panjang jarak pada graf totalnya = "<<a+b+c<<endl<<endl;  // formula to calculate the triangle graph
   
  
    system("color 57");  //gives color to the results of running
    system("PAUSE");
    return EXIT_SUCCESS;
}

explanation :

   

This program is made in Dev C++. Purpose of the program above is, calculate the distance on the graph, which suppose an image triangle A, B, C as below

The program may calculate the distance from A to B, B to C and B to C.
