On this new label,,, I specialize to describe the issues contained in the textbook.
in each chapter, I take one issue, I identified the problem, and then create a flowchart outlining the program.
for the program I'm using dev c + + created by overloading.




for this first article, I will discuss about the first meeting (sequence).
to the material I took from the dictates of algorithms and programming.

Analysis of the problem :

• determine the input: alas, tinggi
•  determine data type : int a, int t, float luas;
• the process of calculate the area : luas = a*t/2

  
flowchart and a program to calculate the area of ​​a triangle

 #include <cstdlib>
#include <iostream>

using namespace std;
class segitiga {
      friend istream& operator>>(istream&, segitiga&);
      friend ostream& operator<<(ostream&, segitiga&);


public :
       void hasil(){
            luas = a*t/2;
            }
private :
        int a,t;
        float luas;
};
istream& operator>>(istream& in, segitiga& datar){
         cout<<"Menghitung luas segitiga"<<endl;
         cout<<"masukkan alas = ";
         in>>datar.a;
         cout<<"masukkan tinggi = ";
         in>>datar.t;
         return in;
         }
       
ostream& operator<<(ostream& out, segitiga& bangun){
         bangun.hasil();
         out<<"luas segitiga = "<<bangun.luas<<endl;
         return out;
         }
       
int main()
{
    segitiga A;
    cin>>A;
    cout<<A;
    system("PAUSE");
    return 0;
}
