Program C++ Kalkulator

Algoritma kalkulator ()

Deklarasi:

a,b,c : float {  input }

   hasil,hasil1 : float { output }

Deskripsi:

Read(a,b,c)

hasil=tambah <= a+b

   hasil=kurang <= a-b

   hasil=kali <= a x b

   hasil=bagi <= a / b

hasil=per x <= 1 / a

hasil=pangkat *<= a

hasil=akar <= sqrt(a)

hasil=kuadrat <= a x a

hasil=kubik <= a x a x a

hasil=faktorial <= fak*i

   hasil1=sines <= sin(c)

   hasil1=cosines <= cos(c)

      hasil1=tangen <= tan(c)

   Write (hasil)

Berikut programnya :

#include <iostream.h>

#include <conio.h>

#include <math.h>

#include <stdio.h>

class kalkulator {

friend istream& operator >> (istream&, kalkulator&);

friend ostream& operator << (ostream&, const kalkulator&);
