Contoh Program Kalkulator C++

#include <iostream>

using namespace std;

int main2 (){

int pilih; // deklarasi variabel

float bil1,bil2,hasil;

cout<<"####################################"<<endl;

cout<<"## APLIKASI KALKULATOR LP2M-ARAY ##"<<endl;

cout<<"## TONNY ##"<<endl;

cout<<"####################################"<<endl;

cout<<endl;

cout<<"Masukkan Bil1 :";

cin>>bil1;

cout<<"Masukkan Bil2 :";

cin>>bil2;

hasil=bil1+bil2;

cout<<endl;

cout<<"Hasil="<<hasil;

cin.get();

return 0;

}

Hasilnya

#include <iostream>

#include <string.h>

using namespace std;

int pangkat(int a, int b){

int hasil,i;

hasil=1;

for(i=1;i<=b;i++){

hasil= hasil * a;

}

return hasil;

}

int main2 (){

char *operators= "???";

int pilih;

float bil1,bil2,hasil;

cout<<"####################################"<<endl;

cout<<"## APLIKASI KALKULATOR LP2M-ARAY ##"<<endl;

cout<<"## HARI I-LAT 2 By TONNY ##"<<endl;

cout<<"####################################"<<endl;

cout<<"Masukkan Bil1 :";
