Script

Input Standart :                                                                           

#include<iostream.h>
#include<conio.h>

void main()
{
char nama[50];
char nim[10];

cout<<"masukan nama anda"<<endl;
cin.getline(nama,50);
cout<<"masukan nim anda"<<endl;
cin>>nim;
cout<<"nama saya : "<<nama<<endl;
cout<<"nim saya :  "<<nim<<endl;
getch();
}

Kalkulator :

#include<stdio.h>
#include<conio.h>
#include<iostream.h>

main()
{
int a,b,c=0;

printf("Masukan Nilai A = "); scanf ("%d",&a);
printf("Masukan Nilai B = "); scanf ("%d",&b);

c=a+b;
printf("Hasil Penjumlahan = %d",c);
cout<<endl;

printf("Masukan Nilai A = "); scanf ("%d",&a);
printf("Masukan Nilai B = "); scanf ("%d",&b);

c=a-b;
printf("Hasil Pengurangan = %d",c);
cout<<endl;

printf("Masukan Nilai A = "); scanf ("%d",&a);
printf("Masukan Nilai B = "); scanf ("%d",&b);

c=a*b;
printf("Hasil Perkalian = %d",c);
cout<<endl;

printf("Masukan Nilai B = "); scanf ("%d",&b);

c=a/b;
printf("Hasil Pembagian = %d",c);
cout<<endl;
