Menghitung Usia
- Analisis :
Menghitung usia dimana masing masing tanggal dikonversi ke bilangan kemudian dihitung selisihnya.
- Tes Data
Misalnya :
Tanggal sekarang – tanggal lahir = 8 – 8 = 0 hari
Bulan sekarang – bulan lahir = 6 – 4 = 2 bulan
Tahun sekarang – tahun lahir = 2011 – 1992 = 19 tahun
Jadi, umur Aly sekarang adalah 19 tahun 2 bulan 0 hari
- Programnya :
#include <conio.h>
#include <iostream.h>
int main(){
int tgl_skrng,bln_skrng,thn_skrng,tgl_lahir,bln_lahir,thn_lahir,tahun,bulan1,
bulan2,tgl1,tgl2;
cout<<"masukan tanggal sekarang : ";
cin>>tgl_skrng;
cout<<"masukan bulan sekarang : ";
cin>>bln_skrng;
cout<<"masukan tahun sekarang : ";
cin>>thn_skrng;
cout<<endl;
cout<<"masukan tanggal lahir anda: ";
cin>>tgl_lahir;
cout<<"masukan bulan lahir anda : ";
cin>>bln_lahir;
cout<<"masukan tahun lahir anda : ";
cin>>thn_lahir;
cout<<endl;
tahun=thn_skrng-thn_lahir;
bulan1=bln_skrng-bln_lahir;
bulan2=bln_lahir-bln_skrng;
tgl1=tgl_skrng-tgl_lahir;
tgl2=tgl_lahir-tgl_skrng;
{
if((thn_skrng>thn_lahir)&&(tgl_skrng>=tgl_lahir)&&(bln_skrng>=bln_lahir))
{
cout<<"Umur anda: "<<tahun<<" tahun "<<bulan1<< " bulan "<<tgl1<< " hari "<<endl;
}
else if((thn_skrng>thn_lahir)&&(tgl_lahir>=tgl_skrng)&&(bln_lahir>=bln_skrng))
{
cout<<"Umur anda: "<<tahun<< " tahun "<<bulan2<< " bulan " <<tgl2<< " hari "<<endl;
}
else if((thn_skrng>thn_lahir)&&(tgl_skrng>=tgl_lahir)&&(bln_lahir>=bln_skrng))
{
cout<<"Umur anda: "<<tahun<<" tahun "<<bulan2<<" bulan "<<tgl1<<" hari "<<endl;
}
else if((thn_skrng>thn_lahir)&&(tgl_lahir>=tgl_skrng)&&(bln_skrng>=bln_lahir))
{
cout<<"Umur anda: "<<tahun<<" tahun "<<bulan1<<" bulan "<<tgl2<<" hari "<<endl;
}
else
{
cout<<"data yang anda masukan salah"<<endl;
}
}
getch();
}
Selisih Dua Waktu
Analisis :
Mencari selisih dua waktu yang waktu akhir dan awal dikonversikan menjadi detik dan kemudian dihitung selisihnya sehingga menghasilkan selisih waktu.
- Programnya :
#include<iostream.h>
#include<conio.h>
main(){
int j1,m1,d1,j2,m2,d2,d3,d5,w,x,y,z;
cout<<"Masukkan Waktu 1 :"<<endl;
cout<<"Jam = "; cin>>j1;
cout<<"Menit = "; cin>>m1;
cout<<"Detik = "; cin>>d1;
d3=(j1*3600)+(m1*60)+d1;
cout<<"Konversi Waktu 1 ke Detik : "<<d3;
cout<<" "<<endl; cout<<" "<<endl;
cout<<"Masukkan Waktu 2 :"<<endl;
cout<<"Jam = "; cin>>j2;
cout<<"Menit = "; cin>>m2;
cout<<"Detik = "; cin>>d2;
d5=(j2*3600)+(m2*60)+d2;
cout<<"Konversi Waktu 2 ke Detik : "<<d5;
cout<<" "<<endl; cout<<" "<<endl;
d5=d3-d5;
cout<<"Selisih Detik 1 dengan Detik 2 : "<<d5;
cout<<" "<<endl; cout<<" "<<endl;
cout<<"Konversi Selisih ke Waktu :"<<endl;
w=d5/3600;
x=d5%3600;
y=x/60;
z=x%60;
cout<<"Jam = "<<w<<endl;
cout<<"Menit = "<<y<<endl;
cout<<"Detik = "<<z<<endl;
getch();
}
ALGORITMA DAN PROGRAM MENCARI JARAK 2 TITIK
1. Analisis
Mencari jarak dua titik pada sebuah koordinat yang inputannya x1, x2, y1, y2
2. Identifikasi
Input : koordinat A(x1,y1) dan B(x2,y2)
Output : jarak
3. Algoritma
Deklarasi :
x1,x2,y1,y2,a,b : int
jarak : float
Deskripsi :
Baca x1;
Baca x2;
Baca y1;
Baca y2;
jarak=(sqrt(((x2-x1)*(x2-x1))+((y2-y1)*(y2-y1))));
End (Tulis jarak)
4. Program

Record (Rekaman)
Compiled by one or more fields. Each field stores data from certain basic types or from other types of formations that have been defined previously. The name of the recording is determined by the programmer.
