Pertemuan keempat

Kali ini membahas Array

1. Array [Input & Output]

#include <iostream>
using namespace std;

class Arrq{
private:
int arr[9];
int i;
public:
void input(int i,int b){
if (i<b){
cout<<"Masukkan Array ";
cin>>arr[i];
input(i+1,b);

}

}
void output(int i,int b){


//for (int i=0;i<9;i++){
if (i<b){

cout<<arr[i]<<" ";
cout<<endl;
output(i+1,b);
}


}
};



int main(int argc, char *argv[]) {
Arrq a;
a.input(0,9);
cout<<endl;
a.output(0,9);


return 0;

}


2. Array [Mengubah baris menjadi kolom]

#include <iostream>
using namespace std;

int main(int argc, char *argv[]) {
int arr[9]={1,2,3,4,5,6,7,8,9,};
int p=0;
cout<<"sebelum di tukar= \n";

for(int b=0;b<3;b++){
for(int h=0;h<3;h++){
cout<<arr[h+p]<<" ";

}cout<<endl;
p=p+3;
}
int q=0;
for (int c=0;c<9;c++){
if (arr [c]%3!=0){
int temp=arr[c];
arr[c]=arr[c+1];
arr[c+1]=temp;

}
}
cout<<"setelah di tukar = \n";
cout<<endl;
for(int i=0;i<3;i++){
for (int a=0;a<3;a++){
cout<<arr[a+q]<<" ";

}cout<<endl;
q=q+3;

}
return 0;

}
