#include <iostream>
#include <conio.h>
using namespace std;

void nilai(int *a){
*a = 10;
}

int main(){
int a = 5;
cout << "Nilai awal :" << a << endl;
nilai(&a);
cout << "Nilai akhir:" << a << endl;
}

#include <iostream>
using namespace std;
long kuadrat(long l){
return l * l;
}
main(){
long bil;
cout << "Input sebuah bilangan : ";
cin >> bil;
cout << "Hasil kuadratnya = " <<
kuadrat(bil);
}
