Contoh Beberapa Program Sederhana C++

Cara menggabungkan kalimat :

#include<iostream.h>

#include<string.h>

void main()

{

                char k1[50], k2[50];

                int p, p1, p2;

                cout<<"Kalimat 1    : ";

                cin.getline(k1,50);

                cout<<"Kalimat 2    : ";

                cin.getline(k2,50);

                cout<<endl;

                cout<<"Di Gabung    : "<<strcat(k1,k2)<<endl;

                p1=strlen(k1);

                p2=strlen(k2);

}

Output :

 

Pointer

// my first pointer

#include <iostream>

using namespace std;

int main ()

{

  int firstvalue, secondvalue;

  int * mypointer;

  mypointer = &firstvalue;

  *mypointer = 10;

  mypointer = &secondvalue;

  *mypointer = 20;

  cout << "firstvalue is " << firstvalue << endl;

  cout << "secondvalue is " << secondvalue << endl;

  return 0;

}

Output :
