1. Random Number Generation

2. Pseudo-Random Generation

3. rand()
#include <iostream> using namespace std; int main() { for(int i = 1; i <= 10; i++) cout << rand() << endl; return 0; }

4. rand()
First Execution
#include <iostream> using namespace std; int main() { for(int i = 1; i <= 10; i++) cout << rand() << endl; return 0; }

5. rand()
First Execution
Second Execution
#include <iostream> using namespace std; int main() { for(int i = 1; i <= 10; i++) cout << rand() << endl; return 0; }

6. srand()
#include <iostream> #include <ctime> #include <cstdlib> using namespace std; int main() { srand(time(NULL)); for(int i = 1; i <= 10; i++) cout << rand() << endl; return 0; }

7. srand()
First Execution
#include <iostream> #include <ctime> #include <cstdlib> using namespace std; int main() { srand(time(NULL)); for(int i = 1; i <= 10; i++) cout << rand() << endl; return 0; }

8. srand()
First Execution
Second Execution
#include <iostream> #include <ctime> #include <cstdlib> using namespace std; int main() { srand(time(NULL)); for(int i = 1; i <= 10; i++) cout << rand() << endl; return 0; }

9. limiting range: [0, MAX_RAND]
#include <iostream> #include <ctime> #include <cstdlib> using namespace std; int main() { long next_value; srand(time(NULL)); for (int i = 1; i <= ; i++) if (rand()%100 <= 34) cout << "hello" << endl; // ~35,000 times else cout << "goodbye" << endl; // ~65,000 times return 0; }
