rand into variable

[rampen123]

Hi,

I'm new here and just started learning C++. I'm trying to recreate "Hang Man" game using only #include <iostream> (and apparently #include <ctime> and #include <cstdlib>). I've created all the necessary code to launch it, but I don't know how to make the animal selection random. Can anyone tell me how? I'm sorry for not using English, but I will translate as best as I can when asked. Thanks.
#include <iostream>
using namespace std;


int main()
{
//Keywords
char nama[100];
int tipe;
char yn,ulang;
char b1='_';
char b2='_';
char b3='_';
char b4='_';
char b5='_';
char b6='_';
char b7='_';
char b8='_';
char a1;
char a2[]="ULAR";
char a3[]="GARUDA";
char a4[]="KOMODO";
float binatang;
int kesempatan;



//Restart
do
{
//Penyebutan Nama
cout << "\n\n\nSelamat datang di permainan Hang Man! \n\n\nMasukkan nama Anda: ";
cin >> nama;
cout << "\nSelamat datang " << nama << "! \n\n\n";

//Penentuan Mode
do
{
//Pemilihan Mode
do
{
cout << "Mode apa yang ingin anda mainkan? \n 1. Zen \n 2. Classic \n";
cin >> tipe;
} while(tipe<=0||tipe>=3);

//Peraturan dan Konfirmasi
do
{
switch (tipe)
{
case 1:{
cout << "Aturan permainannya adalah seperti ini: Anda memiliki kesempatan sebanyak 10 kali. Tidak ada bantuan. \n";
cout << "Apakah Anda ingin bermain Zen? Y/N: ";
cin >> yn;
cout << "\n\n";
} break;

case 2:{
cout << "Aturan permainannya adalah seperti ini: Anda memiliki kesempatan sebanyak 5 kali, tetapi Anda akan diberikan Hint pada awal dan setiap kesalahan yang Anda buat \n";
cout << "Apakah Anda ingin bermain Classic? Y/N: ";
cin >> yn;
cout << "\n\n";
} break;

Then focus on C++ rather than C. The <ctime> and <cstdlib> are C. C++ has <random> (and <chrono>).

char a1;
char a2[]="ULAR";

Any time you find yourself writing variables like this you should ask yourself if an array is more appropriate:

char b[8]{'_'};
const char *a[] = {"ULAR", "GARUDA", "KOMODO"};
