Mind that this is my first actual program in C++ and I tried to prepare for any possible input. Also the reason I included static_cast<void>(generator(range)) is to throw away the first random value because I read on LearnCpp.com that throwing away the first is a common practice to produce more random results. Anyways here is the code, all suggestions are welcome.
#include <iostream>
#include <limits>
#include <random>
bool validateInput(int input)
{
using namespace std;
if (1 <= input && input <= 100)
return true;
else if (!input)
return false;
else
return false;
}
int generateRandomNumber()
{
std::random_device dev;
std::mt19937_64 range(dev());
std::uniform_int_distribution<std::mt19937_64::result_type> generator(1, 100);
static_cast<void>(generator(range));
return static_cast<int>(generator(range));
}
bool placement(int input, int target)
{
using namespace std;
if (input > target)
{
cout << "Guess is too high.";
return false;
}
else if (input < target)
{
cout << "Guess is too low.";
return false;
}
else
{
cout << "Guess is correct!";
return true;
}
}
int main()
{
using namespace std;
cout << "You have 7 guesses to guess what number I am thinking of between 1 and 100.\n";
int winning_num{ generateRandomNumber() };
static int tries{ 1 };
do
{
int num;
cout << "\nGuess#" << tries << ": Enter a number -> ";
cin >> num;
if (!cin)
{
cin.clear();
cin.ignore(numeric_limits<streamsize>::max(), '\n');
continue;
}
cin.ignore(numeric_limits<streamsize>::max(), '\n');
if (validateInput(num))
;
else
{
continue;
}
if (!placement(num, winning_num))
{
cout << "\nIncorrect!\n";
++tries;
}
else
{
cout << "\nCorrect!\n";
exit(0);
}
}
while (tries <= 7);
cout << "\nYou did not guess the number in the alloted amount of guesses :(\nTry Again!\n";
}
