I'm going through my C++ book and have currently made a working Guess The Number game.
The game generates a random number based on current time, has the user input their guess, and then tells them whether it was too high, too low, or the correct number.
The game functions fine if you enter a number, but returns 'Too High' if you enter something that is not a number (such as a letter or punctuation). Not only does it return 'too high', but it also continually returns it.
I was wondering what I could do to check if the guess, as input by the user, is an integer and if it is not, to return 'Not a number. Guess again.'
Here is the code.
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int main()
{
srand(time(0)); // seed the random number generator
int theNumber = rand() % 100 + 1; // random number between 1 and 100
int tries = 0, guess;
cout << "\tWelcome to Guess My Number!\n\n";
do
{
cout << "Enter a guess: ";
cin >> guess;
++tries;
if (guess > theNumber)
cout << "Too high!\n\n";
if (guess < theNumber)
cout << "Too low!\n\n";
} while (guess != theNumber);
cout << "\nThat's it! You got it in " << tries << " guesses!\n";
cout << "\nPress Enter to exit.\n";
cin.ignore(cin.rdbuf()->in_avail() + 1);
return 0;
}
