I don't think that's necessary. Wouldn't it make more sense to let the computer guess and each try you say if the number is higher or lower? If two humans played the game together it would seem odd to me if the first step is telling the other one the number he has to guess...
- Output welcome message, and ask user to *think of* a number.- Decide on an initial guess.- Repeat: - Increment count of guesses. - Output the current guess and ask the user to indicate if it is high, low or correct. - If guess was correct, we're done and can break out of this loop. - Otherwise, modify the current guess (and loop again).- Output the count of guesses and terminate.Quote:

i don't know if this is what is causing your error or not, but you really should have a return 0; at the very end of the int main() function.
vc++ 6 is just giving me a warning about it, but other compilers might not allow it.

Can anyone figure out what's wrong with this program? Closes immediately after user enters "theNumber".
I tried using system("pause") where i have "cout << "\n\nPress Enter to see the Computer's guess...";" but the program would just get to that new pause point and close afterward (not much further than the previous closing @ entering 'theNumber').
-----------------------------------------
// Guess My Number 2.0
// Have computer guess your number
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int main()
{
int theNumber;
int tries;
cout << "\tWelcome to Guess My Number 2.0!\n\n";
cout << "Please enter a number to be guessed: ";
cin >> theNumber;
do
{
int comGuess = rand() % 100 + 1; //Problem 2
cout << "\n\nPress Enter to see the Computer's guess...";
getch();
cout << "The Computer's Guess: " << comGuess << ".\n";
++tries;
if (comGuess > theNumber) {
cout << "Too high!\n\n"; } //Not a problem, but its bad style
if (comGuess < theNumber) {
cout << "Too low!\n\n"; } //Same
} while (comGuess != theNumber); //Problem 1
cout << "\nThat's it! The Computer got it in " << tries << " guesses!\n";
getch();
}

Also, note that after the computer gets it it quits.
Also note: I'm not that skilled at C++ yet i picked up all the errors in ~10 seconds.

is there actually any c++ in that? i only see c statements. but i don't know c lol.
#include <iostream>using namespace std;int guess;int numTries = 0;bool correct = false;int input;int GuessMin = 0, GuessMax = 100;int GetRandomNum(int min, int max){ return min + int((max-min) * rand()/(RAND_MAX+1.0));}int main(){ srand(0); //could pass in current time here cout << "====Guess YOUR number====" << endl << endl; cout << "pick a number between 0 and 100, press any key when ready.." << endl; cin.get(); do { guess = GetRandomNum(GuessMin,GuessMax); cout << "is it " << guess << "??" << endl; cout << "enter 1 if too low, 2 if too high, 3 if correct" << endl; cin >> input; if (input == 1) { GuessMin = guess + 1; } else if (input == 2) { GuessMax = guess - 1; } else if (input == 3) { correct = true; } else { cout << "I don't understand " << input << endl; cout << "guessing again" << endl; } numTries++; } while(!correct); cout << "yes! I got it! phew..... took me " << numTries << " guesses!" << endl; cin.get(); return 0;}#include <iostream>using namespace std;int main(int ,char **){ double n; cout << "Give me your number: " << flush; cin >> n; if (!cin) { cerr << "You cheat!\n"; return 1;}; for(;;) { cout << "Was your number " << n << "? " << flush; string s; cin >> s; if (s=="y" || s=="yes") { cout << "I'm psychic!"; break; }; if (s=="n" || s=="no") { cout << "Liar!\n"; break; }; cout << "Answer yes or no. "; }}Quote:

I did probably the most ghetto/lazy way of writing this program that anyone has ever done.
However if this were actual homework the wording of the question yeilds my answer "bool" no matter how bad it is!!
