Ugh, this is almost embarassing, first time posting source code. ._.

I have an error with a program I constructed. It compiles fine, I just can't seem to locate the problem. The program is suppose to continue to guess random numbers and compare it to a number that the user inputted and continue until it guesses it... Buuut it stops after the first try. ;.;

Quote:

// Guess My Number, Round 2
// A White-Hat` Production

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;

int main()
{
srand(time(0)); // seed the random number generator

int tries = 0, theNumber;
int theGuesser = rand() % 100 + 1; // random number between 1 and 100
cout << "\tWelcome to the Guess My Number game; White-hat` edition!\n\n";

do
{
cout << "Please enter your number, so the computer may guess it: ";
cin >> theNumber;

cout << "Test run: " << theGuesser << "\n";
++tries;

if (theGuesser != theNumber) {
theGuesser = rand() % 100 + 1;
}
} while (theGuesser == theNumber);

cout << "\nLooks like he guessed it in " << tries << " tries! Uh oes!";

return 0;
}

Any help is appreciated!

Edit: I think it might be my loop, considering switching to a single while loop versus the do. Any invoice would be helpful, as I can't test it at the moment, I have to go run some errands.

Double edit: Ugh, I just realized the problem. Will attempt to fix it asap. 8)

Okay, I really have to get going, but this is the new source. Now It won't cout the guess and ends the loop. Any help on my half-assed new source would be appreciated! 8)

Ooookay, I'm sorry, just delete this. I fixed it. I'm a stubborn little boy. ._.

Oh, I didn't see your code. I'mma toy with that soon as I get some time. I ended up with this:

You're only real problem was this:

(Toggle Plain Text)

while (theGuesser == theNumber)

It should have been !=, as you finally realised.

Oh, and please use [code] tags, not [quote] tags next time.
