Trouble with a beginner coding challenge - c++

Question

Write a program that continues to ask the user to enter any number other than 5 until the user enters the number 5.
Then tell the user "Hey! you weren't supposed to enter 5!" and exit the program.
★ Modify the program so that after 10 iterations if the user still hasn't entered 5 will tell the user "Wow, you're more patient then I am, you win." and exit.
★★ Modify the program so that it asks the user to enter any number other than the number equal to the number of times they've been asked to enter a number. (i.e on the first iteration "Please enter any number other than 0" and on the second iteration "Please enter any number other than 1"m etc. etc. The program must behave accordingly exiting when the user enters the number they were asked not to.)
I got most of the program to work. I have it to a point where it asks for a number starting at 0 and going up, it gives the user the patient message after 10 tries, and exits the program if they enter the number they are not supposed to. However if the user inputs the number above what it tells you not to enter, the program exits with no message.
I do not really know what to search to fix this issue. I have however tried to move some things around, and got rid of some redundant variables.
Any hints would be appreciated, please do not give me the answer up front! Here's what I have so far.
#include <iostream>
int main()
{
const int GUESS = 1; // constant for number of tries
const int PATIENCE = 10; // constant for message at 10 tries
int UserNum; // player input
int InputNum = GUESS; // intializes GuessNumber
// asks for player input
do
{
std::cout << "Enter any number other then "<< InputNum << ": ";
std::cin >> UserNum;
// exits program if user inputs the number displayed
if (UserNum == InputNum)
{
std::cout << "Hey! you weren't supposed to enter " << InputNum << "!\n";
}
// increase the Guess counter if they dont enter the number displayed
else if (UserNum != InputNum)
{
InputNum++;
}
if (InputNum == PATIENCE)
{
std::cout << "Wow, you're more patient then I am, you win.\n";
break;
}
} while (UserNum != InputNum);
return 0;
}

Answer 1

your problem is in do while loop condition
statements are executed first and condition are checked later
for example
InputNum is initialized as 1
so if you enter 2 as input for UserNum , in the else if condition ,InputNum will be incremented to 2
when this condition is evaluated
while (UserNum != InputNum)
it will be false as 2==2
loop breaks
solution
change PATIENCE = 11 and use
while (1)
// this will run infinitely but it will break after 10 iteration or when u press the same number which u shouldn't
instead of
while (UserNum != InputNum)
the full program
#include <iostream>
int main()
{
const int GUESS = 1; // constant for number of tries
const int PATIENCE = 11; // constant for message at 10 tries
int UserNum; // player input
int InputNum = GUESS; // intializes GuessNumber
// asks for player input
do
{
std::cout << "Enter any number other then " << InputNum << ": ";
std::cin >> UserNum;
// exits program if user inputs the number displayed
if (UserNum == InputNum)
{
std::cout << "Hey! you weren't supposed to enter " << InputNum << "!\n";
break;
}
// increase the Guess counter if they dont enter the number displayed
else if (UserNum != InputNum)
{
InputNum++;
}
if (InputNum == PATIENCE)
{
std::cout << "Wow, you're more patient then I am, you win.\n";
break;
}
} while (1);
system("pause");
return 0;
}

Answer 2

Hey try this program it does exactly what you want.
#include <iostream>
int main ()
{
int GUESS = -1; //loop variable
const int PATIENCE = 10; // constant for message at 10 tries
int InputNum; // input from user
std::cout << "PATIENCE Test" << "!\n";
do
{
GUESS++;
// asks for player's input
std::cout << "Enter any number other than " << GUESS << ": ";
std::cin >> InputNum;
// exits program if user inputs the number displayed
if (GUESS == InputNum)
{
std::
cout << "Hey! you weren't supposed to enter " << GUESS << "!\n";
break;
}
if (GUESS == PATIENCE)
{
std::cout << "Wow, you're more patient then I am, you win.\n";
break;
}
}
while (GUESS != InputNum);
return 0;
}
