This does not work properly please check for alterations .Refer below as i have entered the code.

What I have tried:

C++

<pre>
#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;

int main()
{
	srand(time(NULL));

	int tries = 0;
	int iNum;
	int UpperLim = 100;
	int LowerLim = 10;
	int iCompNum;


	cout << "Enter a number: ";
	cin >> iNum;

	do
	{
		iCompNum = rand() % (UpperLim - LowerLim) + LowerLim;

		cout << "\nComputer's guess(" << 10 - tries << " tries left): ";
		cout << iCompNum;
		++tries;

		if (iNum > iCompNum)
		{
			cout << "\nThe number is less than the entered..!(" << 10 - tries << " tries left)\n\n";
			LowerLim = iCompNum+1;
		}
		else if (iNum < iCompNum)
		{
			cout << "\nThe number is greater than the entered..!(" << 10 - tries << " tries left)\n\n";
			UpperLim = iCompNum-1;
		}
		else if (iNum == iCompNum)
		{
			cout << "\nYou got my number!!!\n\nYou guessed the number in just " << tries << " tries!\n\n";
		}
		else if (tries >= 10)
		 {
			cout << "You Lose!Correct Answer is:" << iNum << endl;
}
	} while (iNum != iCompNum);
	

	return 0;
}

In what way does this "not work properly"?

Hi thank you for taking your time. So when the program runs out of tries it doesnt output the comment "You Lose!Correct Answer is:".

"This does not work properly"
What does that mean? Perhaps the fact that the computer is doing the guessing but you are telling the user that they win or lose.

The problem is at the end of the loop. If you run out of tries then you need to use a break statement to get out of the loop. And after exiting the loop you should print the fail or success message, depending on whether iNum and iCompNum are equal or not. So change it to:

C++

        else if (tries >= 10)
        {
             break;
        }
    } while (iNum != iCompNum);
    if (iNum == iCompNum)
    {
        cout << "You Lose! Correct Answer is:" << iNum << endl;
    }
    else
    {
        cout << "You win, I cannot find it" << endl;
    }
    
    return 0;
}
