Number Guessing game does not output right - c++

Question

Im trying to create a number guessing game where the user enters number integers they want to guess and the range of those integers 1 to (m). Then the computer randomly generates numbers in that range for the user to guess. The user guesses until they get all the numbers correct For example:
Enter number integers: 4
Enter the range of those integers from 1 to (m): 6
Enter guess: 2 3 1 4
3 of your guesses are correct. Guess Again
Enter guess: 2 3 1 6
Correct. Would you like to play again.
The Output I get right now is:
Enter number integers: 4
Enter the range of those integers from 1 to (m): 6
Enter your guesses for the 4 in the range from 1 to 6 that you have selected: 2 3 1 4
There are three files for this game.cpp, game.h, and driver.cpp. Please let me know if you find anything else wrong with my code. This is my 1st program I have written in C++.

Answer 1

The line
inputGuess.push_back(n);
adds only one element, but you are using n elements here:
// Get user guesses integers
for (int i = 0; i < n; i++) {
std::cin >> inputGuess[i];
}
Therefore an out-of-range access happens when n is larger than 1.
To set the number of elements to n, you should use resize() instead like this:
inputGuess.resize(n);
