how do i populate a vector with a for loop

[seungyeon]

using only these declartions and 1 for loop

#include <iostream>
#include <vector>
using namespace std;

int main() {
   const int NUM_GUESSES = 3;
   vector<int> userGuesses(NUM_GUESSES);
   

   
   return 0;
}

What would you like to populate the vector with? User guesses I guess? Just adding on to our code you can do this:

#include <iostream>
#include <vector>
using namespace std;

int main() {
	const int NUM_GUESSES = 3;
	vector<int> userGuesses(NUM_GUESSES);

	for (int count = 0; count < NUM_GUESSES; count++)
	{
		cout << "Guess " << count+1 <<" Guuess a number" << endl;
		cin >> userGuesses[count];

	}

	for (int count = 0; count < userGuesses.size(); count++)
	{
		cout << "Guess " << count+1 << " was: " << userGuesses[count] << endl;
	}

	return 0;
}

Personally, I would use this instead but both work.

#include <iostream>
#include <vector>
using namespace std;

int main() {
	const int NUM_GUESSES = 3;
	int guess;
	vector<int> userGuesses;

	for (int count = 0; count < NUM_GUESSES; count++)
	{
		cout << "Guess " << count+1 <<" Guuess a number" << endl;
		cin >> guess;
		userGuesses.push_back(guess);
	}

	for (int count = 0; count < userGuesses.size(); count++)
	{
		cout << "Guess " << count+1 << " was: " << userGuesses[count] << endl;
	}

	return 0;
}
