Question

Write a for loop to populate vector userGuesses with NUM_GUESSES integers. Read integers using cin. Ex: If NUM_GUESSES is 3 and user enters 9 5 2, then userGuesses is {9, 5, 2}.

Answer 1

#include <iostream>
#include <vector>

#define NUM_GUESSES 3

int main()
{
std::vector<int> userGuesses;
for (int i = 0, input; i < NUM_GUESSES; i++)
{
std::cin >> input;
userGuesses.push_back(input);
}
}

Answer 2

The solution code is written in C++.

1. vector<int> userGuesses;
2. int NUM_GUESSES = 3;
4. int i;
5. int inputNum;
7. for(i = 1; i <= NUM_GUESSES; i++){
8. cin>>inputNum;
9. userGuesses.push_back(inputNum);
10. }

Step-by-step explanation:

By presuming there is a vector, userGuesses and the NUM_GUESSES is 3 (Line 1 - 2).

Next we can create a for-loop that will run for NUM_GUESSES round of iterations. In each iteration, we use cin to get an input number and then use push_back method to add the input number to the userGuesses vector (Line 7 - 10).
