Remove even numbers

Make a program that takes an input that determines how many inputs the user wants to submit input_count.

Then collect input_count inputs and place them into a std::vector<int> array.

After collecting the numbers, print the array using a function print_vector (you have to create this function).

Then remove all even numbers from the array, and print it again.

Hint

You can use vec.erase(vec.begin() + index) to removePa the element with index index from a std::vector (vec in this case).

Answer

#include <iostream>
#include <vector>

void print_vector(std::vector<int> vector)
{
	std::cout << "Current Array:\n";
	for (int i = 0; i < vector.size(); i++)
	{
		std::cout << vector[i] << " ";
	}
	std::cout << "\n";
}

int main()
{
	int input_count;
	std::cout << "How many inputs do you want to submit? ";
	std::cin >> input_count;

	std::vector<int> inputs;
	for (int i = 0; i < input_count; i++)
	{
		std::cout << "Input " << i + 1 << ": ";
		int input;
		std::cin >> input;
		inputs.push_back(input);
	}

	print_vector(inputs);

	// Remove all even numbers
	for (int i = 0; i < inputs.size(); i++)
	{
		if (inputs[i] % 2 == 0)
		{
			inputs.erase(inputs.begin() + i);
			i--; // Adjust index to account for the removed element
		}
	}

	print_vector(inputs);
}
