Write a program that prompts the user for two integers. Print each number in the range specified by those two integers

#include <iostream>

int main()
{
    int small = 0, big = 0;
    std::cout << "please input two integers:";
    std::cin >> small >> big;

    if (small > big) {
        int tmp = small;
        small = big;
        big = tmp;
    }

    while (small <= big) {
        std::cout << small << " ";
        ++small;
    }
    std::cout << std::endl;

    return 0;
}

Output:
