# Exercise 1.11

 Orvin Welchez · August 13, 2014 I'm trying to work an exercise from the book "Primer 5th edition"(Write a program that prompts the user for two integers. Print each number in the range specified by those two integers).When I type the 1 and 10 for example, the program only print up to number 9 and the same happens when I do 10 to 1, it only print up to number two always missing the last number. Any help will be greatly appreciated, Thank you!Here is the code:#include int main ()    {        int v1 = 0, v2 = 0;    std::cin >> v1 >> v2;    while (v1v2)    {        std::cout << v1 << std::endl;        v1--;    }    return 0;    }

 Orvin Welchez · August 14, 2014 I found the following code super easy to understand and you provided me with a nice trick with swapping the numbers with "if" and "else" statements, I truly appreciate your help Brandon, Thank you!#include int main (){int number1 = 0, number2 = 0;int lowNumber = 0, highNumber = 0;std::cin >> number1 >> number2;if(number1 > number2){lowNumber = number2;highNumber = number1;}else{lowNumber = number1;highNumber = number2;}while(highNumber >= lowNumber){std::cout << lowNumber << std::endl;lowNumber++;}return 0;} Brandon Elliott · August 13, 2014 I see what you're talking about now with the code blocks causing some issues. Strangely enough, it doesn't do that in internet explorer (I posted those replies while I was at work, and they enforce a strict browser policy)Now that I'm on google chrome at home, I see what you're talking about Orvin Welchez · August 13, 2014 Wow how dummy I am lol, I'm sorry I got all confused, so < and > get replace by the "less than" and "greater than" signs.I will try to name variables better for future reference and thank you for the advice, I'll try to stick to it.I have done Bucky's C++ videos up to number 41 but then I saw someone suggesting this "C++ Primer 5th Edition Book" and I'm starting over to make sure that I haven't missed anything important and I kinda like this book so far. Brandon Elliott · August 13, 2014 i don't see the characters you're talking about but i'm assuming they are the greater than and less than signs.``#include int main (){int number1 = 0, number2 = 0;int lowNumber = 0, highNumber = 0;std::cin >> number1 >> number2;if(number1 > number2){lowNumber = number2;highNumber = number1;}else{lowNumber = number1;highNumber = number2;}while(highNumber >= lowNumber){std::cout << lowNumber << std::endl;lowNumber++;}return 0;}``you can see in the code the 2 inputted numbers are saved to variables lowNumber and highNumber according to which one is higher or lower than the other. this makes it so the user can input for example 0 and 10 or input 10 and 0 and it will still print out 0-10 either way.you could also make it so that if you enter 0 and 10 it will print out 0-10 and if you enter 10 and 0 it will print out 10-0.like this:``#include int main (){int number1 = 0, number2 = 0;std::cin >> number1 >> number2;if(number1 > number2){while(number1 >= number2){std::cout << number1 << std::endl;number1++;}}else{while(number1 <= number2){std::cout << number2 << std::endl;number2--;}}return 0;}`` Orvin Welchez · August 13, 2014 For loops have not been introduced before that exercise and even though I have some experience working with For loops, I'm trying to go by the rules and do it with only the requested knowledge.I'm trying to understand this > and < but I have no clue what it is: std::cin >> lowNumber >> highNumber;std::cout << i << std::endl;std::cout << i << std::endl; Brandon Elliott · August 13, 2014 This is how I would do it with for loops.``#include int main (){int number1 = 0, number2 = 0;int lowNumber = 0, highNumber = 0;std::cin >> number1 >> number2;if(number1 > number2){lowNumber = number2;highNumber = number1;}else{lowNumber = number1;highNumber = number2;}for(int i = lowNumber; i < (highNumber + 1); i++){std::cout << i << std::endl;}return 0;}``sorry i originally got confused about what you were trying to do in your code with the 2  different loopsyou always want to practice good variable naming. it makes your code more readable Orvin Welchez · August 13, 2014 I tried adding the = sign but when I run the program it also prints 11 then it goes back to 10 and returns 0. Brandon Elliott · August 13, 2014 it's because 10 is not < 10 and 1 is not > 1you'd want to change your while loops to bewhile (v1<=v2)andwhile (v1>=v2)
