So the assignment is to write a program that have the user entered 3 numbers and than it will sort it by ascending order. Here are the code I wrote, but it won't compiled and I kept on getting an error message "Using uninitiazed memory" for all the variables. Can someone please help take a look and see whats going on?
#include <iostream>
using namespace std;
int main()
{
//variables
int num1, num2, num3;
int lowest, middle, highest;
//user inputs
cout << "Please enter the first number:" << endl;
cin >> num1;
cout << "Please enter the second number:" << endl;
cin >> num2;
cout << "please enter the third number:" << endl;
cin >> num3;
//sorting the numbers
if (num1 < num2 && num1 < num3)
{
lowest = num1;
if (num2 > num3)
{
highest = num2;
middle = num3;
}
}
if (num1 < num2 && num3 < num1)
{
lowest = num1;
if (num2 < num3)
{
middle = num2;
highest = num3;
}
}
if (num1 > num2 && num3 > num1)
{
middle = num1;
if (num2 < num3)
{
lowest = num2;
highest = num3;
}
}
if (num1 < num2 && num3 <num1)
{
middle = num1;
if (num2 > num3)
{
highest = num2;
lowest = num3;
}
}
if (num1 > num2 && num1>num3)
{
highest = num1;
if (num3 > num2)
{
middle = num3;
lowest = num2;
}
}
if (num1 > num2 && num1 > num3)
{
highest = num1;
if (num2 > num3)
{
middle = num2;
lowest = num3;
}
}
//output to user
cout << "The number you entered in ascending orders are: " << lowest << " , " << middle << " , and " << highest << endl;
return 0;
}

* File Name : sort.cpp

* There is a chance for your program to get errors
* because when the input is 1,2,3
* in first if block lowest will be set and the remaining middle and
highest
* are not set and printing them will results in garbage
values.
*
* so i have changed your code little bit.
* consider the possibilities of sorting order of 3 variables
NUM1,NUM2,NUM3
NUM2,NUM1,NUM3
NUM3,NUM1,NUM2
NUM1,NUM3,NUM2
NUM2,NUM3,NUM1
NUM3,NUM2,NUM1
*
* Now first check num1 is both less than num2,num3
* if less than, lowest = num1,
* check if num2 < num3
* then middle =
num2, highest = num3.
* if not
* middle = num3,
highest = num2.
* Above block checks the two permuations -> NUM1,NUM2,NUM3,
NUM1,NUM3,NUM2
*
* if above block not satisfied check num2 is both less than
num1,num3
* if less than, lowest = num2,
* check if num1 < num3
* then middle =
num1, highest = num3.
* if not
* middle = num3,
highest = num1.
*
* Above block checks the two permuations -> NUM2,NUM1,NUM3,
NUM2,NUM3,NUM1
*
* if above block not satisfied check num3 is both less than
num1,num2
* if less than, lowest = num3,
* check if num1 < num2
* then middle =
num1, highest = num2.
* if not
* middle = num2,
highest = num1
* Above block checks the two permuations -> NUM3,NUM1,NUM2,
NUM3,NUM2,NUM1
* so all the 6 permutations are completed with 3 blocks.
* comment if you have any doubts.

Enter another value." , if 1 ) numbers are not within range 2) a blank is entered 3) other characters (that are not numbers) are entered and 4) numbers with decimals or negatives are entered. int num1; int num2; for(int i = 1; i <= 4; i++) { cout << "Enter number...
I'm kind of new to programming, and I am having trouble figuring out why my program isn't running. Below is the code that I wrote for practice. I will comment where it says the error is. So the error that I'm getting is "error: no match for 'operator>>' (operand types are 'std::istream {aka std::basic_istream<char>}' ". I'm not sure why I'm getting this because I added the library <iostream> at the top. Thank you. Code: #include <iostream> using namespace std; class...

So far your TestEqual functions have tested values but haven't made any changes... Q: If you changed one of the variable values in your function, would it change the value of the variable in main? Why? Q: What are the two options for passing parameters into a function? (by _________ and by __________) What's the difference? Write a new function, MakeEqual, that takes two integers and if they are not equal (tested using your TestEqual function), displays a message and...
Assignment Develop a program to analyze one or more numbers entered by a user. The user may enter one or more numbers for analysis. Input should be limited to numbers from 1 through 1000. Determine if a number is a prime number or not. A prime number is one whose only exact divisors are 1 and the number itself (such as 2, 3, 5, 7, etc.). For non-prime numbers, output a list of all divisors of the number. Format your...
