Need help with "if else" program

[MisterBren]

Need a little help with this program, any help or advice would be appreciated! Here is the question it asks..

Suppose that sale and bonus are double variables. Write an if.
..else statement
that assigns a value to bonus as follows: If sale is greater than $20,000, the value assigned to
bonus is 0.10; If sale is greater than $10,000 and less than or equal to $20,000, the value
assigned to bonus is 0.05; otherwise, the value assigned to bonus is 0. Print out the sale and
bonus values

#include <conio.h> // For function getch()
#include <cstdlib>  // For several general-purpose functions
#include <fstream>  // For file handling
#include <iomanip>  // For formatted output
#include <iostream>  // For cin, cout, and system
#include <string>  // For string data type
using namespace std; // So "std::cout" may be abbreviated to "cout"

int main()
{
	int x = 10;
	if (x > 20000)
	{
		printf_s("x is .10!\n");
	}
	else
	{
		printf_s("x is 0.10!\n"); // this statement will not be executed
	}

	x = 1;
	if (10000 < x <= 20000)
	{
		printf_s("x is 0.05!\n"); // this statement will not be executed
	}
	else
	{
		printf_s("x is not 0.05!\n");
	}

	return 0;
}

I think the thing that is messing with me is that the only applications I've made so far is where the user inputted a value. Is that not the case for this problem?

alright, this is where I'm at now..

#include <conio.h> // For function getch()
#include <cstdlib>  // For several general-purpose functions
#include <fstream>  // For file handling
#include <iomanip>  // For formatted output
#include <iostream>  // For cin, cout, and system
#include <string>  // For string data type
using namespace std; // So "std::cout" may be abbreviated to "cout"

int main()
{
	double sale;
	double bonus;

	if (sale > 20000)
	{
		cout << "The bonus is 0.10" << endl;
	}
	else if (10000 < sale <= 20000)
	{
		cout << "The bonus is 0.05" << endl;
	}
	else if (sale == 30)
	{
		cout << "The bonus is 30" << endl;
	}
	else
	{
		cout << "Value of sale is not matching" << endl;
	}
	cout << "Exact value of a is : " << sale << endl;

	return 0;
}

Line 11: sale is an uninitialized variable (garbage).

Line 18: You can't write an if statement like that. That statement evaluates as:

  if ( (10000 < sale) <= 20000)
       ^^^^^^^^^^^^^ evaluates to true or false

Is that not the case for this problem?

The problem description doesn't specify where the value of sale comes from. You can input it. Or you can set it as a constant.
