Problem with exercise

[Oizys]

Idk what I'm doing and it keeps saying "'INCHES_PER_FOOT' is used uninitialized in this function 'CENTIMETERS_PER_INCH' is used uninitialized in this function. Trying to get it to stop saying that and then make INCHES_PER_FOOT and CENTIMETERS_PER_INCH display some values. All help is highly appreciated.

  // my second program in C++
#include <iostream>

using namespace std;

int main ()
{
    //declare variables
	int feet;
	int inches;
	int totalInches;
	int INCHES_PER_FOOT;
	int CENTIMETERS_PER_INCH;
	double centimeter;
	
cout << "Enter two integers, one for feet and one for inches and one for inches: ";
cin >> feet;
cin >> inches;

cout << "The numbers you entered are ";
cout << feet; 

cout << "for feet and "; 
cout << inches; 

cout << "for inches ";
cout << endl;

totalInches = INCHES_PER_FOOT * feet + inches;

cout << "The total number of inches = ";
cout << totalInches;
cout << endl;

centimeter = CENTIMETERS_PER_INCH * totalInches;

cout << "The number of centimeters = ";
cout << centimeter;
cout << endl;
system ("pause");

return 0;
}

well, they are!
it isn't an error to fail to initialize but some settings warn you about it.
but it is an error (at the very least, a bug) to use the value without it having a valid value, which you do on line 29.
the names indicate they might be conversion factors.
so, most likely, you want
const int inches_per_foor = 12; for example.

I understand I have to assign a value to it, how to put the "const int inches_per_foot=12" just typing it in at line 29 doesn't do anything. Also how do I make a space in-between line 17 and line 18 for example.
