need help fixing this program

im trying to run this program but i keep getting the error "the variable 'b' is being used without being initialized". i really need help

Code:

---


#include<iostream>
using namespace std;
int main()
{
int a,b;
cout <<" a = " <<a <<" and b = " <<b;
cout << "\n " <<b << "\n" <<a;
return 0;
}

Well, yes. It is probably a warning rather than an error, but it is indeed true that b (and a) is used without being initialised. What are you trying to do in this program?

you're displaying the value of both variables without ever assigning a value to them. C++ does not automatically initialize (assign a default value) to anything, so you have to do this yourself.

this question is part of an assignment, so i know i have to fix it so that it runs but im not sure

Without knowing what you are trying (or are supposed) to do, we cannot say any more than your compiler has told you. What I can do is give you an example of initialisation:

Code:

---

#include<iostream>

using namespace std;

int main()
{
    int a = 1, b = 2;
    cout << " a = " << a << " and b = " << b;
    cout << "\n " << b << "\n" << a;
    return 0;
}

Notice that I have indented the code to make it more readable.
