New to coding, needing some help.

I'm new to coding and I'm trying to make a program that will simply add two numbers together and give an answer.

Code:

---

#include <iostream>

using namespace std;

int main ()
{
    float a, b, c;
    c = a+b;
   
    cout <<"Please give me two numbers to add" << endl;
    cin >>a>>b;
    cout <<"The answer is "<< c << endl;

    return 0;
}

---

Some assistance with this would be appreciated. I'm using Bloodshed's Dev-C++ as a compiler.

the problem is how you're initialising the variable c. You're trying to initialise it to equal the sum of a and b, but you only ask for values of a and b after wards. Remember, C++ is a procedural language, and you have to initialise c only after you get the values of and b.

something like this

Code:

---



cin >> a >> b;

float c = a+b;

---

c = a + b doesn't mean anything until you have a + b. Move that down so that c doesn't contain garbage:

Code:

---

    cin >>a>>b;
    c = a + b;

---

Hope that helps - I'm new too -

dra beat me to it!

Oh, all right! Thanks!

Hmm, I changed the code to this:

Code:

---

#include <iostream>

using namespace std;

int main ()
{
    float a, b, c;

   
    cout <<"Please give me two numbers to add" << endl;
    cin >>a>>b;
    c = a+b;
    cout <<"The answer is "<< c << endl;

    return 0;
}

I don't understand the problem...

Problem? Are you getting a compile error? That code works correctly for me.

Can't see the result? You need to add

Code:

---

cin.ignore();
cin.get();
