Need help! C++ basic arithmetic

Question

Hello, I get the right answer 12.42 but my code is wrong.

#include <iostream>
using namespace std;

int main() {

double length= 5.4;
double width= 2.3;
//cin >> length;
//cin >> width;
double area = 5.4*2.3;
cout <<area;

return 0;
}

Answer 1

You should take the inputs from the user, don't define yourself.

So, your code must be,

#include <iostream>
using namespace std;

int main() {

double length;
double width;
cin >> length;
cin >> width;
double area = length*width;
cout <<area;

return 0;
}

I think you are trying to resolve a challenge which requires user input to create the values.

Since this will be tested with hidden values, you must create a code with flexibility.

Might I suggest you review the following code snippet to see if it helps.

#include <iostream>
using namespace std;

int main() {

double length, width, area;
cin >> length;
cin >> width;
area = length * width;
cout << area;

return 0;
}

It works for me.
Are you putting in your numbers on separate lines?
