What is wrong with this c++ code?

Question

#include <iostream>
using namespace std;

int main()
{

int a;

cout << "a is" << endl;
cin >> a;

int b;

cout << "b is" << endl;
cin >> b;

if (a > b) {
cout << "greatest is " << a << endl;
}
if (b > a) {
cout << "greatest is " << b << endl;
}
}

Answer 1

Error: You're printing a and b on the console before it is defined in line 6 and 9.
To avoid this, swap 6th and 7th, and swap 9th and 10th line!

Answer 2

you have put two if it is worng
but you have to put if and else like this👇

if (a>b)
{
cout<<"greatest is a:"<<a<<endl;
}
else(b>a)
{
cout<<"greatest is b:"<<b;
}

Answer 3

My suggestion is to :-

1. First set all the variables at the beginning after "int main (){"

2. Then you can then get user input with the "cin >>".

3. Now use the "if else" statements and there respective conditions.
