Need help with fixing C++ code?

[newcppguy]

Ok, here's the thing. I want to have a program that tells the user to enter the height and width of a poster.

Then i want it to (based on the user entered numbers) to tell the user to use A4, A3, A2 or A1 paper. Must reflect portrait and landscape view.

I'm new at C++, and so i want you to tell me what is wrong with the code I have so far, and show me how you fixed it (if you fixed it for me) or tell how to do it on my own.

I only want to use what I know so far for the code, so nothing for advanced C++ please .

Here is the code i have so far:

______

#include <iostream>
using namespace std;

int main()
{
int pos_wid, pos_hei;

cout << "Enter the dimensions of the poster in mm: " << endl;
cin >> pos_wid >> pos_hei;

if (pos_wid => 210 && pos_hei <= 297) || (pos_wid <= 297 && pos_hei => 210)
{
cout << "Use A4" << endl;
}
else if (pos_wid => 297 && pos_hei <= 420) || (pos_wid <= 420 && pos_hei => 297)
{
cout << "Use A3" << endl;
}
else if (pos_wid => 420 && pos_hei <= 594) || (pos_wid <= 594 && pos_hei => 420)
{
cout << "Use A2" << endl;
}
else if (pos_wid => 594 && pos_hei <= 810) || (pos_wid <= 810 && pos_hei => 594)
{
cout << "Use A1" << endl;
}
else
{
cout << "Not in stock" << endl;
}
system("pause>null");
}

Oh and please don't laugh if you find a lot of errors , like I said i'm new.

Did it compile?
Did you run it?
Did it work?

No.

Couldn't didn't work.

No.

Would be a good idea to tell what the compiler thinks about your code.
Anyway there is no operator =>. use >= instead.

=> should be >=

For help with compiling problems, it's best to tell us what the errors are that you're getting.

Also, please use code tags.

i only corrected the first if.

if (((pos_wid >= 210) && (pos_hei <= 297)) || ((pos_wid <= 420) && (pos_hei >= 297)))
{ 
	cout << "Use A4" << endl;
}

Looking at it again, I think you want <= 210, not >=.
