[C++] Trouble with if statement

[NeatSquidYT]

Hi,

I'm learning C++ and have made a simple program to make it so a user can input if they want to use division or multiplication, and they can enter their number and get a result. For some reason I have errors with the if statement if I try and build it.

Needs to be: if (dorm == "d")

 

The = operator sets dorm to "d"; the == returns a boolean which is what you need for an if statement.  In almost any coding language comparing to values is == and setting a value is just =.

Thank you I always forget to do ==

Try: if (dorm == "d")

In Javascript you even need 3 of '='. (most of the time)

if(a===b)

D:

2 of them works fine iirc, it's just how accurate you want it to be.

That;s why I said "most of the time".

 

3 '=' also checks to see if they are the same data type.

No you don't because correct me if I'm wrong but the extra = sign just allows you to make sure they're also the same datatype. As in, both are int's and both === 2 or both are strings and both === 2.

Exactly.
