The deduction rules for auto are based on the rules for template argument deduction. So now that you know these template argument deduction rules, you also know the corresponding auto deduction rules!

​ ​auto​ t1 = nonConstInt; ​// non-const object​

​ ​auto​ t2 = constInt; ​// non-const object​

​ ​auto​ &t3 = nonConstInt; ​// reference to non-const object​

​ ​auto​ &t4 = constInt; ​// reference to const object​
