Compiler Error C3533

'type': a parameter cannot have a type that contains 'auto'

A method or template parameter cannot be declared with the auto keyword if the default /Zc:auto compiler option is in effect.

To correct this error

1. Remove the auto keyword from the parameter declaration.

Examples

The following example yields C3533 because it declares a function parameter with the auto keyword and it is compiled with /Zc:auto.

// C3533a.cpp// Compile with /Zc:autovoidf(auto j) {} // C3533

The following example yields C3533 in C++14 mode because it declares a template parameter with the auto keyword and it is compiled with /Zc:auto. (In C++17, this is a valid definition of a class template with a single non-type template parameter whose type is deduced.)

// C3533b.cpp// Compile with /Zc:autotemplate<auto T> classC {}; // C3533
