I'm trying to print out the size of various data types I have in an array as strings, like so:

printf("%lu", sizeof(list_of_datatypes[i]))

A string for example would be "char", or "unsigned int". Is there a way I could get sizeof to see them as the reserved words they are in c?

CodePudding user response：

You can't do that. The sizeof operator takes expressions or type names as an argument, and the result is evaluated at compile time (except for variably-modified types). It does not treat a string such as ”char” as a type name.

Is there any way to explicitly convert it?

No.
