more than one storage class specified

In C programming language, a storage class defines the scope, visibility, and lifetime of a variable. There are four storage classes in C: auto, register, static, and extern.

The error message "more than one storage class specified" occurs when a variable is declared with more than one storage class specifier. For example:

static auto int x; // error: more than one storage class specified

In this example, the variable x is declared with both static and auto storage class specifiers, which is not allowed.

To fix this error, you need to remove one of the storage class specifiers from the variable declaration. For example:

static int x; // fixed: only one storage class specifier
