Nixie.c(8): error C267: 'SelectNixie': requires ANSI-style prototype

This error message suggests that there is a problem with the way the function "SelectNixie" is defined or declared. The compiler is expecting an ANSI-style prototype for the function.

An ANSI-style prototype includes the return type of the function, the name of the function, and the type and name of each parameter, separated by commas and enclosed in parentheses.

To fix this error, make sure that the function "SelectNixie" is declared with an ANSI-style prototype before it is used in the code. The prototype should include the return type of the function, the name of the function, and the type and name of each parameter.

For example:

int SelectNixie(int nixieNum);

Make sure that the function definition matches the prototype and that it includes the return type, the function name, and the type and name of each parameter.

By providing a correct ANSI-style prototype, the compiler will be able to correctly compile the code and resolve any issues related to the function "SelectNixie".
