More than a year before the video copy of today only found the bright spot behind, so continue to learn!

A problem was found in the morning. "Error C2275:" xxxxx ": Use this type as an expression illegal".

Baidu a bit. Explained below.

This error is due to the compiler of c requiring the declaration of a variable to be placed in the head of a function block. This is a problem with programming habits.

Compile C code in VS, often error C2275 errors, the result is that the variable is not defined in the right position, should be at the top of the function block.

The solution is to place the declaration of the variable all at the beginning of the variable's survival block.
