C & C++

Fall-through in switch cases is often considered risky. Hence consider adding an unconditional break for each switch clause.

Default case provides switch statements with fallback, and in general is a good to have. Hence consider adding default case to switch.

Using special-meaning characters in header names can produce errors in parsing.

Consider cleaning up header names.

Modifying the control variable of a for loop in its body can make the code harder to read.

Consider using a while loop, or move the modification into the for loop's update expression.

Raw string literals are used in C++ to avoid using escape characters. They can be used to express all types of string literals. A raw string literal enables you to express a string without having to perform extra construction or conversion steps. For example, if you want to express a string that contains a backslash, you can use a raw string literal to avoid having to escape the backslash.
