I trying to port over the following code:

byte DIV_3_OF_5[8] = {
  B11100, 
  B11100,
  B11100,
  B11100,
  B11100,
  B11100,
  B11100,
  B11100
}; // 3 / 5

byte DIV_4_OF_5[8] = {
  B11110, 
  B11110,
  B11110,
  B11110,
  B11110,
  B11110,
  B11110,
  B11110
}; // 4 / 5

What is the C syntax for this, and how to define 0s and 1s in this case? Do I need to convert the number to hex?

What I have tried:

I have tried to migrate it over without success.

Since that the values are all the same it should be easy to use the hexadecimal value 0x1E instead of the binary values.

Some compilers support binary literals with a 0b or 0B prefix. They are not part of the C standard but has been introduced with C++14.

If you use such a compiler (e.g. GCC: Using the GNU Compiler Collection (GCC): Binary constants[^] ) it is sufficient to insert a zero. If not, you have to convert the values to hex.
