The character types in 1 and C languages are char types, which generally account for 1 byte, so char types are generally used to describe byte arrays. take for example

Charles? SZ _ byte[256]； 2. Sometimes, in order to read files, character types will be described as byte types. You need to use typedef keyword. take for example

typedef？ Charles? Bytes;

Bytes? buff[ 16]？ =? {0};
