What is assignment executable and declaration in vb programming?

Answer 1

Assignment refers to the assignment operator (=) which can be used to copy the value of one object to another object of the same type.

Executable refers to the machine code executable (EXE or DLL) produced by the language compiler.

A declaration introduces a new name into the language. The new name could refer to a class, a function or a variable, but the compiler won't know what that name means unless you declare it accordingly. Once declared, the compiler can determine which operations are appropriate for that name and thus prevent any incorrect usage of that name.
