Basic elements of Program Design

Data Types: eight basic categories
Operators: calculate the value ratio to determine whether the value is true or false
Stream Control: Two-choice, three-cycle stream jump function for calling

 

Note:

The data types mainly include Boolean char byte int short long float double, eight basic types and class types.

The main operators include: +-*/% + -- For numeric operations; logical operations & |! & | ^ ~; Relational operation <>! === Value assignment = bit operation >><>>

Process control mainly includes: If switch, two selection flows, while do while for, three loop flows, break, continous flow jump, and function call control flow.
