This article describes how to use a set of condition check statements to create programming alternatives. C++ programming uses the { and } symbols for each block of action that means the instruction set in each block is always executed from top to bottom, with one action at a time, and can be executed by creating a condition. In addition, the desired part of the command can also be repeated by loop, which will be discussed in the next article.

This article compiles information about operators used in C++ to write expressions of commands. Operator marks are divided into five groups: Arithmetic, Boolean, Comparison, bitwise, and Compound.

This article discusses variables, data types and constants for use with Arduino, the basis of programming. This is because programming has principles, as Niklaus Wirth has said since 1976 in his book that

Algorithms + Data Structures = Programs

A program is a problem-solving algorithm that processes data, which is the main reason for the difference between computation and program.
