Reading and Writing Programs

There are various programming languages. But basic items are not so different. I introduce such items below.

Key-words

Repeat

Repeat same procedure by computers

If

Teach condition and procedure

Variable

Box of value

• When we write " A = 'Tokyo' ", it means we put the value 'Tokyo' into the box A. And if we write " B = A " as the next step, it means we put the value 'Tokyo' into the box B.
• When we write " A = A + 1 ", it means " Use new A which is added 1 to the old A ".

Nesting

Process is written from up to down.

Program is similar to novels. Different points is that program has "repeat" and "if" structure.
