Question

write a program to print the summation of any two numbers by using basic 256​

Answer 1

The first command to learn is “print”, which prints out its arguments to the text output screen. If the argument is a text string, delimited by quote (“) – and printed in red – then it is printed as-is. If it were a numerical expression, the evaluated result of the expression is printed out. Most of the math expressions using ordinary operators like +, -, / and * are available.

Print command, by default, makes a new line. In the third line, the print statement is ended with a semicolon(;), which instructs Basic256 do not start a new line, and the output is printed next to the last print result. Thus, the third line prints out “1+3 = “ as is, and the fourth line prints out the result 4, without making a new line.

(Exercise) Write a program that prints out the following text, or computes the numerical results.

1+3*5

10/3

12345*67890

“Hello, My Name is (Your Name)”

A little more detail about math expressions.

^ : Power expression: 3 ^ 2 = 3 * 3 = 9

% : Modulus (remainder) : 10 % 3 = 1

Simple program – Input

Now it’s time to learn about input. The command is, naturally, “input.” Try this simple program.

1-3 input your name

First, you instruct the user to input his name and a number. The trailing $, in the second line, means that the result is a text string. Without $ at the end, Basic256 interprets the input as a number. Now, look at the right panel. The user input his name (“Kirloy”) and his favorite number (345). His name Kirloy is stored in the variable name$, and the number is now stored in the variable number. The stored values can be verified by the print statements at lines 7 and 8.

One more tip at lines 7 and 8: the plus(+) sign applied to strings means concatenation (pasting) of strings.

In fact, the print – input pairs can be simplified to a single input statement, as follows. Simply place the prompt string before the variable, separated by comma (“,”).
