Question

В чем отличие операторов write и writeln? Приведите примеры рационального использования?

Answer 1

Если ещё не поздно, то writeln после вывода осуществляет переход на новую строку, write же оставляет курсор на этой. Пример использования writeln- вывод массива столбиков, write - строкой

Answer 2

Difference between write and writeln operators

The write and writeln operators are used in programming languages like Turbo Pascal and Delphi to output data to the console or other output devices.

The main difference between the two operators is that write does not automatically move the cursor to the next line after outputting the data, while writeln does.

Here's an example to illustrate the difference:

program Example;
begin
  write('Hello, ');
  write('world!');
  writeln(' How are you?');
end.

The output of this program would be: ``` Hello, world! How are you? ```

In this example, the write operator is used to output the strings "Hello, " and "world!", while the writeln operator is used to output the string " How are you?" and move the cursor to the next line.

Rational use cases

The choice between write and writeln depends on the desired output format and the specific requirements of the program. Here are a few examples of rational use cases for each operator:

1. write: - When you want to output data without moving the cursor to the next line. This can be useful when you want to display data in a specific format or when you want to output multiple values on the same line. - For example, if you want to display a table of values with multiple columns, you can use the write operator to output each value without moving to the next line.

2. writeln: - When you want to output data and move the cursor to the next line. This is useful when you want to display data in a more readable format or when you want to separate different outputs on different lines. - For example, if you want to display a list of items, you can use the writeln operator to output each item on a separate line.

It's important to note that the choice between write and writeln depends on the specific requirements of the program and the desired output format. You can use either operator or a combination of both to achieve the desired result.
