Question

Program algorithm; begin ReadLn(a, b, c, d); func(a+b+c+d); WriteLn(x); end. подскажите где ошибка

Answer 1

Нужно изначально объявить переменные

аbcd

если нужны дробрые то -real

целые- integer;

т.е.

program algorithm;

var a,b,c,d:integer;

Пишется под Program

Answer 2

Based on the provided code snippet, it seems you are trying to read four variables a, b, c, and d from the input, pass them to a function called func, and then print the value of x after the function call. However, there are a couple of issues with this code:

1. Variable x is not defined or assigned a value before being used in the WriteLn(x) statement.
2. The function func is called, but it's not clear from the code snippet what the function does or what its return value is.

To fix these issues, you should define the variable x and also implement the func function (if it's intended to be a custom function). Here's a corrected version of the code:

pascalCopy code
Program algorithm;
var
  a, b, c, d, x: Integer; // Define the variable 'x'

// Define the function 'func' (replace with actual implementation)
procedure func(input: Integer);
begin
  // Do something with the input parameter (if needed)
  // Example: x := input * 2;
end;

begin
  ReadLn(a, b, c, d);
  func(a + b + c + d);
  // If 'func' modifies the value of 'x', you can print it here
  WriteLn(x);
end.

Please note that I've commented out the part inside the func procedure as the actual implementation of the function is missing. You should replace that with the relevant logic you want to apply to x inside the func procedure.

Without knowing what you intend to do with the function func, I can't provide a specific implementation. But this corrected version should give you a starting point for your Pascal program.
