Question

Pascal Почему runtime error const SIZE = 100000; var n, i, j: LongInt; a: array[1..SIZE, 1..SIZE] of Integer; begin Read (n); for i:= 1 to n do for j:= 1 to n do; a[i][j]:= 0; end.

Answer 1

For i:= 1 to n do
for j:= 1 to n do;
a[i][j]:= 0;

После второго do убери точку с запятой (;)

Answer 2

The code you provided will result in a runtime error because of the semicolon after the second "for" loop. This semicolon terminates the loop block, which means that the statement "a[i][j]:= 0;" is not executed within the loop.

To fix this, you should remove the semicolon after the second "for" loop, like this:

lessCopy code
const
  SIZE = 100000;
var
  n, i, j: LongInt;
  a: array[1..SIZE, 1..SIZE] of Integer;

begin
  Read(n);
  for i := 1 to n do
    for j := 1 to n do
      a[i][j] := 0;
end.

With this change, the code will initialize all elements of the array "a" to zero, which is the intended behavior.
