Question

Дан двухмерный массив 3x4 случайных целых чисел. преобразовать массив следующим образом: элементы > 10 заменить на разницу номера строки и столбца, элементы ∈ [-5; 5] заменить на n строки в квадрате. полученный массив вывести!

Answer 1

var
a : array [1..3, 1..4] of integer;
i, j : integer;
begin
for i := 1 to 3 do
for j := 1 to 4 do
a[i, j] := trunc (random (30)) - 10;
for i := 1 to 3 do
for j := 1 to 4 do
if a[i, j] > 10 then a[i, j] := i - j;
for i := 1 to 3 do
for j := 1 to 4 do
if (a[i, j] <= 5) and (a[i, j] >= -5) then a[i, j] := sqr (i);
for i := 1 to 3 do
begin
for j := 1 to 4 do write (a[i, j]:4, ' ');
writeln;
end;
readln;
e

Answer 2

program P1;
uses
crt;
var
A : array[1..3] of array [1..4] of longint;
i,j : integer;
begin

clrscr;

randomize;

writeln('Massiv : ');

for i := 1 to 3 do
begin

writeln('');

for j := 1 to 4 do
begin
A[i][j] := random(15)+random(5)-random(5);

write(A[i][j]:2,' ');
end;

end;

for i := 1 to 3 do
for j := 1 to 4 do
begin

if A[i][j] > 10 then
A[i][j] := i - j;

if (A[i][j] >= -5) and (A[i][j] <= 5) then
A[i][j] := sqr(i);

end;

writeln('');
writeln('');

writeln('Itogoviy massiv : ');

for i := 1 to 3 do
begin

writeln('');

for j := 1 to 4 do
begin

write(A[i][j]:2,' ');
end;

end;

readln;
readln;

end.
