如何在PASCAL编程中绘制Pascal的三角形,就像我从输入中得到的那个钻石一样?
修改 我试过这个程序:
program Pascal_triangle;
var
i,j,n : integer;
A : Array[1..6,1..6] of Integer;
begin
n := 6;
for i:=1 to n do
begin
for j:=1 to i do
begin
if (j=1) or (i=j) then
begin
A[i,j]:=1;
end
else
begin
A[i,j] := A[i-1,j] + A[i-1,j-1];
end;
end;
end;
for i:=1 to n do
begin
Gotoxy(41-i,i);
for j:=1 to i do
write(A[i,j])
end;
readln;
end.
但我在gotoxy线上出错,我需要它是钻石。
答案 0 :(得分:0)

program Pascal_triangle;
var d,c,y,x,n : integer;
begin
readln(n);
writeln;
for y:=0 to n do
begin
c:=1;
for d:=0 to n - y do
begin
write(' ');
end;
for x:=0 to y do
begin
write(c);
write(' ');
c := c * (y - x) DIV (x + 1);
end;
writeln;
end;
for y:=n-1 downto 0 do
begin
c:=1;
for d:=0 to n - y do
begin
write(' ');
end;
for x:=0 to y do
begin
write(c);
write(' ');
c := c * (y - x) DIV (x + 1);
end;
writeln;
end;
readln;
end.
