我做的程序(PASCAL语言)
var
i:integer;
x:integer;
y:integer;
a:array[1..100]of integer;
begin
assign(output,'a.out');
rewrite(output);
randomize;
for i:=1 to 100 do
begin
x:=trunc(random*90+10);
y:=trunc(random*90+10);
writeln(x,'-',y,'=');
a[i]:=x-y;
end;
writeln;
for i:=1 to 100 do writeln(a[i]);
close(output);
end.
