pascal ";"expected but "."found
var a,t:int64;
begin readln(a);
t:=a-3500;
if t1500)and(t4500)and (t9000)and(t35000)and(t55000)and(t

var a,t:int64;
begin
      readln(a);
      t:=a-3500;
      if t<=1500 then writeln(t*0.03);
      if (t>1500)and(t<=4500) then writeln(t*0.1);
      if (t>4500)and (t<=9000) then writeln(t*0.2);
      if (t>9000)and(t<=35000) then writeln(t*0.25);
      if (t>35000)and(t<=55000) then writeln(t*0.3);
      if (t>55000)and(t<=80000) then writeln(t*0.35);
      if t>80000 then writeln(t*0.45);
End.

每一个判断语句后面执行的命令只有一条,则可以省略begin...end,如果要执行的命令超过一条则需要使用.

最后一种情况,也要使用if判断,否则,前面无论那条判断成立输出结果后,到这里都会再次输出t*0.45的结果.
