我的任务要求我创建两个例程,其中一个从终端读取数据,另一个向终端输出数据,另外两个例程利用数组循环这两个例程来多次执行它们。
我遇到的问题是终端在一次运行ReadComputer
函数后崩溃而不是循环多次。编译器还向我提供以下警告:
“警告:托管类型的函数结果变量似乎未初始化”
虽然经过广泛的研究,并且由于没有人使用pascal我无法找到解决方案。任何帮助深表感谢! :)
我在这里提供了我的代码副本供参考:
program CompupterProgram;
uses TerminalUserInput;
type
Computer = Record
id: integer;
manafacturer: String;
year: integer;
warranty: integer;
end;
type Computers = Array of Computer;
function ReadComputer(): Computer;
begin
ReadComputer.id := ReadInteger('PLease Enter Computer Id:');
ReadComputer.manafacturer := ReadString('PLease Enter Computer Manafacturer:');
ReadComputer.year := ReadInteger('PLease Enter Computer Year:');
ReadComputer.warranty := ReadInteger('PLease Enter Computer Warranty:');
result := ReadComputer;
end;
procedure WriteComputer(c: Computer);
begin
WriteLn('Computer ID: ', c.id);
WriteLn('Computer Manafacturer ', c.manafacturer);
WriteLn('Computer Year ', c.year);
WriteLn('Computer Warranty ', c.warranty);
ReadLn();
end;
function ReadAllComputers(count: Integer): Computers;
var i: Integer;
begin
for i := 0 to count do
begin
ReadAllComputers[i] := ReadComputer();
end;
result := ReadAllComputers;
end;
procedure WriteAllComputers(computerArray: Computers);
var i: Integer;
begin
for i:= 0 to (length(computerArray)) do
begin
WriteComputer(computerArray[i]);
end;
end;
procedure Main();
var computers: Array of Computer;
index: Integer;
begin
computers := ReadAllComputers(3);
WriteAllComputers(computers);
end;
begin
Main();
end.
