上排c++下排delphi

指针定义
char* p;
var p:^char;

指针成员
^.
->

赋值语句
=
:=


for 结构

for(i=1;i<100;i++)
{

}

for i:=1 to 100 do 

begin

end


循环结构
while(true)
{

}


while(true) do 
begin

end



if结构

if(tr.a1==0)
{

}


if(tr.a1=0) then
begin
 OutputDebugString('11111\n');
end;  

取地址

&  
@  addr 


数组定义

char  arry[200]
daary:array[0..200] of char;





typdef struct   record

{

} RECORD;


delphi 结构体

type  
tagPROCESSENTRY32 = record
  dwSize: DWORD;
  cntUsage: DWORD;
  th32ProcessID: DWORD;          // this process
  th32DefaultHeapID: ULONG_PTR;
  th32ModuleID: DWORD;           // associated exe
  cntThreads: DWORD;
  th32ParentProcessID: DWORD;    // this process's parent process
  pcPriClassBase: LONG;          // Base priority of process's threads
  dwFlags: DWORD;
  szExeFile: array [0..MAX_PATH - 1] of Char;    // Path
end;
