那位大哥或大姐说下,这里的C++是哪种编译器哦,怎么我在自己的编译器上成功运行并得到正确答案,提交后老是不能接受呢??

program Plus;

var a,b:longint;

begin

readln(a,b);

writeln(a+b);

end.

VAR A,B:LONGINT;

BEGIN

READ(A,B);

WRITELN(A+B);

END.

program aaa;

var a,b,c:longint;

begin

read(a,b);

c:=a+b;

writeln(c);

end.

Program ddd;

var a,b,c:integer;

begin readln(a,b); c:=a+b; writeln(c);

end.

var a,b,c:integer;

begin

readln (a,b);

c:=a+b;

writeln (c);

end.

哪错了???? 该死的Vaal

program xxx;

var a,b:longint;

begin

readln(a,b);

writeln(a+b);

end.

program Plus;

var a,b:longint;

begin

readln(a,b);

writeln(a+b);

end.

program plus

var a,b:longint;

begin

readln(a,b);

writeln(a+b);

end.

program plus;

var a,b:real;

begin

readln(a,b);

writeln(a,'+',b,'=',a+b)

program plus;

var a,b,c:integer;

begin

writeln(a=, ,b=);

readln(a,b);

c:=a+b;

write(c);

end.

program a1;

var a,b,c:integer;

aaaaaaaaaaa

program jisuan;

var a,b,c:longint;

begin

read(a,b);

write(c);

end.
