I. Phần Trắc nghiệm (6 đ) (Khoanh tròn vào câu trả lời đúng nhất)
Câu 1: Cho x, y là hai biến nguyên và khai báo thủ
tục :
Procedure Doicho( Var a : Integer; b : Integer);
Var z : Integer;
Begin
z:=a; a:=b; b:=z;
End;
-Sau khi thực hiện các lệnh:
x:=5; y:=3;
Doicho(x, y);
thì giá trị của x, y là:
a. x=5, y=5 b. x = 3, y = 3
c. x=3, y=5 d. x=5, y=3
Câu 02: Cho khai báo đầu của một hàm:

Function F( k : Integer) : String ;
Begin
If k mod 2=0 then F:=’Chan’ else F:=’Le’;
End;
Muốn in Write( F(y) ); thì biến y phải khai
báo kiểu gì :
a) Var y : Real; b) Var y : String;
c) Var y : Integer; d) Var y : Char;
Câu 03: Khi chạy chương trình :
Var x : Integer;
Procedure TINH ;

Var y: Integer ;
Begin
y:=1; y:= y+10;
End;
BEGIN
x:=10; TINH; Write(x);
END.
-Kết quả in ra là:
a. 10 b. 12
c. 22 d. 11
Câu 04: Khi chạy chương trình :
Var x : Integer;
Procedure TTA ;
Var x : Integer;
Begin
x:= 7+5; Write(x, ‘,’);
End;
BEGIN
x:=4; TTA; Write(x:2);
END.
-Kết quả in ra là:
Câu 05. Các thao tác dùng để đọc giá trị đầu tiên trên hàng đầu từ tệp SONGUYEN.INP ra biến m
(Giả sử f là biến tệp đã khai báo)
A. Assign(f,‘SONGUYEN.INP’)->Readln(f,m)->Reset(f)->Close(f)
B. Assign(f,‘SONGUYEN.INP’)->Rewrite(f)->Writeln(f,m)->Close(f)
C. Assign(f,‘SONGUYEN.INP’)->Writeln(f,m)->Rewrite(f)->Close(f)
D. Assign(f,‘SONGUYEN.INP’)->Reset(f)->Readln(f,m)->Close(f)
Câu 06. Hàm Eof (<tên biến tệp>) trả về giá trị:
A. Sai nếu con trỏ tệp đang chỉ tới cuối dòng B. Sai nếu con trỏ tệp đang chỉ tới cuối tệp
C. Đúng nếu con trỏ tệp đang chỉ tới cuối tệp D. Đúng nếu con trỏ tệp đang chỉ tới cuối dòng

II. Phần tự luận: (4đ)
Viết chương trình nhập vào 2 số nguyên dương, xuất ra ước số chung lơn nhất và bội số chung nhỏ nhất của 2
số đó. (Có sư dụng chương trình con để tính ÚCLN)
Ví dụ: Nhập 2 số : 8 12
Kết quả -> UCLN = 4
BSCNN = 24
