Syed: IGCSE Computer Science: Program Logic

Write a program that asks the user to input a number, if the number is less than 10, it outputs the message "Too small" otherwise, "Valid".

OUTPUT ("Enter a Number")

​ (a)  

​ (b)  

OUPUT ("Too small")

​ (c)   ​

OUPUT ("Valid")

​ (d)  

• INPUT Number
• IF Number < 10 THEN
• ELSE
• ENDIF
• IF Number > 10 THEN
• IF Number == 10 THEN
• NEXT Number
• FOR Number<10 THEN

Complete the code that finds the smallest number input by the user, using the WHILE loop.

​ (a)  

Number ←1

​ (b)  

​

​ (c)  

​ (d)  

​ (e)  

ENDIF

ENDWHILE

• Minimum← 9999
• WHILE Number >=1 DO
• INPUT Number
• Minimum ← Number
• Minimum ← 0
• INPUT Minimum
• IF Number < Minimum THEN
• WHILE Minimum >=10 DO

Complete the code that finds the largest number input by the user, using the WHILE loop.

​ (a)  

Number ←1

​ (b)  

​

​ (c)  

​ (d)  

​ (e)  

ENDIF

ENDWHILE

• Max← -9999
• WHILE Number >=1 DO
• INPUT Number
• Max← Number
• INPUT Max
• IF Number >= Max THEN
• WHILE Max >=9999 DO
• Max← 9999

Complete the code that finds the average of the numbers input by a user:

​ (a)  

Total←0

Number ← 1

​ (b)  

OUTPUT("Enter a number or 0 to stop")

​

​ (c)  

​ (d)  

​ (e)  

ENDWHILE

OUTPUT (Total/Count)

• Count← 0
• INPUT Number
• Total← Total + Number
• INPUT Count
• WHILE Max >=9999 DO
• Total← Total+1
• WHILE Number >= 1 DO
• Count← Count + 1

Complete the code that checks if a number input by the user is higher than 1 and less than 10.

OUTPUT("Enter a Number between 1 and 10")

​ (a)  

​ (b)  

OUTPUT("Number is between 1 and 10.") ​

​ (c)  

OUTPUT ("Number is not between 1 and 10.")

​ (d)  

• ELSE
• IF Number >= 1 AND Number <= 10 THEN
• INPUT Number
• ENDIF
• IF Number <1 OR Number > 10 THEN
• BREAK
• ENDWHILE

Complete the code to print the first 10 natural numbers.

​ (a)  

​ (b)  

OUTPUT(i)

​ (c)  

ENDWHILE

• i ← 1
• i ← i + 1
• WHILE i <= 10 DO
• i ← 0, i ← i + 1, WHILE i < 10 DO
• WHILE i >= 10 DO
• i ← i + i,

Complete the code to display all even numbers between 1 and 20.

i ← 2

WHILE i <= 20 DO

​ (a)  

​ (b)  

ENDWHILE

• i ← i + 1
• i ← i + 2
• OUTPUT(i)
• FOR x ←0 TO 20 STEP 2

Complete the code to calculate the sum of the first 5 integers.

sum ← 0

FOR i ← 1 TO 5

​ (a)  

NEXT i

​ (b)  

• sum ← sum + i
• OUTPUT(sum)
• OUPUT(i)
• sum ← sum + sum

Complete the code to output the multiplication table of 5 up to 10.

​ (a)  

​ (b)  

OUTPUT("5 x", i, "=", product)

NEXT i

• product ← 5 * i
• FOR i ← 1 TO 10
• product ← 5 + i
• FOR i ← 0 TO 10
• product ← 5 * 10
• FOR i from -1 TO 10

Complete the code to display numbers from 20 down to 1.

​ (a)  

WHILE i >= 1
