Totalling & Counting

How do you use totalling in a program?

Totalling involves adding up values, often in a loop
A total variable is set to 0 at the beginning of the program and then updated within a loop, such as:

Pseudocode	Python
`Total ← 0 FOR I ← 1 to 10 INPUT Num TOTAL ← TOTAL + Num NEXT I OUTPUT Total`	`total = 0 for i in range(1, 11): num = int(input("Enter a number: ")) total = total + num print("Total:", total)`

How do you use counting in a program?

Counting involves keeping track of the number of times a particular event occurs
A count variable is set to 0 and then updated within a loop, such as:

Pseudocode	Python
`Count ← 0 FOR I ← 1 to 10 INPUT Num IF Num > 5 THEN Count ← Count + 1 ENDIF NEXT I OUTPUT Count`	`count = 0 for i in range(1, 11): num = int(input("Enter a number: ")) if num > 5: count = count + 1 print("Count:", count)`

Pseudocode

Python

Count ← 0
FOR I ← 1 to 10
    INPUT Num
    IF Num > 5 
        THEN
            Count ← Count + 1
    ENDIF
NEXT I
OUTPUT Count

count = 0
for i in range(1, 11):
    num = int(input("Enter a number: "))
    if num > 5:
        count = count + 1
print("Count:", count)

Worked example

Write an algorithm using pseudocode that:

Inputs 20 numbers
Outputs how many of these numbers are greater than 50

[3]

Answer

Count ← 0
FOR x ← 1 TO 20  [1]
    INPUT Number
    IF Number > 50 
        THEN 
            Count ← Count + 1  [1]
    ENDIF
NEXT x
OUTPUT Count [1]
