Answer:
The pseudocode (1) and (2) is as follows:
Pseudocode (1):
sum = 0
input n
while n ! = 999
if n > 0
sum+=n
Print sum
Pseudocode (2):
Input n1, n2
product = n1 * n2
Display product
Explanation:
Pseudocode (1):
sum = 0 --- Initialize sum to 0
input n --- Input a number
while n ! = 999 --- The loop is repeated until 999 is entered
if n > 0 --- Check if n is positive
sum+=n --- Compute the sum, if true
input n --- Get another input
Print sum --- Print the calculated sum
Pseudocode (2):
Input n1, n2 --- Get input for both numbers
product = n1 * n2 --- Compute their products
Display product --- Print the calculated product
