The stage that precedes the implementation stage of SDLC is <u>testing</u> and it involves checking the functionality of the system.
System design involves the process of determining an overall system architecture, which typically comprises the following:
- Physical processing components.
Generally, there are seven (7) main stages in the systems development life cycle (SDLC) model and these include:
1. Planning.
2. Analysis.
3. Design.
4. Development.
5. Testing.
6. Implementation.
7. Maintenance.
From the above, we can deduce that the stage which precedes the implementation stage of SDLC is testing.
During the testing stage of SDLC, a quality assurance (QA) expert checks the system to determine whether or not it is functioning properly before it is deployed for operation, which is where the system can be used.

Si uno llega a fallar con un codigo en algun sistema puede verse afectado el dispositivo
Explanation:
Answer:
Following are the code to this question:
list_val = input()#defining a integer variable for input value
test_grades = list(map(int, list_val.split()))#defining test_grades as a list
sum_extra = -999 #defining sum_extra that holds negative integer value
sum_extra = 0#defining sum_extra that holds value
for y in range(len(test_grades)):#defining a for loop to check range of list
if(test_grades[y] > 100):# defining if block that check list value is greater then 100
sum_extra = sum_extra + (test_grades[y] - 100)#use sum_extra variable to hold extra value and add this value
print('Sum extra:', sum_extra)#print value
Output:
101 83 107 90
Sum extra: 8
Explanation:
In the above code a, "list_val" variable is declared, that uses an input method to input the values and declared a "test_grades" variable that uses a list method to add all values in the list.
In the next step, the "sum_extra" variable is declared, which holds some values and defines a for loop to check the range of the "test_grades", and define a if block, that checks list value is greater than 100. If the condition is true, it will remove the extra value, and add it into the sum_extera variable and add its value, and at the last use, print variable to print its value.
Answer:
int calculate_cost(int quantity) {
double cost = 0;
if (quantity <= 20)
cost = quantity * 23.45;
else if (quantity >= 21 && quantity <= 100)
cost = quantity * 21.11;
else if (quantity > 100)
cost = quantity * 18.75;
return cost;
}
Explanation:
Create a function called calculate_cost that takes one parameter, quantity
Initialize the cost as 0
Check the quantity using if else structure. Depending on the quantity passed, calculate the cost. For example, if the quantity is 10, the cost will be $234.5
Return the cost
