Answer:
Branching is where a program decides whether to do something or not.
Calculate the sum of the first 5 positive odd integers: Let's do this in our head first, so we can check if our code is right or not!
The first positive 5 odd integers are: 1, 3, 5, 7, 9
Sum these to: 25
int sum = 0, k; <------These just declare our variables, telling the program 'Hey, I'm going to use 'sum' and 'k' to store data.
for (k = 1; <---We're going to repeat the following code, and we're starting at 1
k <= 10; <---- We're going to continue to repeat until we greater than 10.
k += 2) <------ Every time we do a loop, we're going to add 2.
{ sum += k; } <---- We're going to increase the number inside "sum" by the number inside "k"
Let's run this and see what happens. Remember, we keep going until we hit more than 10.
Round 0: k = nothing, sum = 0 (before we start the loop)
Round 1: k = 1, sum = 1
Round 2: k = 3, sum = 1+3 or 4
Round 3: k = 5, sum = 4 + 5 or 9
Round 4: k = 7, sum = 9 + 7 = 16
Round 5: k = 9, sum = 16 + 9 = 25
Round 6: k = 11, sum = 25 + 11 = 36
Well, we can tell here that round 5 was correct, but round 6 is not correct. And our loop condition says <=10, which means we have to do Round 6.
This means we did it one too many times. Our ending condition should be <10, instead of <=10.
Option B
Answer:
b) one needs to follow through all phases, assessment, design, deploy and manage security
Explanation:
The security life cycle is a process in which it involves the security artifacts for developing the software through a lifecycle. It contains a detailed plan that derives how to create an application form
At the time when the requirements and activity related to design is finished the next step is the software implementation. In this, the developers begins with the coding as per the requirements and designs discussed in the last step
Therefore according to the given options, the second option is correct
Answer:
Technology-enhanced
Explanation:
In the past, education was limited to classrooms and laboratories in schools, with teachers providing physical well defined resources to students. Data was also sourced physically through questionnaires and other physical methods.
In recent times and with the advancement of computers and information system, notes are taken and shared, data is mined from databases online through these technology-enhanced method of education and learning.
