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:
start with what you know
Explanation:
you can learn a lot from it
Answer:
ok!
Explanation:
Word is more for writing documents and letters, PowerPoint is used for presentations for a class work etc. Excel is a handy software that can be used to store and organize many data sets. Using its features and formulas, you can also use the tool to make sense of your data. For example, you could use a spreadsheet to track data and automatically see sums averages and totals.
