Beginners have a question to ask!!

This is the for loop, i=0, i.e. i is initialized to 0, i and then we look at the contents of the loop.

The cycle body is divided into 4 parts, if(week==7).

week=0;

If week=7 is true, execute the week=0 statement, otherwise skip it.

realday++;

realday plus 1, we know from the previous that the initial value of realday is =0, and every time this loop is executed, realday adds 1.

if(week==0||week==6)

continue;

In this if function, there is a ||This is the logical operator "or", or you can read "and", which means that as long as one of the two conditions is true, then the following statement continue, the meaning of this continue is to end the execution of the current round of loop in advance, and directly enter the loop condition, that is, the following do not care, return to the condition judgment process of the for loop.

Then the last is i++, which is to add 1 to i.

Is it clear enough?

i's restriction is daycount

if(week==7)

week=0;

It means that there are 7 days in a week, and the cycle is repeated.

if(week==0||week==6)

continue;

Indicates that Saturdays and Sundays are not counted.

realday is the actual number of calendar days.

i is used as a workday cycle condition variable to obtain the number of calendar days, e.g. to determine how many workdays there are in a month.

Let's say you're in the case of understanding the for statement.

for(i=0;irealday++;For each cycle, realday adds 1if (week==0||week==6)

continue;If week==0 or week==6 is used, the following i++ statement is not executed. Keep the cycle.

i++;

2.[中[ ] means "partial".] Indicates that a certain action or thing is biased towards a certain one.

3.[indicates "....That's it".

4.[There should be a space in between, which is two words.] [Originally, originally)] [Stone)] [Mitajima (literally)

The full text translation is: Jeju Island was originally known as Samdo Island because of its many civilizations of stones, women, and wind.

5.It means "to stand".

6.Yes. Illustrate.

7.It means "go up".

Break it down

The syntax here is [

1 All 1Solution: Add x grams of sugar.

then x (80+x) = 20%.

x=20

2.Solution: If there are x winners of the first prize, there are 2x winners of the second prize and 4x prizes of the third prize.

to list groups of inequalities.

x+2x+4x)/120≥45%,x+2x+4x)/120≤50%.

Solution 54 7 x 60 7

And because x is a positive integer, x=8

Therefore, there were 8 first prizes, 16 second prizes, and 32 third prizes.

1.Set sugar x grams.

x/x+80=20% x=20

2.There will be x first prizes. 2nd prize 2x3rd prize 4x

54<7x>60

Because x is an integer.

So x=81st prize=x=8 2nd=2x=16 3rd=3x=24

then x x + 80 = 20%.

Solution: x=20

2.There will be x first prizes. 2nd prize 2x3rd prize 4x

54<7x<60

Because x is an integer.

So x=81st prize=x=8 2nd=2x=16 3rd=3x=24

Divide by (1-20%) = 100g, 100-80 = 20g

2.There will be x first prizes, 2x second prizes, and 4x third prizes

There are 8 first prizes, 16 second prizes, and 24 third prizes.

2.The numerator and denominator are equal 18 8=2 and 1 4 2<2 and 1 4 so Master Wang's efficiency is high 4 5

The four denominator numerators are the same.

Master Wang's fifth.

Four out of five.
