What is the meaning of if I 2 == 0?

So 7 \% 3 is 1. So for if(i\%2 == 0) means every time “i” is divisible by 2 (aka even number), it returns a 0. So 0==0 would return true. So that means for each even number, enter this “if” statement.

What does I 2 == 0 mean in Java?

i \%2 == 0 is what is generally used to determine if an index is an even index. In your example this means that the even indexes for row 0 will be set to black. The other rows not equal to zero will also have every other spot being black or white. However they will be white for the even indexes.

What is the value of 0 2 in Java?

0/2=0, there is no rest, thus 0\%2=0. It means 0\%2 is different than 0.

What is a 2 == 0 in C?

n \% 2 == 0 means all the even numbers. The code inside this loop is expected to run for each even number. In c++, this operator (\%) denotes as a reminder . remainder means the remaining value of a division.

What is the output of 1/2 in Java?

When you do 1/2 that is integer division because two operands are integers, hence it resolves to zero (0.5 rounded down to zero). If you convert any one of them to double, you’ll get a double result.

What does N 2 mean in Java?

means the remainder of num divided by two which if something is divided by two the only remainder it could have is either 0 or 1, so its taking the remainder of dividing num by 2 and checking if it is equal to 0.

What does 0 mean in Java?

char
‘0’ is the char value of zero. When you write a string, you’re writing an array of ‘char’ datatypes which the compiler translates into ASCII values (which have a corresponding decimal number value).

What does i j mean in Java?

4. i = j–; is an assignment statement. The right-hand side is evaluated, and the resulting value is assigned to the thing on the left-hand side. In your case, that means: The value of j is read ( 2 , in that code)

What does 2 mean in code?

Other Codes Code 2 Urgent. Code 3 Emergency/lights and siren. Code 4 No further assistance is needed. Code 5 Stakeout. Code 6 Responding from a long distance.

How do you write 0 in Java?

The format() method of String class in Java 5 is the first choice. You just need to add “\%03d” to add 3 leading zeros in an Integer. Formatting instruction to String starts with “\%” and 0 is the character which is used in padding.

What does Colon do in Java?

It means one thing, it is an enhanced for loop. When you see the colon (:), read it as “in.” Thus, the loop above reads as “for each element e in elements.” Note that there is no performance penalty for using the for-each loop, even for arrays.

What is the difference between “==” and “\%” in Java?

“==” is used to check the equality of two things and in this case you are checking that the remainder on the division of “i” with 2 is 0 or not. To sum up all the crap written above, you are seeing whether the value of “i” is even number or not. ‘\%’ operator in JAVA means to perform modulus divison.

Why does J++ = J+1 when J=J+J?

Because, the j++, means increment after evaluation, and j+=x means j=j+x so the j becomes j+1 after evaluating j=j+j which is zero (the addition result is 0) after computation of this addition, the j is incremented by j++, but after that the addition result overrides the incremented j value by its value 0. look at this, let assume j=0;

What does \%2 mean in math?

The “\%” modulo is an math operator that return the remainder of repeatedly dividing the number on the right side until it cant result in a whole number. When doing \%2 this will result in a 1 if “i” is odd or 0 if it’s even. So if i is even the expression would be if (0==0), if 0 is equal to 0, which is true.

How do you use I\%2==0 in Python?

In the statement “i\%2==0”, this will do the following: Take the value of ‘i’ and divide by 2 ( the rvalue of the operator), and return the remainder. Compare the remainder against the value of 0. What this effectively does is determines if the value of ‘i’ is even.
