c is double, thus you cannot use the modulo operator %. Use fmod() instead. So change this: to this: As Slava mentioned, you could have used an int instead, like this: which wouldn’t require the use of fmod(). It’s important to understand that the modulo operator % works with ints. As πάντα ρέι mentioned, there … Read more
The bit shifting operators do exactly what their name implies. They shift bits. Here’s a brief (or not-so-brief) introduction to the different shift operators. The Operators >> is the arithmetic (or signed) right shift operator. >>> is the logical (or unsigned) right shift operator. << is the left shift operator, and meets the needs of … Read more
|= reads the same way as +=. is the same as where | is the bit-wise OR operator. All operators are referenced here. A bit-wise operator is used because, as is frequent, those constants enable an int to carry flags. If you look at those constants, you’ll see that they’re in powers of two : So you can use bit-wise OR to … Read more
Java does have a logical XOR operator, it is ^ (as in a ^ b). Apart from that, you can’t define new operators in Java. Edit: Here’s an example: Output: false ^ false = false false ^ true = true true ^ false = true true ^ true = false
The “&” denotes a reference instead of a pointer to an object (In your case a constant reference). The advantage of having a function such as over is that in the former case you are guaranteed that myname is non-null, since C++ does not allow NULL references. Since you are passing by reference, the object … Read more
As almost any modern language, python has Assignment Operators so they can use them every time you want to assign a value to a variable after doing some arithmetic or logical operation, both (assignment and operation)are expressed compact way in one statement….
The dot itself is not an operator, .^ is. The .^ is a pointwise¹ (i.e. element-wise) power, as .* is the pointwise product. .^ Array power. A.^B is the matrix with elements A(i,j) to the B(i,j) power. The sizes of A and B must be the same or be compatible. C.f. “Array vs. Matrix Operations”: … Read more
