2016年1月27日 · That's why when you dereference pp[0] explicitly, with *pp[0], you are dereferencing it effectively twice: First you look at the contents of the address 0x2000, which is 0x1000, and then you dereference that in order to read the memory at 0x1000.

2019年6月24日 · int *p; is a declaration of a pointer to integer. *p=0; is de-referencing the pointer, accessing the location it points at and attempting to write the value 0 there. For this to be ok, the pointer must be set to point at a valid memory location first. int *p = 0; is a declaration of a pointer to integer, with an initializer value.

2023年1月13日 · Why does Michael Sipser state that 0p0p 0 p 0 p is a bad choice for proving L = {ww|w ∈ {0, 1}∗} L = {w w | w ∈ {0, 1} ∗} is non-regular a bad choice? I feel that choice should work great for proving non - regularity of the mentioned language.

2011年8月12日 · There are several different basic numeric types, and the letters differentiate them: 0LL is a long long zero. 0x0UL is an unsigned long zero, expressed using hexadecimal notation. 0x0UL == 0UL. LL designates a literal as a long long and UL designates one as unsigned long and 0x0 is hexadecimal for 0.

Is zero to the power of zero 0, 1, or undefined? The answer reveals an important idea regarding the nature of math. Explore other common misconceptions at https://brilliant.org/zerotozero....

Zero to the power of zero, denoted as 0 0, is a mathematical expression with different interpretations depending on the context.

Signed zero is zero with an associated sign. In ordinary arithmetic, the number 0 does not have a sign, so that −0, +0 and 0 are equivalent.

2014年12月22日 · If a 64bit 0L is 8 bytes all zeros (and each byte's 8 bits are zeros), then the ~0L operation means you take all the 0 bits in those bytes and turn them to 1's. So for each byte that starts as [00000000] in bits, the result is [11111111].
