How to keep one variable constant with other one changing with row in . . . 207 Lets say I have one cell A1, which I want to keep constant in a calculation For example, I want to calculate a value like this: =(B1+4) (A1) How do I make it so that if I drag that cell to make a calculation across cells in many rows, only the B1 value changes, while A1 always references that cell, instead of going to A2, A3, etc ?
What are magic numbers and why do some consider them bad? Symbolic Constant: When to replace? Magic: Unknown semantic Symbolic Constant -> Provides both correct semantic and correct context for use Semantic: The meaning or purpose of a thing "Create a constant, name it after the meaning, and replace the number with it " -- Martin Fowler First, magic numbers are not just numbers Any basic value can
fpga - Whats the difference between a constant and an inline constant . . . Edit: Just tried to use "Inline Constant" in a design to drive a width 1 signal Unfortunately, the way it is implemented in VHDL is it assigns using X"0" This has a width of 4, not 1 So the synthesiser errors out This can be avoided by setting "Inline Constant" to a width of a multiple of 4, and using that instead I ended up using an "Inline Utility Reduced Logic" to get down to 1 bit
c++ - What is the difference between const int*, const int * const, and . . . Exception, a starting const applies to what follows const int* is the same as int const* and means "pointer to constant int" const int* const is the same as int const* const and means "constant pointer to constant int" Edit: For the Dos and Don'ts, if this answer isn't enough, could you be more precise about what you want?
Whats the reason behind having std::integral_constant? What's the real use case of this? std::integral_constant I can understand this is a wrapper with value 2: typedef std::integral_constant lt;int, 2 gt; two_t But why not just use 2 or define a con
Why am I getting an expected constant expression error for the array . . . Because it expected a constant expression! Array dimensions in C (ignoring C99's VLAs) and C++ must be quantities known at compile-time That doesn't mean just labelled with const: they to be hard-coded into the program Use dynamic allocation or std::vector (which is a wrapper around dynamic array allocation) to determine array sizes at run-time
