Consider: int testfunc1 (const int a) { return a; } int testfunc2 (int const a) { return a; } Are these two functions the same in every aspect or is there a difference? I'm interested in an ...

In many programs, a #define serves the same purpose as a constant. For example. #define FIELD_WIDTH 10 const int fieldWidth = 10; I commonly see the first form preferred over the other, relying on ...

I want to create a constant static array to be used throughout my Objective-C implementation file, similar to something like this at the top level of my ".m" file: static const int NUM_TYPES ...

In C, shall I prefer constants over defines? I've reading a lot of code lately, and all of the examples make heavy use of defines.

I've been told that if I'm coding in ANSI C to declare in the order that the variables will be used, assert that pointers are not null and that indices are within bounds, and to initialize just before ...

This used to work some weeks ago: template <typename T, T t> T tfunc() { return t + 10; } template <typename T> constexpr T func(T t) { return tfunc<T, t>()...

I'm having difficulties in understanding why C++ behaves in a more "relaxed" way than C when it comes to interpreting and creating types for the parameters of a function. C does the simplest thing in ...

I was asked how can a value of a const variable can be changed. My my obvious answer was "pointers!" but I tried the next piece of code and I'm puzzled... int main() { const int x = 5; int *...

Hope you all doing great! Here is what I'm trying to do - I would like to create a program which will save a string with up to 50 symbols (or less) to an array and then print out each array symbol. ...

While this compiles: char* p2c; const char* p2cc = p2c; //fine because lhs pointed type has all the qualifiers of rhs pointed type, this does not: char** p2p2c; const char** p2p2cc = p2p2c; //fail ...

The following is the method signature in a class. virtual void evaluate(const double *var, double *obj, double *constr) const = 0; virtual void evaluate(unsigned int numPoints, const double **var, ...

Take e.g. execve(2), which according to posix has this prototype [1]: int execve(const char *path, char *const argv[], char *const envp[]); To me, it seems as if int execve(const char *path, const ...
