I wanted to know what's the difference of the reclaimPolicy in StorageClass vs. PersistentVolume. Currently we created multiple PersistentVolume with a StorageClass that has a reclaimPolicy of Dele...

Can we use a variable in a file using extern which is defined as both static as well as global in the base file?

Naively one could think it has, because usually auto is assumed when a storage class keyword is not supplied. Still, for file-scoped variables putting an auto in front of them gives an error. #in...

In C ,what is the use of static storage class when an external variable can serve its purpose at the same cost ie. both occupy storage space in the data segment of the executable. I have much bett...

The syntax of typedef specifier : typedef <existing_name> <alias_name> for example: typedef long unsigned int Int; It's working fine. But, If I place typedef anywhere in th...

When I do as below the code works fine : #include <stdio.h> void test( int a) { printf("a=%d\n",a); } int main() { test(10); return 1; } But when I do #include <stdio.h> void ...

I'm confused by the following piece of code: #include <iostream> using namespace std; int *foo() { //Operation } int main () { auto int ret = foo(); } I compiled the above code u...

Can the auto keyword be used as a storage class specifier in C++11? Is the following code legal in C++11? int main() { auto int x; }

I was running the following codes compiled together as: gcc A.c B.c -o combined Program A: #include<stdio.h> int a=1; int b; int main() { extern int a,b; fun(); printf("%d %d\n",a,b); } P...

Consider the following snippet: #include <iostream> template <int I> constexpr int f() { return I * f<I-1>(); } template<> constexpr int f<0>() { return 1; } int ...

When the mutable specifier is used in the declaration of a non-static data member, the data is mutable no matter whether the rest of the object is treated as const. With this fact, we may easily ha...

I was reading this and it says that the register keyword will most probably be removed from the next C++ standard. It also says that register was deprecated in 2011. So, what's wrong with reg...

As per my knowledge, segmentation for c program is: High address |---------------------------| |env/cmd line args vars | |---------------------------| | stack segment |--> uninitialized auto v...

After reading through the ANSI C Yacc grammar specification I noticed the following are all valid: register x; auto y; static z; extern q; This seems strange to me, as my understanding of type w...

Why the following doesn't compile? ... extern int i; static int i; ... but if you reverse the order, it compiles fine. ... static int i; extern int i; ... What is going on here?

I read a note in the book C How to Program 7th about some new standard C storage class named _Thread_local: The new C standard adds storage class specifier _Thread_local, which is beyond this b...

A variable declared globally is said to having program scope A variable declared globally with static keyword is said to have file scope. For example: int x = 0; // **program scope** static in...

For example, let's consider the static storage class specifier. Here are a few examples of both valid and ill-formed uses of this storage class specifier: static int a; // valid int static b; // v...

I was surprised to find that this code compiles: pure string Foo = SomePureFunction(123); pure is only mentioned in the context of functions in the online documentation. What are pure variables...
