In older C and C++ standards, the auto keyword simply meant automatic storage duration. As in the compiler automatically handles where the variable is stored, typically on the stack or in a registe...
What exactly does the static keyword do in C? I have seen it used in several diverse contexts: 1) As a variable outside a function: #include <stdio.h> static int x = 5; int main (void) ...
I have seen this construct quite a lot: int *p = (int*) malloc(n * sizeof(int)); Is this how it should be? What is the proper way to use malloc? I have also seen this: int *p = malloc(n * size...
Is it valid to partly allocate an object, as long as you only use the allocated part of it? #include <stdio.h> #include <stdlib.h> struct s { int i[100]; }; int main(void) {...
I have an ASP.NET Core 5 web application that provides functionality that involves file upload + rather large processing (memory consumption mainly). After each processing (with success or not) the...
Consider the following code: #include <stdio.h> int main() { int a = 5; int b; ++*(&b + 1); printf("%d\n", a); return 0; } The output is as expected: 6 ...
I get the concept of the heap sort algorithm and its like first you have a heap(ordered binary tree) then we have the Max heap which has the highest element value in the array at the top of the tre...
int arr[] = {10,123,14,14,15,16}; cout<<sizeof(arr)/sizeof(arr[0]); I was reading the article. When sizeof() is used with the data types such as int, float, char… etc it simply ret...
I was told by my professor/book that computer programs use two kinds of memory and that all variables get allocated either on the stack or on the heap. Is this true? How can I tell where a variable...
