Note the parenthesis to distinguish between a jagged array and a multidimensional array SubArrays can be of different length Dim jaggedArray()() As Integer = { ({1, 2, 3}), ({4, 5, 6}), ({7}) } ' jaggedArray(0) is {1, 2, 3} and so jaggedArray(0)(0) is 1 ' jaggedArray(1) is {4, 5, 6} and so jagge...

valgrind ./my-program arg1 arg2 < test-input This will run your program and produce a report of any allocations and de-allocations it did. It will also warn you about common errors like using uninitialized memory, dereferencing pointers to strange places, writing off the end of blocks allocate...

Here is a program that calls malloc but not free: #include <stdio.h> #include <stdlib.h> int main(int argc, char **argv) { char *s; s = malloc(26); // the culprint return 0; } With no extra arguments, valgrind will not look for this error. But if we turn on...

Unary folds are used to fold parameter packs over a specific operator. There are 2 kinds of unary folds: Unary Left Fold (... op pack) which expands as follows: ((Pack1 op Pack2) op ...) op PackN Unary Right Fold (pack op ...) which expands as follows: Pack1 op (... (Pack(N-1) op Pac...

Binary folds are basically unary folds, with an extra argument. There are 2 kinds of binary folds: Binary Left Fold - (value op ... op pack) - Expands as follows: (((Value op Pack1) op Pack2) op ...) op PackN Binary Right Fold (pack op ... op value) - Expands as follows: Pack1 op (......

Quantifiers allows to specify count of repeated strings. Zero or one: /a?/ Zero or many: /a*/ One or many: /a+/ Exact number: /a{2,4}/ # Two, three or four /a{2,}/ # Two or more /a{,4}/ # Less than four (including zero) By default, quantifiers are greedy, whi...

Describes ranges of symbols You can enumerate symbols explicitly /[abc]/ # 'a' or 'b' or 'c' Or use ranges /[a-z]/ # from 'a' to 'z' It is possible to combine ranges and single symbols /[a-cz]/ # 'a' or 'b' or 'c' or 'z' Leading dash (-) is treated as charachter /[-a-c]/ # '-' or 'a' o...

Unions are a specialized struct within which all members occupy overlapping memory. union U { int a; short b; float c; }; U u; //Address of a and b will be equal (void*)&u.a == (void*)&u.b; (void*)&u.a == (void*)&u.c; //Assigning to any union member changes ...

You can test if a string matches several regular expressions using a switch statement. Example case "Ruby is #1!" when /\APython/ puts "Boooo." when /\ARuby/ puts "You are right." else puts "Sorry, I didn't understand that." end This w...

Pointer initialization is a good way to avoid wild pointers. The initialization is simple and is no different from initialization of a variable. #include <stddef.h> int main() { int *p1 = NULL; char *p2 = NULL; float *p3 = NULL; /* NULL is a macro defined in st...

All versions of SharePoint are based around Sites (SPSite (SSOM) or Site (CSOM)) and Webs (SPWeb(SSOM) or Web(CSOM)). A site is not rendered in the UI although it does contain metadata and features that are applied to its children. A web is the basic building block that renders a UI to the user acce...
