Assuming you have the number of rows “r” and the number of columns “c”, you can do this: int **arr; arr = malloc(r*sizeof(int*)); for(int i=0; i < r; i++) { arr[i] = malloc(c*sizeof(int)); } this dynamically allocates an array of pointers to integers, and then allocates arrays of integers to each pointer. Don’t forget to … Read more
The correct answer would be A Firstly it says update only those whose reference is TKY, all answers deal with that.

By using a return statement, you can return the new array that has had each element modified EDIT As per @AlexeiLevenkov’s comment, I have updated my answer to keep a count of … Read more
Both source and chars are pointers to string literals, you can’t modify a string literal, as per the language rules, the behavior of a program where this is done is undefined. source must be declared as a char array: char source[] = “hello, people.”; This way a copy of the string is stored in the … Read more
You have your string: string str = “4.29 x 4.30 x 2.58mm”; Maybe remove the mm str = str.Replace(“mm”, “”); Split them: string[] nums = str.Split(new[] { ” x ” }, StringSplitOptions.None); Round them: Math.Round(Double, Int32) Rounds a double-precision floating-point value to a specified number of fractional digits, and rounds midpoint values to the nearest … Read more
The preprocessor just performs a single pass through the file, expanding macros as it goes, and adding macros to its list when it encounters the #define. When it gets to the line typedef BLA_Str blaInstance it doesn’t yet know about the BLA_Str macro, so it leaves it unchanged in the output. You shold generally put … Read more

This is a fairly simple task: string url = @”http://google.com/adi/727412;sz=728×90;ord=$RANDOM?”; if (url.Contains(@”/adi/”)) { int pos = url.IndexOf(“;ord”); //// Find first occurence of Ord parameter url = url.Insert(pos, “;click=$CLICK”); //// Insert text at position } Edit: To accomplish the task for multiple occurences I used a solution from this thread. { string url = “<google.com/adi/727412;sz=728×90;ord=$RANDOM?>; <google.com/adi/727412;sz=300×250;ord=$RANDOM?>”; … Read more
