declare

I have an array of array with negative index. It is an array which has real dimensions [dim_y + 40][dim_x + 40] but the user uses the array like it has dimensions [dim_y][dim_x]. First i had global and already defined the dimensions dim_x, dim_y, so i had this int map_boundaries[dim_y + 40][dim_x + 40]; int (*map)[dim_x+40] = (int(*)[dim_x+40])&map_boundaries[20][20]; It worked fine. Now i need the dimensions dim_y and dim_x to be variable, and with this i mean that i want the array 'map' to not have fixed size but dynamic, i need to read the dim_y, dim_x from a user and the array 'map' to be

# declare score as integer score = int # declare rating as character rating = chr # write "Enter score: " # input score score = input("Enter score: ") # if score == 10 Then # set rating = "A" # endif if score == 10: rating = "A" print(rating) When I execute this code and enter "10" I get, built-in function chr, in the shell. I want it to print A, or another character depending on the score. For example if the input score was 8 or 9 it would have to read B. But, I'm trying to get past the first step first. I am new to programming, and if I can get pointed in the right direction that would help

I read that the pow(double, double) function is defined in "math.h" but I can't find its declaration. Does anybody know where this function declared? And where is it implemented in C? Reference: http://publications.gbdirect.co.uk/c_book/chapter9/maths_functions.html Quite often, an include file such as <math.h> will include other header files that actually declare the functions you would expect to see in <math.h> . The idea is that the program gets what it expects when it includes <math.h> , even if the actual function definitions are in some other header file. Finding the implementation of a

why can we do this in c? int n; scanf("%d",&n); int a[n]; I thought array is located memory during load time but seems like the above example works during runtime. Do I misunderstand any thing? can you guys help? Thanks, whacko__Cracko I thought array is *al*located memory during load time but seems like the above example works during run-time. Yes, ordinary arrays like <datatype> <Array_Name> [<size>] is allocated memory during load time it is there in C89 and also existed in C99. But in the code snippet int a[n]; is a Variable Length Array or VLA for short.VLA's in C99 are defined just like

I'm trying to create a string that is something like this string myStr = "CREATE TABLE myTable ( id text, name text )"; But I get an error: http://i.stack.imgur.com/o6MJK.png What is going on here? Olivier Jacot-Descombes Make a verbatim string by prepending an at sign ( @ ). Normal string literals can't span multiple lines. string myStr = @"CREATE TABLE myTable ( id text, name text )"; Note that within a verbatim string (introduced with a @ ) the backslash ( \ ) is no more interpreted as an escape character. This is practical for Regular expressions and file paths string verbatimString = @"C:
