c# - Index out of Range exception in arrays -


i continuously getting out of range exception in code. went debug mode , found giving error zeroth index itself. appreciated. 

 namespace stringtest7     {         class program         {         static void main(string[] args)         {              input();             stargenerator();             removingwords();             console.readkey();          }          public static string [] forbiddenwords = new string [10];         public static int numberofforbiddenwords;          public static string inputvalue;          public static void input()         {             console.writeline("enter value.");             inputvalue = console.readline();             console.writeline("enter number of forbidden words.");             numberofforbiddenwords = int.parse(console.readline());             console.writeline("please enter forbidden words");             (int = 0; < numberofforbiddenwords; i++)                 forbiddenwords[i] = console.readline();         }          public static void removingwords()         {                for(int =0;i<numberofforbiddenwords;i++)             {                 for(int j = 0; j< inputvalue.length - 1; i++)                 {                         inputvalue.replace(forbiddenwords[i],                                 stargenerated[i]);                 }             }              console.writeline(inputvalue);         }          public static string [] stargenerated = new string[numberofforbiddenwords];         public static void stargenerator()         {              (int = 0; < numberofforbiddenwords; i++)                 stargenerated[i] = "";              (int k = 0; k < numberofforbiddenwords; k++)                 (int = 0; < forbiddenwords[k].length-1; i++)                     stargenerated[k] = stargenerated[k] + '*';          }      } }

the stargenerator() loops create error.

this line:

public static string [] stargenerated = new string[numberofforbiddenwords];

... executed when class initialized. happen while numberofforbiddenwords still 0, i.e. long before line executed:

numberofforbiddenwords = int.parse(console.readline());

so when call stargenerator, unless numberofforbiddenwords still 0, you're going trying access invalid indexes.

i try avoid these static variables - suspect they're confusing in terms of when initialization occurring.

javascript - Function overwritting -

is there way overwrite function or event handling in function? using addeventlistener, can have many event handlers on element want var test=document.getelementbyid("div"); test.addeventlistener("click",function(){alert("im first");},false); test.addeventlistener("click",function(){alert("im second");},false); // alerts "im first" , after "im second" but if want overwrite function/event example based on client width example this function one() { alert("first"); } function two() { alert("second"); } window.onresize = function() { var test = document.getelementbyid("div"); if (window.innerwidth > 500) { test.onclick = 1 } else { test.onclick = two; } } is possible in javascript? in case use effective little known approach. addeventlistener can accept object property handleevent event handler. in case it's easy overwr...
