There are multiple issues going on here: You use strict equality === where you attempt to compare a string and a number You attempt to access .value on a non-input element, so numPage is undefined Solution: <button id=”last-page” onclick=”getNum()”>last page</button> <script> function getNum() { var numPage = document.getElementById(“page-num”).textContent; if (numPage == 1) { console.log(“matches”); } … Read more
When you use x[y] = z, it calls the __setitem__ method. i.e. x.__setitem__(y, z) In your case, CmdBtn[‘menu’] = CmdBtn.menu means CmdBtn.__setitem__(‘menu’, CmdBtn.menu) The Menubutton class does indeed provide a __setitem__ method. It looks like this is used to set a “resource value” (in this case CmdBtn.menu) for the given key (‘menu’). solved what is … Read more
First off, you are obviously gonna get 1 due to the fact there is a problem in that scanf statement. You need to remove .2 from there as @weathervane has stated. cr = scanf(“%d %.2f”,&x,&y) to this: cr = scanf(“%d %f”,&x,&y) When you print cr, you will get a value of 2 instead of 1. … Read more

It’s not very good form to bring just a requirement to Stack Overflow without obviously having tried to solve the problem yourself. Without any code there is nothing to “help” with, and I hope you’ll at least make an effort in the future Assuming there is always some whitespace before each date, this will work … Read more
Check out Custom Painting Approaches It shows the two common ways to do this: Keep an ArrayList of Objects to paint and then iterate through the List in the paintComponent() method. Paint directly to a BufferedImage and then just display the BufferedImage. solved Drawing an unknown number of shapes [closed]

You’re trying to declare one method inside another. That’s not valid in C#. You could use an anonymous function, but it would be relatively painful. Just move the Print100 method (and ideally rename it at the same time) outside Main, and call it from Main. 2 solved Recursion Code Error in c#? [closed]
This should also works… array=[“1″,”2″,”3,a”,”4,b”] for i in 0..array.length()-1 if array[i].include?(“,”) ab=array[i].split(“,”) array[i]=ab[0] end end print array #[“1″,”2″,”3″,”4”] 1 solved Splitting array and get desired elements [closed]
just use count(), $array = array(1,3,2,4,6); $a=count($array); echo $a; solved PHP : Counting how many element in an array [closed]
Edit: Okay! A switch! Let’s do it! var count = 0; for(var i = number.length; i–;){ switch(true){ case typeof number[i] == ‘number’: count++; } } alert(count); 8 solved Using a Javascript switch statement, how can I count the number of elements (numbers only) in an array? [closed]
if expressions have to be boolean. Say I have a string: string test = null; if (test) won’t compile because test is not a bool. It just returns the string reference. So, to check for null, you actually have to check for null: if (test != null) is an expression that does return a bool, … Read more
Notice the extra { void union{(int a, int b,int *p) ^ NOTE: This answer was posted before the OP edited the question to remove the typo (mentioned in this answer). Check the edits for clarity. ANOTHER NOTE: Use the standard definition of main() int main(void) //if no command line arguments. 10 solved Getting error: expected … Read more
You could use a search and test if the count is smaller then the max items and for the sum of seats. function getCombinations(array, sum, max) { function fork(i, t) { var s = t.reduce(function (r, a) { return r + a[2]; }, 0); if (s >= sum) { result.push([s, t.map(function (a) { return [a[1], … Read more
Mine’s similar to jprofitt’s but I divided them into peaks and valleys, so I can do some more stuff with it. I think his loop is much more cleaner than mine is, but I just wanted to test it out for myself.Don’t judge meeeeee This script just plots the points out and selects the peaks … Read more
