printing an string in cross manner using c program
c,arrays,loops,for-loop,multidimensional-array
In your code, you need to change the for loop condition checking expressions, like i == lenstr and later i==0. They are not entering the loop, essentially. Instead, you can replace the whole block for(i = 0;i == lenstr;i++) { str2[i][j] = str[i]; j = j + 1; } for(i...

Javascript: Forloop Difference between i++ and (i+1)
The i++ is using post increment, so the value of the expression i++ is what the value was in the variable i before the increment. This code: if(sortedLetters[i] !== sortedLetters[i++]) return true; does the same thing as: if(sortedLetters[i] !== sortedLetters[i]) return true; i = i + 1; As x !==...
Java - allocation in enhanced for loop
No, you cannot use an enhanced for loop to initialize the elements of an array. The declared variable, here x, is a separate variable that refers to the current element in the array. It's null here because you just declared the array. You are changing x to refer to a...

Understanding the for loop in java
Basically the main difference is this line: for(int y=1; y<=x; y++) resp. for(int y=1; y<=5; y++) The number of times the loop is executed is different. Namely in the first case it is variable (so the number of 'x' increases), in the second case it is fixed (5 'x' printed...

Using sapply and ifelse : sapply(head(vv[vv>0],-1),function(y)ifelse(vv-y>0,vv-y,NA)) You loop over the positive values (you should also remove the last element), then you extract each value from the original vector.

Python For Loop Using Math Operators
Just as a loop is introduced by for, does not imply the same behaviour for different languages. Python's for loop iterates over objects. Something like the C-for loop does not exist. The C for loop (for ( <init> ; <cond> ; <update> ) <statement>, however, is actually identical to the...

Cancel last line iteration on a file

In python3, the 'for line in file' construct is represented by an iterator internally. By definition, a value that was produced from an iterator cannot be 'put back' for later use (http://www.diveintopython3.net/iterators.html). To get the desired behaviour, you need a function that chains together two iterators, such as the chain...

VHDL average of Array through for loop
arrays,for-loop,vhdl,moving-average
It's not that efficient to add up a large number of samples each clock period like that; an adder with n inputs will consume a lot of logic resource as n starts to increase. My suggestion is to implement a memory buffer for the samples, which will have as many...

How to use list comprehensions to make a dict having list of list as values

Why does my nested for-if loops load much slonger when I dont nest this? And can I possibly fix this?
c#,excel,if-statement,for-loop,nested
This happens because the chain of if-then-elses get terminated as soon as you find a positive match, while your loop goes on to try other strings. If you find the right value within the first few constant matches most of the time, the difference may be significant. Adding a break...
Continuous to discrete cut quartile in R from for loop
This question is more about being organized and neat with your data. There are many ways to do this. I would recommend separating out the data you want to bin into its own data.frame. x=dataset[, 50:60] then bin those columns into new columns by making a function with the parameters...
Why cant I refer to a random index in my 4D list, while I know it exists?
Based on your code where you're filling your 4D list: List<string> Lijst1D = new List<string>(); Lijst2D.Add(Lijst1D); Here you're creating new List<string> and adding it to parent 2D list. But Lijst1D itself doesn't contains any elements (you haven't added anything to it), so Lijst4D[0] will throw that IndexOutOfRangeException as well as...

How to remove all Objects in For Loop?
actionscript-3,for-loop,flash-cs6
Store the stars in an array when you add it. So you can refer to them later. The destroyStar-function is not best practice, because the star itself should not have the rights to change something in your main-displaylist. Better remove it directly in Main. Main public var numStars:int = 4;...

How to dynamically name my object params in this lodash loop?
javascript,loops,for-loop,lodash
You're referring to params.term as an existing array, which is why you're getting an error. Try this instead... params["term" + index] = .... That will create a property for each index instead. You can either access it with params["term1"] or... params.term1 ...
concurrent modification on arraylist
java,for-loop,arraylist,concurrentmodification
This is not how to do it, to remove elements while going through a List you use an iterator. Like that : List<ServiceRequest> targets = new ArrayList<ServiceRequest>(); for(Iterator<ServiceRequest> it = targets.iterator(); it.hasNext();) { ServiceRequest currentServReq = it.next(); if(someCondition) { it.remove(); } } And you will not get ConcurrentModificationException this way...
