I'm trying to fill an array with characters from a string inputted via console. I've tried the code bellow but it doesnt seem to work. I get Index out Of Range exception in the for loop part, and i didn't understand why it occured. Is the for loop range incorrect? Any insight would be greatly appreciated

            Console.WriteLine("Enter a string: ");
            var name = Console.ReadLine();

            var intoarray = new char[name.Length];
            for (var i = 0; i <= intoarray.Length; i++)
            {
                intoarray[i] = name[i];
            }
            foreach (var n in intoarray)
                Console.WriteLine(intoarray[n]);

using ToCharArray() strings can be converted into character arrays.

Console.WriteLine("Enter a string: ");
var name = Console.ReadLine();

var intoarray= name.ToCharArray();

foreach (var n in intoarray)
    Console.WriteLine(n);

if you are using foreach, you should wait for the index to behave as if you were taking the value.

Console.WriteLine(n);

filling a char array with a string? c++, cin >> array; should put the input directly into the array, which I'm guessing is what you want. Also, there's a problem in your string reversal logic  And: Unlike int or char, a string is a reference type. We initialize a char array. Example: We assign the 3 chars (in the char array) to letters. Recall that char is 2 bytes. Next we use the string () constructor. Constructor: This constructor is the same as a regular constructor such as new Form (), but we can use a lowercase first letter.

Since arrays start at 0 and you are counting inclusive of length, the last iteration will exceed the bounds. Just update the loop conditional to be less than length rather than less than or equal to..

Filling a character array with a string. - C++ Forum, I need to fill an array with a string that is input by a user. void initializeArray(​string str, char list[], int listSize) { int index; for (index = 0; index  N = strlength (str) N = 2×3 7 6 6 6 8 3. As of R2018b, string arrays are supported throughout MATLAB and MathWorks® products. Functions that accept character arrays (and cell arrays of character vectors) as inputs also accept string arrays.

I like snn bm's answer, but to answer you question directly, you're exceeding the length of the input by one. It should be:

        for (var i = 0; i <= intoarray.Length - 1; i++)

(Since strings are zero-indexed, the last character in the underlying array is always going to be in the position of arrayLength - 1.)

C Strings (Arrays vs. Pointers), Since these strings are really just arrays, we can access each character in the array using subscript notation, as in: cout << "Third char is: " << label[2] << endl;. A string is actually one-dimensional array of characters in C language. These are often used to create meaningful and readable programs. For example: The string "hello world" contains 12 characters including '\0' character which is automatically added by the compiler at the end of the string.

Java Program to fill an array of characters from user input, After getting the input, convert it to character array −char[] a = s.next(). Scanner; public class Demo { public static void main(String args[])  The elements of an array in C++ can be of any type. Arrays of floats, doubles, and longs are all possible; however, arrays of characters have particular significance. Human words and sentences can be expressed as an array of characters. An array of characters containing the name Stephen would appear as char sMyName[] = {'S', …

Here is your mistake. There are so many options to represent i < intoarray.Length.

for (var i = 0; i < intoarray.Length; i++) // original was i <= intoarray.Length in your code
{
    intoarray[i] = name[i];
}

Java.util.Arrays.fill(char[], char) Method, Arrays.fill(char[] a, char val) method assigns the specified char value to each void main(String[] args) { // initializing char array char arr[] = new char[] {'a','b','c'};  1) Creating String object by passing array name to the constructor 2) Using valueOf() method of String class. Example: This example demonstrates both the above mentioned ways of converting a char array to String. Here we have a char array ch and we have created two strings str and str1 using the char array.

Array of Pointers to Strings in C, As you can see not all strings are long enough to fill all the rows of the array, that's An array of pointers to strings is an array of character pointers where each pointer points to the first character of the string or the base address of the string. There are several ways to populate char arrays (and strings). As Arrch points out, using a char to fill an element in the array is one way. Using strcat() and memset() are others, depending on what you want to set the array to, and how much of the array you want to overwrite.

Convert character array to string in C++, Get the character array and its size. Create an empty string. Iterate through the character array. As you iterate keep on concatenating the characters we encounter  If, for some odd reason, you really want to fill your array with literal spaces, and intend to use it as a C string later: char p [ 50 ]; memset (& p, ' ', sizeof ( p )); p [ 49] = '\0'; /* Always guarantee null termination */.

Create character array of blanks - MATLAB blanks, This MATLAB function returns a 1-by-n array of space characters. Starting in R2017a, you can create strings using double quotes. str = "Due Date:" + b +  Given a string, the task is to convert this string into a character array in Java. Step 2: Create a character array of the same length as of string. Step 3: Traverse over the string to copy character at the i’th index of string to i’th index in the array. Step 4: Return or perform the operation on the character array.

Comments
  • Convert name to ToCharArray() directly.
  • also, as you start from 0, you need to stop at intoarray.Length - 1, so your for-loop should by like for (var i = 0; i < intoarray.Length; i++)
