Insert String At Specified Position

Inserting string at position x of another string

var a = "I want apple";var b = " an";var position = 6;var output = [a.slice(0, position), b, a.slice(position)].join('');console.log(output);

How to insert character in a string at a specific position?

You can use the substr() function!

If u want to insert 25 inside $str="Hello From Other Side "; at the position 2!

U can do

$pos=2;
$new_string= substr($str, 0, $pos). "25" . substr($str, $pos);

and the results would be:

"He25llo From Other Side "

Insert a string at a specific index

You could prototype your own splice() into String.

Polyfill

if (!String.prototype.splice) {
    /**
     * {JSDoc}
     *
     * The splice() method changes the content of a string by removing a range of
     * characters and/or adding new characters.
     *
     * @this {String}
     * @param {number} start Index at which to start changing the string.
     * @param {number} delCount An integer indicating the number of old chars to remove.
     * @param {string} newSubStr The String that is spliced in.
     * @return {string} A new string with the spliced substring.
     */
    String.prototype.splice = function(start, delCount, newSubStr) {
        return this.slice(0, start) + newSubStr + this.slice(start + Math.abs(delCount));
    };
}

Example

String.prototype.splice = function(idx, rem, str) {    return this.slice(0, idx) + str + this.slice(idx + Math.abs(rem));};
var result = "foo baz".splice(4, 0, "bar ");
document.body.innerHTML = result; // "foo bar baz"

Insert string at specified position

$newstr = substr_replace($oldstr, $str_to_insert, $pos, 0);

http://php.net/substr_replace

In the above snippet, $pos is used in the offset argument of the function.

offset
If offset is non-negative, the replacing will begin at the
offset'th offset into string.
If offset is negative, the replacing will begin at the offset'th
character from the end of string.

How to add a string in a certain position?

No. Python Strings are immutable.

>>> s='355879ACB6'
>>> s[4:4] = '-'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'str' object does not support item assignment

It is, however, possible to create a new string that has the inserted character:

>>> s[:4] + '-' + s[4:]
'3558-79ACB6'

Insert into a certain position in a string

This should work:

string s = "MOT1-G-PRT45-100";
int index = ... // position to insert
string res = s.Insert(index, c + separator);

How to insert a character in a string at a certain position?

int j = 123456;
String x = Integer.toString(j);
x = x.substring(0, 4) + "." + x.substring(4, x.length());

Insert value into a string at a certain position?

You can't modify strings; they're immutable. You can do this instead:

txtBox.Text = txtBox.Text.Substring(0, i) + "TEXT" + txtBox.Text.Substring(i);

How to insert a string at x position in another string?

#include<cstring>
#include <iostream>
/*The following function supposes that str1 and str2 are cString (i.e)
ended by `\0` and inserts str2 in str1 at the specified position in a
newStr, then returns the new string as apointer*/

char* insertString(const char str1[ ],const char str2[ ],const int& position)
{
    int shiftedPos=position-1;
    int str2Size=strlen(str2);
    int str1Size=strlen(str1);
    int newSize=str2Size+str1Size+1;

    char* newStr=new char[newSize];
    for(int i=0; i<shiftedPos; i++) newStr[i]=str1[i];

    for(int i=0; i<str2Size; i++) newStr[shiftedPos+i]=str2[i];
    for(int i=0; i<newSize; i++) newStr[shiftedPos+str2Size+i]=str1[shiftedPos+i];

    newStr[newSize]='\0';

    return newStr;
}
int main(){
    auto str1 = "I have apple";
    auto str2 = "an ";
    std::cout<<insertString(str1,str2, 8);
    return 0;
}

Another code to perform exactly as you wanted

#include<iostream>
#include<cstring>
/*The following function supposes that str1 and str2 are cString (i.e)
ended by `\0` and that the memory allocated by str1 >= the len(str1)+len(str2)+1.
It inserts str2 in str1 at the specified position in str1*/

void insertString(char str1[ ], char str2[ ], int position)
{
    int str1Size=strlen(str1);
    int str2Size=strlen(str2);
    int newSize=str2Size+str1Size+1;
    int cppPosition=position-1;

    for(int i=str1Size; i>=cppPosition; i--) str1[i+str2Size]=str1[i];
    for(int i=0; i<str2Size; i++) str1[cppPosition+i]=str2[i];
    str1[newSize]='\0';
}
int main(){
    char str1[50]= "I have apple";
    char str2[50] = "an ";
    insertString(str1,str2, 8);
    std::cout<<str1;
    return 0;
}
