string append at position c++

To append a string at a specific position in C++, you can use the insert() function from the string class. Here are the steps to follow:

  1. Declare a string variable that you want to modify and a string variable containing the string you want to append. For example:
string originalString = "Hello, world!";
string appendString = " beautiful";
  1. Determine the position at which you want to append the string. This position is represented by an index value, starting from 0. For example, if you want to append the string after the word "Hello", the position would be 5.

  2. Use the insert() function to append the string at the desired position. The function takes three arguments: the position at which to insert the string, the string to insert, and the number of characters from the string to insert. Here's the syntax:

originalString.insert(position, appendString);

In our example, to append the string after "Hello", the code would be:

originalString.insert(5, appendString);
  1. The insert() function modifies the original string in place. After calling insert(), the original string will contain the appended string at the specified position. In our example, the originalString variable will now hold the value "Hello beautiful, world!".

That's it! By following these steps, you can append a string at a specific position in C++.
