    Removing subString from String

    Hi guys, I'm wondering how could I improve my code in terms of "concept" to solve the problem in optimal way and in creative concept.
    for example if I have string "that there at there" and substring is "th" then the output is removing from string the substring "th", i.e the output in this case is "at ere at ere" .
    what I'm thinking about is like this:
    I find the length of substring lets assume it's 2 in my upper example,
    and then simultaneously I run on the "string" itself which increasing and jumping i by two, whenever I arrive to char which isn't found on substring then I put it into another array , at the end I print the "another" array which I was modifying.
    I guess that's bad thinking and it's a pleasure by you guys to hear your ideas for solving my problem.

    by the way I'm not requiring to code a code instead of me, just need from ya clearing out your concept of how you solve that problem.


    thanks in advance.

    Before you come here to ask for improvements to your algorithm:
    1. Implement your algorithm.
    2. Test it thoroughly.
    3. Revise your algorithm accordingly.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    So? That is only the first step, now you need to prove your concept is correct by implementing your algorithm, testing your algorithm thoroughly, and repeating the previous steps until it is correct.

    He is so obviously a troll. How can you not see that? Why do you keep feeding him? Just let him die.

    Already solved.
    Slicing's string concept.

    I'll keep closing anything you post which is a duplicate of anything you posted in the past.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
