C#

string word = "kusuma";
char c = 'u';
string newword=String.Empty;
string new_string = "x";
int i = 0;
do
{
    if (word[i] == c)
        newword += new_string;
    else
        newword += word[i];

    i++;
}
while (i < word.Length);

Console.WriteLine(newword);
Console.ReadLine();

This is homework, and we don't do homework for people.

0) Nobody working as a programmer for a living is going to do it without using Replace. The requirement is ludicrous.

1) This is such a simple programming task that you should be able to perform it without any help. If you don't learn to analyze a problem, how are you going to learn anything with regards to programming?

2) If you're going to be this lazy throughout your doubtlessly brief career, you should consider a line of work that doesn't require a lot of cerebral mobility, like applying glue to envelop flaps.

Hi,

this is one of a few methods

C#

string word = "kusuma";
char c = 'u';
string new_string = "x";
while (word.IndexOf(c) != -1)
{
   int index = word.IndexOf(c);
   word = word.Remove(index, 1); // remove one char
   word = word.Insert(index, new_string);
}

Hope it helps:)

Dave

good call. But the question seems a academic one. Using Remove and Insert functions do not fit. Using array and replacing it is what it deserves.
