Simple question: How do I insert a character into the char array buf, at say a position denoted by the variable current_position (taking domain 0 to strlen(buf))? r.

r.

1. Create a new array that is one char bigger and copy all the chars up to current_pos.
   
2. Put in the new char.
   
3. Copy the rest of the chars.

Fine, but the technicalities perplex me; I imagine it''d be something along the lines of:

I want to insert a char into caption[255];

caption[255],
buf[255], are being used without any indirection as follows:

strncpy(buf, caret_position, caption);
caption += caret_position;
strcat(buf, (char)ascii_key);
strcat(buf, caption);
strncpy(caption, strlen(buf),buf);

The problem is with caption += x - this increases the actual value of the char at its index, and I cant figure out what sort of indirection is needed to make this work. Doesn''t anybody have
some sample code that I can look at?
