[SOLVED]easy question

[asadi.siyavash@gmail.com]

Hi, excuse me for my stupidly question,
I have a problem when I want to write middle a line it delete other word,
i.e:
"hello CCS"
when I want add "my" between hello and CCS it delete "CC" and then add my:
instead of "hello my CCS" it wrote:
"hello myS"

best regards,

CCS C uses a null terminated character array for strings. The array is created and then populated with the string. When you go to add to the middle of the array the array does not shift over automatically. Since it does not know how to shift it simply overwrites the characters in the array.

If you want to add to the middle of a string you would either need to create your own shift function or figure out a way to split the string apart and then rebuild it with your new word in the middle.

An example would be to take your "hello CCS" and add "my". First you need to expand the current array into a new larger array to make room for the new letters. To do this you would determine the length of the new word ("my" = 2 plus a space). Then create a new array with length = old array length+3. Then you need to copy each char over then skip and leave room for the new word, then copy the rest. Once you have the expanded array ("hello ---CCS") you can copy in the my and set the space ("hello my CCS").

Did that help?
