Hi! :)

How can I preallocate a character array of 20 rows and columns consisting of 2 strings of varying length. The data is to be filled in this array one row at a time.

@Muazma Ali: you got two answers to your last question, not just one. Did you check them both?

@Muazma Ali: Then ask in the other thread for further explanations. Opening a new question for the same problem wastes the time of the answering persons. Therefore I close this question.
