Well I had to create a program to sort a bunch of string. And the user gets to choose how many strings we get to sort. Now the program works when I hard code the n, the number of strings but when I let the user do it but using scanf, the problem arises when the gets() function skips the first reading in. Here is a shot of the code and problem:

Does any know why this is happening?
put a getchar(); before starting the for loop to clear terminating newline ('\n' or ENTER ) from the input stream

thank you! it worked!
Consider it an opportunity to learn how to use fgets() to read a WHOLE line, then parse the result from memory using whatever functions you like.
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.
