Reading newline from previous input when reading from keyboard with scanf()

by

First scanf read the entered string and left behind \n in the input buffer. Next call to scanf read that \n and store it to character.
Try this 

scanf (" %c", &characte);   
     // ^A space before %c in scanf can skip any number of white space characters.

Program will not work for strings more than one character because scanf stops reading once find a white space character. You can use fgets instead 

 fgets(string, 200, stdin);
