    Getchar terminating with new line or EOF

    Hi,

    I'm writing some code using the getchar function. The program should get the input character by character (using getchar) and ending when a new line character 'n' is reached or the EOF character is reached. Here's the code I worked out:

    Code:
    #include<stdio.h>
    
    int main(void)
    {
      char  c;
    
      printf("Please enter as many characters as you would like. Press enter or send
     the EOF character when you are done.\n");
    
      while( (c=getchar()) != EOF)
    
      return 0;
    }
    I know it's sloppy, but I'm a newbie so please bear with me. How can I fix this up so that I can read characters until a new line character 'n' is reached?

    Thanks

    int c;
    while ( (c=getchar()) != EOF && c != '\n' )
    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.
