    my output is weird

    Hello

    I have this as my standard input:

    Buffalo Bill's
    defunct
    who used to
    ride a watersmooth-silver
    stallion
    and break onetwothreefourfive pigeonsjustlikethat

    ( one tab on 3rd and 4th lines, 3 tabs on 5th line)



    and my cod is this:

    Code:
    #include <stdio.h>
    #include <stdlib.h>
    main(){
    
    File* fptr;
    
    int c;
    
    fptr = fopen( "poetery.out", "w");
    
    while ( getchar() != EOF )
    
         if( ( c = getchar() ) != EOF )
    
         fputc( c, fptr );
    fclose(fptr);
    return EXIT_SUCCESS;
    }
    output is:

    ufl ilsdfnt h sdt
    rd aesot-ivr tlinadbekoewtreoriepgosutieht



    can anybody explain why it does this? it's an excersize from a book, question and solution, but it doesn't explain why, and I can't figure out what is happening.

    Thank you

    each time getchar() is called it reads one character from the keyboard. Your program is calling that function twice, tossing away the character the first time. Try this fix
    Code:
    int c;
    while ( (c = getchar()) != EOF )
    {
         fputc( c, fptr );
    }
