Testing embedded spaces in c -

i want create function in c programming, test embedded spaces in c.

if found embedded spaces in string return 1 else 0

examples:

'sjdfnsdj' >>>>> return 0 'sdsd sdsdf' >>>>> return 1 '    ssadsa' >>> return 0 'dfjksdnf sdfsdfdf' >>>> return 1 ' sadf asdad' >>>> return 1

embedded spaces means spaces between 2 strings or after string not before string

you use strchr scan string space character after you skipped leading spaces.

assuming char buf[] holds string test

int i=0; while ( buf[i] == ' ' && buf[i] != '\0' )   i++;  return strchr( &buf[i], ' ' ) != null;

edit: post has been retagged homework.

instead of using strchr can loop 1 skip leading spaces. find out whether there further spaces after first non space char.
