Puzzle S13

Starts with

[E-4]Write a function that determines if one string starts with all the characters of another. For example, "applecart" starts with "apple", but "applecart" does not start with "apples". Every string starts with the null string. Here is a testing program:

/* Puzzle S13 -- starts with */

#include <stdio.h>
#include <stdlib.h>

int startsWith( char const *bigString, char const *start )
{
}

int main(int argc, char *argv[])
{
 char *trials[][2] =
  {
    {"abcdef", "a"},
    {"abcdef", "x"},
    {"abcdef", "ab"},
    {"abcdef", "abx"},
    {"abcdef", "abcdef"},
    {"abcdef", "f"},
    {"abcdef", "abcdefx"},
    {"abcdef", "abcdefxyz"},
    {"abcdef", "fooey"},
    {"abcdef", "rats"},
    {"aaaaaa", "a"},
    {"abcdefg", "g"},
    {"applecart", "apple"},
    {"green", "apple"},
    {"apple", ""},
    {"", "rats"},
    {"",""}
  };

  int j;
  for ( j=0; j<sizeof(trials)/sizeof(trials[0]); j++ )
  {
    int result = startsWith( trials[j][0], trials[j][1] ) ;
    if ( result )
      printf("%s\t          starts with\t%s\n", trials[j][0], trials[j][1] );
    else
      printf("%s\t does not start  with\t%s\n", trials[j][0], trials[j][1]  );
  }

 
  return 0;
}
