strcmp
Syntax:
  #include <string.h>
  int strcmp( const char *str1, const char *str2 );



The function strcmp() compares str1 and str2, then returns:

Return value Explanation
less than 0 str1 is less than str2
equal to 0 str1 is equal to str2
greater than 0 str1 is greater than str2

For example:

    printf( "Enter your name: " );
    scanf( "%s", name );
    if( strcmp( name, "Mary" ) == 0 )
      printf( "Hello, Dr. Mary!\n" );
