|The first response was correct. That's why there's a strlen() function.
|Now if it were as follows:
|
|char string[ 20 ];
|char *strpt = "hello";
|
|main()
|{
| printf( "%d\n", sizeof( string ) );
| printf( "%d\n", sizeof( strpt ) );
| printf( "%d\n", sizeof( "hello" ) );
|}
|
|the result would be:
|
|20
|4
|4

Unfortunately, if you'd bothered to actually run your program (as I did
on our VAX 8600) you would have noticed the actual result:
20
4
6
