problem with the 2D string

[ssharish2005]

hello guys,
i was working with some hashing problem where i was suppose to use 2D char string. but i have few problem in it. how do i initialize 2D array what i have done is

char string[10][11]= {};

this tells that its an empty string

and how do u check that this particular position is empty for example

if(strcmp(string[3]," what comes here")==0)

any help would be appriciated

1 - You have declared in essence, 10 "strings", 11 characters in length, including the null.
2 - You can check to see if a "string" is "empty" by simply doing:

if( string[ x ][ 0 ] == '\0' )

3 - You compare strings to see if they are something, by doing:

if( strcmp( string[ x ], "string to compare too" ) == 0 )

4 - You can access an individual letter of a given string by doing:

if( string[ whichstring ][ whichletter ] == whatevercharacter )

Everything in this color is of course optional.

I'd use

if(string[3][0]=='\0')

or even

if(!string[3][0])

Well it would be, if you had != as the test

Everything is optional. You just have to be asking the right question.
Notice I didn't complete anything other than 'if'. The 'then' is up to you to pencil in.
