2D character array initialization in C

Question

I am trying to build a list of strings that I need to pass to a function expecting char     How do I build this array  I want to pass in two options  each with less than 100 characters   char   options 2  100    options 0  0     test1   options 1  0     test2     This does not compile   What am I doing wrong exactly   How do I create a 2D character array in C

char   options 2  100     declares a size-2 array of size-100 arrays of pointers to pointers to char  You ll want to remove one    You ll also want to put your string literals in double quotes

C strings are enclosed in double quotes   const char  options 2  100    options 0  0     test1   options 1  0     test2     Re-reading your question and comments though I m guessing that what you really want to do is this   const char  options 2       test1    test2

I think what you originally meant to do was to make an array only of characters  not of pointers   char options 2  100    options 0  0   t   options 0  1   e   options 0  2   s   options 0  3   t   options 0  4   1   options 0  5    0       NUL termination of C string        A standard C library function which copies strings     strcpy options 1    test2      The code above shows two distinct methods of setting the character values in memory you have set aside to contain characters
