UNDOCUMENTED STRING EXAMPLE Initialize 2D array

[bigbass]

Hello

I saw that Peter solved a problem today with
string arrays
basic-converter.proboards.com/post/12817/thread


and I was wondering if we could do it with 2D array with strings

and yes it also works



change the declare to a 2D


DECLARE item[4][15] = { "one", "two", "three", "four"} TYPE char*
PRINT "get item ", item[3] FORMAT "%s%s\n"







 

'--- UNDOCUMENTED STRING EXAMPLE Initialize  array
DECLARE colour$[4] =  {"Blue", "Red", "Orange", "Yellow"} TYPE STRING
 
 
   
PRINT "------loop array------"
PRINT    

i=0
WHILE i <4
 PRINT  colour$[i]  
 INCR i
WEND




[bigbass]

here is one more that can cause unexpected problems


just want to post a simple demo that can get confusing in the mix of things

what appears to be the same may be different in the end result
when you are looking at the complete string size

I think that the array is the way to go when we have to get the complete string size

'----------------------
SUB usingPointer()
'----------------------
LOCAL str TYPE const char*
   str = "bacon"
   PRINT sizeof(str)
   PRINT str
END SUB


'----------------------
SUB usingArray()
'----------------------
DECLARE d[] = "bacon" TYPE const char
   '---the size of the string plus the nul character ending
   PRINT sizeof(d)
   PRINT d FORMAT "%s\n"
END SUB


CALL usingPointer
CALL usingArray





TERMINAL OUTPUT

4
bacon
6
bacon


if we use LEN we are ok in bacon




'----------------------
SUB usingPointer()
'----------------------
LOCAL str TYPE const char*
   str = "bacon"
   PRINT LEN(str)
   PRINT str
END SUB


'----------------------
SUB usingArray()
'----------------------
DECLARE d[] = "bacon" TYPE const char
   '---the size of the sting plus the nul character ending
   PRINT LEN(d)
   PRINT d FORMAT "%s\n"
END SUB


CALL usingPointer
CALL usingArray


TERMINAL OUTPUT

bacon
