I asked OpenAi this question "can you make me a function in Harbour/ clipper language that takes the currency rates from the internet without using the access of Open Exchange Rates but of another non-paid service ?"
and gave me this answer
but i can't compile the source
- Code: Select all Expand view RUN
#include "hbapi.h"
#include "hbapierr.h"
#include "hbapiitm.h"
#include "hbstack.h"

FUNCTION GetExchangeRates( cFromCurrency, cToCurrency )
LOCAL cUrl := "https://api.exchangeratesapi.io/latest?base=" + cFromCurrency + "&symbols=" + cToCurrency
LOCAL curl := curl_easy_init()
LOCAL cResult := ""
IF curl == NIL
RETURN NIL
ENDIF
curl_easy_setopt( curl, CURLOPT_URL, cUrl )
curl_easy_setopt( curl, CURLOPT_FOLLOWLOCATION, 1 )
curl_easy_setopt( curl, CURLOPT_WRITEFUNCTION, { |buffer, size, nmemb, userp| buffer } )
curl_easy_setopt( curl, CURLOPT_WRITEDATA, @cResult )
IF curl_easy_perform( curl ) == CURLE_OK
LOCAL oJson := JsonToObj( cResult )
RETURN oJson.rates[cToCurrency]
ENDIF
curl_easy_cleanup( curl )
RETURN NIL
END FUNCTION
another questions
can you make me a function in Harbor/ clipper language that takes the currency rates from the internet without using the access of Open Exchange Rates but of another non-paid service (bank of Italy) and without using the libcurl library passing as parameter the date and the type of currency for example EUR
