JSON Iterate Members

Demonstrates how to loop over the immediate members of a JSON object. Unicode C++

#include <CkJsonObjectW.h>

void ChilkatSample(void)
    {
    bool success = false;

    CkJsonObjectW json;

    const wchar_t *jsonStr = L"{ \"id\": 1, \"name\": \"A green door\", \"tags\": [\"home\", \"green\"], \"price\": 125 }";

    success = json.Load(jsonStr);
    if (success != true) {
        wprintf(L"%s\n",json.lastErrorText());
        return;
    }

    int numMembers = json.get_Size();
    int i;
    for (i = 0; i <= numMembers - 1; i++) {

        const wchar_t *name = json.nameAt(i);
        const wchar_t *value = json.stringAt(i);

        wprintf(L"%s: %s\n",name,value);

        int iValue = json.IntAt(i);
        wprintf(L"%s as integer: %d\n",name,iValue);

    }

    // Note: The StringAt method returns the value as a string regardless of the type.
    // If the value is a JSON array (such as for ["home", "green"]), then the JSON encoding
    // of the entire array is returned.

    // The IntAt method returns the value as an integer.  If the value does not convert to 
    // an integer, then 0 is returned
