इस सवाल का पहले से ही एक उत्तर है: < / P>

मेरे पास एक साधारण टुकड़ा है उपयोगकर्ता नाम और पासवर्ड को मान्य करने के लिए कोड 

  सार्वजनिक बूलियन isValid (स्ट्रिंग यू, स्ट्रिंग पी) {if (u == "admin" & amp; amp; p == "password1") {सत्य; } और अगर (यू == "यूजर" और amp; पी == "पासवर्ड 2") {रिटर्न सच; } अन्य {वापसी झूठी; }}

मैंने इसे डिबग करने की कोशिश की है, और जब यह चलता है, तो आपके पास "admin" का मान है और p में "password1" का मान है, लेकिन यह पहली स्थिति को छोड़ देता है। मुझे कुछ ग़लत किया होगा, लेकिन मुझे पता नहीं है कि क्या हुआ

== स्ट्रिंग तुलना के लिए उपयोग नहीं किया जाना चाहिए इसके बजाय बराबर () का उपयोग करें।

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
