विधि है - 

  निजी वर्ग DisplayNum ActionListener कार्यान्वित करता है {सार्वजनिक शून्य कार्रवाई कार्रवाई (ActionEvent e ) {IntInput = String.valueOf (सरणी []); FinalArea.setText ("\ n" + intInput); }}   
 अब समस्या  int इनपुट  लाइन के साथ है, मैं एक। वर्ग की उम्मीद कर रहा हूं और मुझे बताया गया है कि मुझे सामान्य रूप से लाइन बदलने की ज़रूरत है, लेकिन पता नहीं है कि इसे क्या करना है।   
 
 
 intInput स्ट्रिंग के रूप में घोषित किया जाना चाहिए।  
 सरणी सरणी या सरणी [0] होनी चाहिए, और इसे मुझे लगता है कि घटना से प्राप्त किया जाना चाहिए।

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.
