c - finding an index i such that a[i] = i -

संभव डुप्लिकेट:

आपको पूर्णांक की एक सरणी वाली सरणी और सरणी की लंबाई के साथ दिया जाता है। अब आपको एक इंडेक्स i को ढूंढना होगा जैसे कि a (i) = i । यदि मैं सूचकांक दिया जाता है तो मैं ओ (लॉगन) में ऐसा करने में सक्षम हूं, लेकिन यदि सूचकांक i का उल्लेख नहीं किया गया है तो इसके बारे में क्या?

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.
