exchange of control between functions in C language -

-

निम्न परिदृश्य को ध्यान में रखते हुए:

fn (1) कॉल fn (2), फिर fn (2 ) एफ एन (3) कॉल करता है, और अब एफ एन (3) को एफएन (2) के बजाय एफएन (1) के लिए नियंत्रण देना चाहिए और नियंत्रण फिर से वापस नहीं आना चाहिए।

इसके बारे में मैंने गोटो से कोशिश की है, लेकिन गोटो फ़ंक्शंस के बीच काम नहीं करता है, इसकी केवल एक स्थानीय कूद है।

मैं जांचना चाहता हूं कि कोई और तरीका है जो मैं किसी अन्य फ़ंक्शन पर नियंत्रण भेजने के लिए इस्तेमाल कर सकता हूं

नोट: कोई वैश्विक वैरिएबल, फ़ंक्शन का सूचक इस मामले में काम करेगा

ठीक है, ऐसा करने का सामान्य तरीका होगा: 

  int fn3 () {वापसी 1; } शून्य fn2 () {यदि (fn3 ()) वापसी; ...}   
 निश्चित नहीं है कि आप कुछ अधिक विशिष्ट, जैसे setjmp / longjmp    की तलाश कर रहे हैं

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.

Python's equivalent for Ruby's define_method? -

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
