Enhanced FOR loops in C++
In C++11, if your compiler supports it, yes it is. It’s called range-based for. It works for C style arrays and any type that has functions begin() and end() that return iterators. Example:
for-loop
While, Do While, For loops in Assembly Language (emu8086)
For-loops: For-loop in C: The same loop in 8086 assembler: That is the loop if you need to access your index (cx). If you just wanna to something 0-3=4 times but you do not need the index, this would be easier: If you just want to perform a very simple instruction a constant amount of … Read more
How can I print out C++ map values?
In C++11, you don’t need to spell out map<string, pair<string,string> >::const_iterator. You can use auto Note the use of cbegin() and cend() functions. Easier still, you can use the range-based for loop:
Fill array with random numbers within a specified range (C++)
You are using exact same integer in each initialization. for loop should be like that
What is the difference between ( for… in ) and ( for… of ) statements?
for in loops over enumerable property names of an object. for of (new in ES6) does use an object-specific iterator and loops over the values generated by that. In your example, the array iterator does yield all the values in the array (ignoring non-index properties).
Series Summation using for loop in python
Python syntax is a bit different than c. In particular, we usually use the range function to create the values for the iterator variable (this is what was in Stephen Rauch’s comment). The first argument to range is the starting value, the second is the final value (non-inclusive), and the third value is the step size (default of 1). … Read more
Error: can only iterate over an array or an instance of java.lang.Iterable
I assume Nodecollection is a com.aspose.words.NodeCollection. If you want to use the foreach syntax you better do:
Why is using “for…in” for array iteration a bad idea?
The reason is that one construct: can sometimes be totally different from the other: Also consider that JavaScript libraries might do things like this, which will affect any array you create:
How do I loop through or enumerate a JavaScript object?
You can use the for-in loop as shown by others. However, you also have to make sure that the key you get is an actual property of an object, and doesn’t come from the prototype. Here is the snippet: For-of with Object.keys() alternative: Notice the use of for-of instead of for-in, if not used it will return undefined on named … Read more
Pythonic way to combine FOR loop and IF statement
You can use generator expressions like this:
