If a is an int variable, is it always true that *&a == a ? It should be, but I can’t find a definitive statement to that effect. If p is an int* variable, is it always true that p == &*p ? Yes – in that case, neither the & nor * operators are … Read more
string aS = “ABCDEFGHI”; char ch=”C”; int idx = aS.IndexOf(ch); MessageBox.Show(string.Format(“{0} is in position {1} and between {2} and {3}”, ch.ToString(), idx + 1, aS[idx – 1], aS[idx + 1])); This wont handle if your character is at position zero and some other conditions, you’ll have to figure them out. 2 solved C# get position … Read more
C preprocessor macros simply do text replacement. They have no semantic awareness of your program. This: #include <stdio.h> #define x printf(“%s”, f); int main() { char* f = “MAIN”; printf (“Hello World”); x; return 0; } Becomes: #include <stdio.h> int main() { char* f = “MAIN”; printf (“Hello World”); printf(“%s”, f);; return 0; } Please … Read more
Here it’s done with std::sort from the header algorithm #include <iostream> #include <string> #include <algorithm> #include <vector> int main(){ std::vector<std::string> nums{ “922003001020293839297830207344987344973074734”, “766352786207892397340783784078348747606208602”, “182823068326283756515117829362376823572395775” }; std::cout << “unsorted: ” << std::endl; for (auto i : nums){ std::cout << i << std::endl; } std::sort(nums.begin(), nums.end()); //sort it std::cout << “\nsorted: ” << std::endl; for (auto i … Read more
*p1 refers to the value pointed by the pointer p1. (*p1)++ will increment the value of n by 1 and (*p2)++ will again do the increment on n, since it is pointing to the same location of p1. So the n will be incremented to 12. *p1,*p2 and n will thus have 12. So it … Read more
To answer your second part of the question, with the assumption that every round the health will decrease till 1 player hits 0. (Because the way you are implementing it now, is that every time the inner For-loop is done, you reset the health of both wizard and sorceress, therefore making this requirement useless) Declare … Read more
I think the reason why you are getting “random” numbers is because you haven’t initialized the carry variable. In the for loop, you are adding the un-initialized value of carry to the array which will cause undefined results. solved factorial giving wrong answer
I have not spent effort in trying to understand your algorithm, but at first glance it looks more complicated than it should be. From my understanding of the problem, there are 3 possibilities: the totals of the upper halves and the lower halves are already even (so nothing needs to be done) the totals of … Read more
You can use OrderBy followed by ThenBy. var result = MyCollection.OrderBy(x => x.CategoryCounter) .ThenBy(y => y.GroupCounter) .ThenBy(z => z.QuestionCounter); 1 solved Sort list on 3 values [closed]
Introduction #define is a preprocessor directive in the C programming language that allows for the definition of macros. It is used to replace a function name with a predefined value. This is useful for creating constants, as well as for creating short-hand versions of commonly used functions. By using #define, the programmer can save time … Read more
The error you’re getting is that you’re attempting to use dateCheck in it’s initial assignment, which is not allowed. In otherwords, you can’t do something like int number = number + 1; because number on the right hand side of the assignment is not assigned yet. Of course the line in question must have some … Read more
The return statement exits the method and returns the given value if the return type is other than void. The only statements in the method that are executed after a return statement are the ones in a finally block or the disposal of objects of a using-block (which essentially is a special form of try-finally): … Read more
Starting from version 1.54.0, Boost has included boost.log. solved which is best popular open source logging software/program in c++ program area? [closed]
Introduction When trying to return a bool value from a method, it is important to ensure that all local variables used in the method are assigned a value. If a local variable is used without being assigned a value, it will result in a compiler error indicating that an unassigned local variable is being used. … Read more
Introduction A function with multiple return statements is a type of function that can return multiple values. This type of function is useful when you need to return multiple values from a single function call. It can also be used to return different values depending on certain conditions. In this article, we will discuss how … Read more
