[Solved] How to store reference to Class’ property and access an instance’s property by that? [closed]

[ad_1] It looks like you’re looking for Reflection Example: public class A { int integer{get; set;} } PropertyInfo prop = typeof(A).GetProperty(“integer”); A a = new A(); prop.GetValue(a, null); prop.SetValue(a, 1234, null); You still need a reference to set/get values, but this seems about what you’re wanting. 1 [ad_2] solved How to store reference to Class’ … Read more

[Solved] Get Last element from unordered_set [closed]

[ad_1] In an unordered_set, the order of inserts does not necessarily correspond to the order that you will get when the set is iterated (hence the name “unordered”). Part of the reason why a bi-directional iterator is not supported(using a — operator) in this data structure is because being able to go backwards/forwards on an … Read more

[Solved] Get the largest, average and smallest value [closed]

[ad_1] Since you tagged this with C++, I would use std::vector objects mixed with the std::sort() algorithm for making it easy to find these stats. Here’s a simple example. #include <algorithm> #include <iostream> #include <vector> int main() { std::vector<float> numbers = { 1, 4, 3, 2 }; std::sort(numbers.begin(), numbers.end()); // numbers = { 1, 2, … Read more

[Solved] Array Code-Why Won’t it Compile?

[ad_1] You are trying to cin to a literal for some reason cin >> “Temp[1]”; Get rid of the quotes, use correct capitalization, and use the index variable i. cin >> temp[i]; 8 [ad_2] solved Array Code-Why Won’t it Compile?

[Solved] Which of these if the correct way to use seekg? [closed]

[ad_1] seekg(a, b) will set the read position to b offset by a bytes. Thus: A.seekg(0, ios::beg) is equivalent to A.seekg(0). A.seekg(0, ios::end) is equivalent to A.seekg(10) if the file is 10 bytes. A.seekg(10, ios::end) is equivalent to A.seekg(20). That won’t work with a 10-byte file. The documentation on seekg would have answered your question. … Read more

[Solved] Linux programming in C++ [closed]

[ad_1] The Unix API is C (as is the Windows API); any calls into Unix will look like C. That doesn’t stop you from using C++, however: if the function requires a char const*, for example, you can call std::string::c_str() on an std::string. Whether you want the Unix function (e.g read()) or the C++ (>> … Read more

[Solved] How to use functions in c++?

[ad_1] The part you’re missing is the return type of the function, and then to actually return that value from the function. At the moment you have void compute_sum(int limit) // compute_sum function { int sum_to_limit; sum_to_limit = limit * (limit + 1) / 2; } A function prototype in C looks pretty much like … Read more

[Solved] C language, explain this code [closed]

[ad_1] Reason for specific output. Since you don not have a break; for switch conditions you fall through all the switch cases from the first match found From this tutorial, When the variable being switched on is equal to a case, the statements following that case will execute until a break statement is reached. If … Read more

[Solved] How to exist from fscanf loop?

[ad_1] In the following statement, fscanf will return 3 if all the input operations are successful. while( fscanf(fp, “The different between frame %d and %d :%d”, &i, &j, arr) == 1 ){ Change it to: while( fscanf(fp, “The different between frame %d and %d :%d”, &i, &j, arr) == 3 ){ Another thing… You have … Read more

[Solved] C# generic inheritance and covariance part 2

[ad_1] There does not appear to be any question in this question, so I’ll make up a few questions to answer. What is a covariant conversion? Let’s suppose we have some types Fruit and Apple and Banana with the obvious relationships; Apple is a kind of Fruit, and so on. A covariant conversion is one … Read more

[Solved] C# Nested IFs OR and condition?

[ad_1] The first one would have to look at the value of process_checking twice, so performance would be (very very negligibly) worse. And of course your assumption about the “0” and “1”, the first one has to check for “1”, which is a little extra work. The real difference is readability. The second one is … Read more
