[ad_1] In the vast majority of cases, I wouldn’t call using int instead of short a huge mistake (or even necessarily a mistake at all). As other people have indicated, the main difference is that an int is 4 bytes and a short is just 2. In most cases, using short instead of int is … Read more
[ad_1] CreateRemoteThread fails,maybe the lpBaseAddress in the target process is invalid,but it is allocated by the system? [ad_2] solved CreateRemoteThread fails,maybe the lpBaseAddress in the target process is invalid,but it is allocated by the system?
[ad_1] Your month comparisons are not correct. February is the 2nd month, not the 5th. As the second month, it doesn’t have 30 days (at least since I’ve been alive). You may want to swap those constants. 1 [ad_2] solved Usaco. Friday the thirteen. What is wrong with my code?
[ad_1] First line: You create a pointer variable to a char, then you initialize it to address zero (NULL pointer). Second line: you try to write a zero to the address where pointer is pointing to. Address zero is outside of your process’ writable virtual memory area, so you get a segmentation fault. [ad_2] solved … Read more
[ad_1] See Short-circuit evaluation. Essentially what’s happening is that as l++=3 which is not 0, it evaluates to True (only 0 would be False). Thus, the second part of the expression after || is not evaluated. 3 [ad_2] solved Output of the below C Code [duplicate]
[ad_1] The member function that you have defined (node(…)) is a constructor and lets the compiler know what to do when you create an object on type node. For example, in your code, you use this statement in your push function: t = new node(a, t);. Compiler has to know how to create a new … Read more
[ad_1] circleType::setRadius; double radius = circle.getRadius; The first line doesn’t do anything. The second line tries to set a variable of type double equal to a function. Perhaps you want to call these functions? This is what non-operator member function calls look like in C++: double area = circle.areaCir(radius); double circumferance = circle.circumCir(radius); circle.printCir(circumferance, area); … Read more
[ad_1] insert not inset Simple typo… Fix and them try again. Also try to post the code here instead of imaging it out. It’s easier for us. 0 [ad_2] solved Incorrect syntax near the keyword ‘into’ [closed]
[ad_1] Based on the data you’ve provided, here’s one way to do it. Please note, that this code is written and executed in LinqPad, so .Dump() only works there: var source = new List<KeyValuePair<string, string>> { new KeyValuePair<string, string>( “datetime”, “01/23/2017 01:10:30”) , new KeyValuePair<string, string>( “datetime”, “01/23/2017 10:00:00” ), new KeyValuePair<string, string>( “datetime”, “01/23/2017 … Read more
[ad_1] You are performing integer division, and therefore 8/6 is 1. If you want floating point arithmetic, you could change fn,sn and dvi to float instead of int, or you could simply cast one or both of the arguments to a float (or double). See this question for more in-depth answers. 2 [ad_2] solved I … Read more
[ad_1] To make IncreaseStudents work the way you want, you need to change two things: You need to return a value, meaning it can’t be void. And you need change the way you turn textBox3.Text into an integer. You don’t parse the whole expression, textBox3.Text + num; num is a number already. All you need … Read more
[ad_1] It is already 2, as Array/Collections (to be precise any .NET Class/reference type) are passed by reference by default. In fact the reference variable is passed by value, but behaves as if passed by reference. Why -> Consider var arr = new ArrayList(); The above statement first creates an ArrayList object and a reference … Read more
[ad_1] This uses std::for_each() because you asked for STL: #include <string.h> #include <string> #include <algorithm> void inlineConvertPackFilename(std::string& name) { std::for_each(name.begin(), name.end(), [](auto& c) { if (c == ‘\\’) { c=”https://stackoverflow.com/”; } else { c = tolower(c); } }); } int main() { static std::string filename(“C:\\FOO\\bar\\Baz.txt”); inlineConvertPackFilename(filename); return 0; } But that’s really unnecessary as you … Read more
[ad_1] Of course you can: #define S str##ing #define S_INCLUDE <S> #include <iostream> #include S_INCLUDE int main() { std::S str = “Hello world!”; std::cout << str << std::endl; } 2 [ad_2] solved Is there any way to use string in c++ without the word “string” appear in the program? [closed]
[ad_1] Using JsonConvert deserialize it to dynamic as below or create a matching class structure and deserialize it to that. using Newtonsoft.Json; ….. string json = File.ReadAllText(“data.txt”); var deserializedData = JsonConvert.DeserializeObject<dynamic>(json); Using json2csharp your classes should look like: public class Metrics { public int blocks { get; set; } public int bounce_drops { get; set; … Read more
