What you are trying is impossible for 2 reasons. First, INT_MAX + INT_MAX cannot be represented by an int, which is logical since the maximum value of an int is INT_MAX. This leads to an overflow. Second, even if you try to do (3 / (3 + 3)) you will get 0 since you are … Read more
Other than a few third party libraries that allow WinForms Skinning / Themeing, such as DevExpress, there isn’t much you can do. And no, you cannot use HTML and CSS, you’ll need to be developing a WinRT Win8 app to use HTML for the UI. solved How can I skin / theme a windows forms … Read more
The solution comes in three parts. Separately compile the cpp file into a .o object. I’m not going to talk about this step as I was able to use pre-compiled .o files for the third party library I was using. Apparently they were aware of the issue as well and prepared .o files for all … Read more
Its not quite clear what you are asking, in case you want the output to be in file aswell, you could try this FormatFile Function. Its reads all lines from file at once though, so be careful with bigger files. It loops through all lines then it splits that line on a whitespace character. Depending … Read more
Single question mark (?) means null check. Basically, if Console.ReadLine is null, the other part will not be implemented. In other words, Console.ReadLine()?.ToLower() is equal to this var dummy = Console.ReadLine(); if(dummy !== null) { dummy.ToLower()…. } 0 solved why you put a ? in Console.ReadLine() and ToLower() [duplicate]
You could just create a function with a return value instead.. #include <iostream> #include <optional> #include <string> using namespace std; void myFunction(optional<string> name = nullopt) { if (name == nullopt) { cout << “I wish I knew your name!” << endl; } else { cout << “Hello ” << name.value() << “!” << endl; } … Read more
to answer your specific question about knowing if its a c or c++ compiler processing your code you can look for __cplusplus standard define It’s common to see: #ifdef __cplusplus extern “C”{ ….. solved C and C++ see which compiler used for which code
Try this: public class Particle : MonoBehaviour { public static Particle instance; public float particleSize; public Transform particle; void Awake() { instance = this; } void Start() { particle.localScale *= particleSize; } } public class Magnetic : MonoBehaviour { public Transform magnetic; void Start() { magnetic.localscale *= Particle.instance.particleSize; } } 2 solved How can I … Read more
s is null after every insertion because your code s = newnode is setting the local s pointer to a new value, which does not updated the contents of the original pointer in main(). You could either have insertnode() return the s pointer (e.g., s = insertnode(s,5), not recommended), or have main() create a sentinel … Read more
You are either ignoring compiler warnings (don’t — the compiler doesn’t complain unless it spotted a bug in your code) or you aren’t compiling with enough warnings enabled (or, possibly, you are using an ancient and unhelpful C compiler). The lines you ask about are basically the same: strnset(str1, (“%s”, str1[strlen(str1)-1]), 1); The second argument … Read more
Think very carefully about the code you have for stepping through the list looking for where you can append your new value, especially the last line inside that loop body: while(nodeptr->next){ nodeptr=nodeptr->next; nodeptr->next=newNode; } Were you to actually single-step your code through a debugger, examining the list after each statement, you would see the problem … Read more
Here is the complete code. The renaming problem is gone. The renaming problem occurs if the the file is open or doesn’t exists in the directory. #include<stdio.h> #include <string.h> #include <stdlib.h> #include<inttypes.h> #include<windows.h> //Variable Declarations struct record_stu st; FILE *fp,*fp_tmp,*fp1,*f,*f1; unsigned long long int id; char Selected_Exam[255],subject[255],Exam[255],year[255]; char semester[255],Dept_name[255],username[55],username_log[55], pass1[8]; char pass2[8],pasword[10],usrname[10],ch,pasword1[10]; char usrname1[10],Course_Code[255],ss[255],s1[255] = … Read more
Try something like that: #include <stdio.h> #include <math.h> // functions shall be defined here float lift_a_car(int r1, int m1, int m2) { // note to get a float result, you need to cast to float return (r1 + (2 * (float)m1 / (m1 + m2))); } int main() { // Here you can call the … Read more
The iscntrl() function return value: A value different from zero (i.e., true) if indeed c is an alphabetic letter. Zero (i.e., false) otherwise. The isalpha() function return value: A value different from zero (i.e., true) if indeed c is a control character. Zero (i.e., false) otherwise. So, it returns non-zero value (not 1) when the … Read more
when swiping from bottom of screen, taskbar should be visible – UWP For your requirement, you need detect the taskbar‘s ManipulationDelta event, and if Cumulative.Translation.Y more than your threshold then invoke double animation to move taskbar down or up. For example private bool _isSwiped; private void StackPanel_ManipulationDelta(object sender, ManipulationDeltaRoutedEventArgs e) { if (e.IsInertial && !_isSwiped) … Read more
