#include <iostream>
using namespace std;
class MyClass {
public:
void DisplayMessage(const char *Text, unsigned int Type)
{
cout << "Message:Text=" << Text << endl;
cout << "Text=" << Type << endl;

void DisplayMessage(const char *Text, int Type)

cout << "Text=" << Type + 10 << endl;
}
};
int main() {
unsigned char value = 0;
MyClass my;
my.DisplayMessage("Hello", value);
}
why run second DisplayMessage?
what do you mean by second DisplayMessage? you initiate only once in your code
klimi
mack
I mean is the statement —my.DisplayMessage("Hello", value); will call 【 void DisplayMessage(const char *Text, int Type)】 function rather than second function that 【 void DisplayMessage(const char *Text, unsigned int Type)】 function.

you may want know Implicit rule
mack
yes, but i can't find the rule that contains from unsigned char to int or unsigned int

Jonathan
unsigned char or unsigned short can be converted to int if it can hold its entire value range, and unsigned int otherwise
mack
ok,i see, thank you!

👍Ok
Mr
Or for single linked list
You have to copy first node which will swap into a node(similar to swapping variables) and after that replace second node with first node and replace second node with the temporary node. And replace address part of first node(which was second node) with second node(which was first node).
Just Like this,
Temporary_Node=First_Node
First_Node=Second_Node
Second_Node=Temporary_Node
Free Temporary_Node
First_Node -> address = Second_Node

Hey all will u please help me in c++ I have project of calculator
Is like
Suppose I am doing the addition of the two number a+b=24 and the suppose the answer is 24 then after that from the user to ask that whether you want to continue with answer and add another digit in answer and then again add and if not then say no and continue to the next part
Read PPP 2nd ed.. Chap 6 and 7... Steep concept about token and grammar.. But it answer your question..

is there a runtime extra cost of using C++?
why some people don't like using it and prefer C?

Hi, I have a file divided into "sections" like this:
A1B2C3
//Stuff
B4V6N8
//Stuff2
M9N8B5
Let's imagine I want to cancel Stuff2, which may be several lines. Now, in my software I'll make sure the file poiner is set at the beginning of stuff 2.
Now, reading on stack Overflow I understand that the only way to do so seems to be copying everything you need on another file, then scrap the old one and so on.
Problem is: this file is HUGE, and this thing happens very often... so, I think this method is too slow and heavy for my code, is there another way to do so?
For everyone interested, here is a solution to the problem: if you are in a client server application and a client requests to cancel his message from the system, you mark the message on the backup as "not valid" (just come up with an escape sequence meaning not valid, like A1B2C3), then wait until you have a certain number of delete requests, then delete every message on the file marked as not valid. Therefore yes, the project is a little more complex, but in the end you copy paste the file just once, instead of many times

sure, you just need a compatible console and then you need to know how to control your console
Thank you, I'm new to this language. Which console do you recommend for this kind of job?

Does anybody knows how to convert this to recursion?
#include<stdio.h>
int main()

int T,N;

scanf("%d",&T);
int i,j;
for(i=0;i<T;i++){
sum=0;
scanf("%d",&N);
int A[N];

scanf("%d",&A[j]);
sum=sum+A[j];

Doesn't show any errors, so I am assume its logic error
how do you compile and run your code in vscode ?
Give those details.
mito
#cpp
#include <iostream>
class Base
{
private:
std::string uwu = "uwu";
public:
std::string func(){return uwu;}
};
class Derived: public Base
{
private:
std::string owo = "owo";
public:
std::string func(){return owo;}
};
int main()
{
Base *a = new Base();
std::cout << a->func() << std::endl;
a = new Derived();
std::cout << a->func() << std::endl;
return 0;
}
Output:
uwu
uwu
Shouldn't the second one be owo because of function overloading ?
Maybe it has something to do with the Base pointer a ?
Steven
otherwise a-> can only interpreted as Base
mito
otherwise a-> can only interpreted as Base
I assume because of Base *a;
So in which cases would function overloading work without using a virtual function ?
Steven
you need to declare a new variable other than a
Steven
Derived *b = new Derived();
