convert chat** to chat*

Sorry but I don't get why you turned my values into 101 and 100

Because 11 and 100 have type “int” by default. (int) / (int) = (int) If you want to get result type as double you have to cast one or both of operands to “double”: (double) / (int) = (double) (int) / (double) = (double) (double) / (double) = (double) So double x,a,b; a=50,b=60; x= (double)11/100*a; cout << x;

I was reading some book about databases When I came across Non-volatile memory. I'm wondering what is it? and How can I use it in C?

Any good coder here in any language just wanna ask a question

you should have instead asked teh quesition

can u help bro

I was reading some book about databases When I came across Non-volatile memory. I'm wondering what is it? and How can I use it in C?

guys anyone knows what is meant by non-volatile memory? I know it is some sort of persistant memory but is it refering to the swap partition on the disk? and how to use it in C anyone can help me?

Hee everyone who know how to store data in Link List when we close program

https://pastebin.com/n6RrCLqK This is the problem: https://leetcode.com/problems/triangle the solution that i wrote and the solution i found on discussions thread on leetcode both are pretty much same but i don't understand why my solution is giving TLE

As I understand it refers to HDD/SSD and similar things, so it's memory in broad sense, I guess the main way to work with it through its file system (unless you're writing some OS/drivers/embedded software)

How about adding suffix like 50lf and 60lf ?

Are there any groups for just C?

Like... where you can ask just C and you won't ever see C++? Or what is the reason for such groups if this group exist for both?

Yes

Oh yeah. Also you can do 50.0 and 60.0 And more For example double(50) and double(60) And more #define D(a) (double)(a) D(50) and D(60) And more static inline double GetDouble(const int a){ return (double)a; } And how about library? main.cpp: #include "doubles.hpp" #include <iostream> int main(int argc, char **argv){ double x,a,b; a=50; b=60; x = GetDouble(11) / GetDouble(100) * a; std::cout << x; return 0; } doubles.hpp: #ifndef _DOUBLES_HPP #define _DOUBLES_HPP #define DBL(a) (double)(a) double GetDouble(const int); #endif doubles.cpp: #include "doubles.hpp" double GetDouble(const int arg){ return DBL(arg); } Makefile: CC = g++ CFLAGS = -O0 -Wall -ggdb PE = main default: $(PE).out $(PE).out: main.cpp doubles.o $(CC) $(CFLAGS) -o $@ $^ doubles.o: doubles.cpp doubles.hpp $(CC) $(CFLAGS) -c -o $@ $< clean: rm *.o rm *.out And here you go. $: make $: ./main.out 5.5 $:

template<typename F> concept SomeConcept = std::is_nothrow_invocable_v<F>; template <SomeConcept F> void doSomething(F&&); doSomething([] { std::cout << "Wowuuu!!!\n" });

template<typename F> concept SomeConcept = std::is_nothrow_invocable_v<F>; template <SomeConcept F> void doSomething(F&&); doSomething([] { std::cout << "Wowuuu!!!\n" });

can I pm you?

template<typename F> concept SomeConcept = std::is_nothrow_invocable_v<F>; template <SomeConcept F> void doSomething(F&&); doSomething([] { std::cout << "Wowuuu!!!\n" });

@K11M1 any ideas?

template<typename F> concept SomeConcept = std::is_nothrow_invocable_v<F>; template <SomeConcept F> void doSomething(F&&); doSomething([] { std::cout << "Wowuuu!!!\n" });

and where is the implementation of doSomething?

I made it std::is_invocable_v<F> and it works properly, errors were being caused by as you suspected, because of std::is_nothrow_invocable_v<F>

template<typename F> concept SomeConcept = std::is_nothrow_invocable_v<F>; template <SomeConcept F> void doSomething(F&&); doSomething([] { std::cout << "Wowuuu!!!\n" });

doSomething([]() noexcept { std::cout << "Wowuuu!!!\n"; });

Write a c++ program that returns two values ​​in a function?

you can only return one object

How can I return two values ​​.. or not possible?

Maybe the function that can return two kind of return value, that's possible using branch

But yeah, it's actually returning one value

How

Zamn, rip English

Like this ? int func(void) { if() return -1: else return 0; }

Like this ? int func(void) { if() return -1: else return 0; }

This my homework

Hi Devs! I would like to know your opinions using c++ for backend web development. Im creating a our roadmap and im looking for opinions.

How can I return two values ​​.. or not possible?

cout << "Write the number of the movies that you want to see them (to quit, press (q)) "; int value = 0; vector <int> num; for (int i = 0; i < 10; i++) { cin >> value; if (value != 'q') { num.push_back(value); } else break; } num. shrink_to_fit(); cout << "\n\nThank you" << user_name <<< " for being one of our clients\n"; cout << "All your tickets are in the file down below:"<<< endl; ofstream ticket ("Tickets.txt"); if (ticket.is_open()) { ticket << "Thank you" << user_name << " for being one of our clients\n\n"; for (int i = 0; i < num.size(); i++) { int v = num[i] 1; ticket<<<num [i] << ticket << movie_name[v]; ticket << endl; } }

I write only 10 to 5 then I press 'q' to quit But still print some of my arrays!!

i really suggest you to use builtin, it's fast the compiler only needs to check for OF (overflow flag) on x86 if you use the builtin https://godbolt.org/z/rMdxzz1vz
