Template functions that don't accept default arguments require you to always pass a concrete instance. Didn't get this. Are you talking about the sort function, in contrast to priority_queue? In that case, what default arguments does priority_queue accept?

#include <queue> using namespace std; template <typename T> struct comp { bool operator()(T a, T b) { return a > b; } }; int main() { priority_queue<int, vector<int>, comp<int>> p; return 0; } How can I declare comp so that I can plug it into priority_queue's class Compare without the template argument? Like, priority_queue<int, vector<int>, greater<>> does not need greater<int> This probably falls under template specialization and I'm having trouble understanding it.

How to solve 5 variable 5 liner questions using c++

anyone with microprocessor knowledge to help me this please

1. Microcontrollers’ cannot be used instead of Microprocessors. Justify how Microcontroller cannot be used in place of microprocessor and using a microprocessor is not advised in place of a microcontroller. 2. Explain the difference between a JMP instruction and CALL instruction 3. How does the microprocessor differentiate between data and instruction? 4. How many interrupts does 8085 have, mention and explain them 5. Assume the content of memory locations 4001H is 51H and 2000H is 19H. Write instruction to subtract the contents of memory location 4001H from the memory location 2000H and place the result in memory location 4002H. 6. Write the Assembly language program to add the two Hex numbers. Both the numbers should be saved for future use. Save the sum in the accumulator. Numbers: A2H and 18H are stored in memory location 8080H and 8081 respectively 7. Write an assembly program that computes the 2’s compliment.

are those your personal questions or is it just some exam/assigment? :D

It is the assignment given to me

Great... do it then.

I meant something like this: https://pastebin.com/WLWG3Whh

but also yes, you could implement sort like this template< class RandomIt, class Compare > void mySort( RandomIt first, RandomIt last); and call it like this std::vector<int> V; mySort< std::vector<int>::iterator, std::greater<int> >(V.begin(), V.end()); but honestly that's pretty painful to write. std::sort forces you to pass the comp parameter so it's able to deduct the template type for you and prevents you from typing all the types. e.g. this is valid too, but it's hard to write and hard to read std::sort< std::vector<int>::iterator, std::greater<int> >(V.begin(), V.end(), std::greater<int>{});

There is not much advanced template magic here. Infact it is pretty simple. Since C++14, std::greater is defined like this: template< class T = void > struct greater; You can do something similar by providing a default template parameter argument for your comp struct. std::greater uses void as its default type and then specializes greater for void by defining operator() as a template function. You could do something similar as well like I have shown below: template <typename T=void> struct comp { bool operator()(const T& a, const T& b) { return a > b; } }; template<> struct comp<void> { template<typename T, typename U> bool operator()(T&& a, U&& b) { return a>b; } }; Now you can do something like: priority_queue<int, vector<int>, comp<>> q;

how can i get a string as input from a user in c?

Use gets

gimme an example

Use gets

Someone to assist me with C program that will prompt the user to enter all even number between 0 to 30 and find there sum

Someone to assist me with C program that will prompt the user to enter all even number between 0 to 30 and find there sum

#include <stdio.h> int main(void) { char name[20]; printf("Hello. What's your name?\n"); //scanf("%s", &name); - deprecated fgets(name,20,stdin); printf("Hi there, %s", name); return 0; }

I would use scanf("%19[^\n]", name) rather than fgets

sure, you could do that i guess

fgets will contain newline if user entered it with newline, i'm lazy to check if the end of string is newline or not (in case the user send EOF signal).

Hey everyone!🙌🏻

I need to bypass something on my laptop, can someone help?

I forgot the bitlocker password, and I can’t access the laptop without it

I heard it’s possible

Well that’s the problem, I haven’t got the key

No hacking or something? Or like a way

U mean ages literally or?

Ya not the first time :)

Who's know how to use #include directive in GLSL? Can't find any information

hello koi help karega ek ??

hello koi help karega ek ??

English please

but in setData1 I use the parameter and then set the value and in setData2 direct setting the value so any difference between both of function to setting the value ??

#include <iostream> using namespace std; class A { int a, b; public: void setData1(int x, int y) { a = x; b = y; } void print(void) { cout << " the value of a is : " << a << endl; cout << " the value of b is : " << b << endl; } void setData2(void) { cout << " enter the value of a : "; cin >> a; cout << " enter the value of b : "; cin >> b; } }; int main() { A aa; aa.setData1(1, 2); aa.print(); aa.setData2(); aa.print(); return 0; }

setData1 is usually a preferred way, because you can separate logic for working with console with your class logic. Also it will be easier to unit-test.
