Good evening pls am new here and am giving admission in to computer science I love programming am a beginner can any one guide me pls

Use YouTube bro A lot of free courses on there

Yeah I know that but I can't ask him while watching his video,, but if its practical I can asked and my answers will be given immediately

Guide you about what?

So when you hit any barriers then you ask in this group I think that’s what the group is for

You end up summing the ASCII values of the numeric digits in the string.

Then how should i convert string to int, in order to add them?

Take the input as string and traverse through it and add (each character -'0' ) to the result.

How would i add it without typecasting it to int? And if i typecast it, it adds up it's ASCII values as Madhu said.

run a loop then use a condition to check if the number is even or not using modulus/remainder operator

I can do everything. They only think which i need it's just the way that the odd numbers going out of the loop. I don't know how to write this.

Using pointers, locate the int main() function in RAM and print it ?

Using pointers, locate the int main() function in RAM and print it ?

#include <iostream> using namespace std; int main() { std::cout << "Address of a main() function is : " <<&main<< std::endl; return 0; }

Is there a C++development program for writing game cheating programs? We can cooperate and make a lot of money

Cout 12 numbers. From 1-12. Numbers which are division with 3 print start next to them. How can i do that? (C++)

#include <iostream> using namespace std; int main() { std::cout << "Address of a main() function is : " <<&main<< std::endl; return 0; }

what is reference on c++? i am struggling to find out what does it means

Reference is similar to a pointer, but - reference can't be nullptr - you can't reassign the address it points to, after it created - dereferencing happens automatically (you don't need to do (*myVal) to get the value, or myVal->foo to refer to a member, use myVal and myVal.foo instead)

Hello to all friends, Please guide me how I can switch from C language to C++ and write a program in Qt

There is no "easy way" to switch from an imperative language to a multiparadigm language

Hi guys! I'd like an advice: I have a server and many clients (at most, 100 clients) in my client-server application. What the app does: it's like a Facebook showcase, where people can post messages (obv it's a much simpler version!). So I want it to be as efficient as possible. Therefore, I came up with two solutions: 1) The server creates a main socket and sets it on listen. When a new connection is required, the server creates a client-reserved-socket, and a client-reserved-thread that will handle any action the client might take; 2) Without spawning a thread for each client, I create a client-reserved-socket, then wait for an action of the user. The code will use the select() function. Once a signal is perceived, the select() function will spawn a thread that will handle one task and one task only. So basically the thread is summoned whenever it's neede, does something and then it's killed by the machine. I like the second one more, as I've never used it and I'd like to try something new, but given the fact that my system expects in the worst case scenario 100 people posting stuff on the showcase and possibly a user may take the same action multiple times, I'm quite worried about the expenditure the creation of every thread will have. Yes, I know, a thread is quite easy to create and not so heavy to maintain, but consider this is done multiple times, possibly hundred of times! What do you think? Let me know! Thanks if you read this!

I know that will sound abstract, but use fibers/coroutines for connections and place all networking in it

Thank you for your answer, but I don't know this stuff. It's a college project and we never talked about things like that. Are they ard to learn?

just lock it, when accepting the incoming connections and process it queue-like that’s a good scheme

I am Currently writing a school management system using C++ Where the Teacher Can 1.Add Student 2.Search Student(using StudentID) 3.Modify Student Record 4.Delete Student I have used Structures(with an Array) to define Students... So the problem i am facing is that once i add a Student after the other, the one Program stores only the Second student rather than both. How can i make the program store many students😔?

Hello, is there a way to printf a function pointer? 🤔

Using ℅p specifier ?

no dice, it says " error: format ‘%p’ expects argument of type ‘void *’, but argument 2 has type ‘void (*)()’ [-Werror=format=] "

I think you need to pass pointer to the function pritnf("%p", &myFunc); something like this probably

I get the same error message when I do that

#include<iostream> using namespace std; int *test() { static int x[4]; for(int i=0; i<4; i++) { x[i] = i%2; } return x; } int main() { int* arr = test(); printf("%d", *(arr+3)); return 0; }

#include<iostream> using namespace std; int *test() { static int x[4]; for(int i=0; i<4; i++) { x[i] = i%2; } return x; } int main() { int* arr = test(); printf("%d", *(arr+3)); return 0; }

Anybody can tell me how it,s is 1

#include<iostream> using namespace std; int *test() { static int x[4]; for(int i=0; i<4; i++) { x[i] = i%2; } return x; } int main() { int* arr = test(); printf("%d", *(arr+3)); return 0; }

https://onlinegdb.com/uWJSUMywZ Good day, I don't understand why the value is not stored in my value using the constructor. I would be grateful for an explanation

Arrays in C [0, 1, 2, 3] = 4 elements X[0] = 0, X[1] = 1, X[2] = 0, X[3] = 1 return X print arr[3]

Afaik, all static types are implicitly initialized to zero even you don't initialized it

char a[14]={"Wrong!","January","February","March","April","May","June","July","August","September","October","November","December"};

Guys is there anything wrong with this

a must be an 2d array

a must be an 2d array

🤔why

Because an array of chars is a string An array of strings is an array of arrays of chars

#include<iostream> using namespace std; int *test() { static int x[4]; for(int i=0; i<4; i++) { x[i] = i%2; } return x; } int main() { int* arr = test(); printf("%d", *(arr+3)); return 0; }
