Hi guys, I am learning Qt and now I am in the first steps.
how do you think about Qt software?
Do you think being professional in Qt can help us to finding a job?
This group is for discussing C/C++ coding please.

Knowing as much things as possible is always a good thing. More relevant things there are in your resume the more likely it will be found by HR when they search for candidates.

hi guys , i am doing cs106b courses at stanford(2008) and couldn't connect external libraries to the project , i tried to connect them by absolute path but ide shows a bunch of errors , i googled and didn't find any solution , the problem seems to have obvious solution but as i am beginner i couldn't find it . the code #include "/Users/tigran/Desktop/cs106lib-0.3.1/headers/genlib.h"
#include "/Users/tigran/Desktop/cs106lib-0.3.1/headers/simpio.h"
#include <iostream>
int main(int argc, const char * argv[]) {
// insert code here...
std::cout << "Hello, World!\n";
return 0;
} , errors: (Main cannot be declared as global variable) , (Too many arguments provided to function-like macro invocation)

write a c program to reverse the integers(collection of digits) present in a line of text
Ex: input string 12345vector67xyz
After proccessing : 54321vector76xyz

Can anyone please tell me how to write this program?

That is an interesting exam question

You can make a loop that goes through all the symbols, then you need to remember position each time you find a digit character that follows a non-digit (startPos), and then when you find a digit character that followed by non-digit you can start anothet loop from that remembered startPos to the current pos (half that path actually) where you will swap digits

Hi can you help me h my homework?
QUESTION: Using arrays. You are given N coins in a line. The value of a coin can be either 1, 2, 5, 10, 25 or 50 . Make a program that gets the number of the coins (N), a selection factor (K), and the values of coins. Your program must calculate the sum of the coins in the positions i*K where i starts with 0 and increases by

#include <iostream>

using namespace std;

vector<double> heights = {100.3, 120.8, 132.7, 160.4, 150.3, 144.9, 170.5, 125.6};
auto myLambda = count_if(heights.begin(), heights.end(), [](int x) { return x > 125.00; });
cout << "The number of participants will be: " << myLambda;

AHMED
The output:
AHMED
The number of participants will be: 5

Why the output is not 6?

Why are you using int x as lambda argument instead of double or auto?

Hi guys. What does it mean: puts(""); ?
Just like a \n ???

What are you trying to do here? You're assigning ahmet to myobj and check in the next line ? 🤔
Your if is always true.

It prints an empty string and adds \n at the end. So yes

Hi, I can't figure out why my coroutine is leaking memory (ASan and valgrind both complains). Why..?
class A {
public:
A() { std::cerr << "A ctor\n"; }
~A() { std::cerr << "A dtor\n"; }
};
int main()
{
auto getACoro = []() -> cppcoro::task<std::shared_ptr<A>> {
co_return std::make_shared<A>();
};
auto foo = [getACoro]() -> cppcoro::task<> {
co_await getACoro();
co_return;
};
auto coro = [&foo]() -> cppcoro::task<> {
co_await foo();
};
cppcoro::sync_wait(coro());
}
Martin
Just curious, why you don't return from coro?
This is a stripped downed case of my actual bug.
Anonymous
Use have non-void return type and no (co_) return statement
Martin
You didn't answer the question
In that case. This is actually 3 or 4 layers of async coroutine calls to the network and response parser. But somehow coroutine frames aren't released when the the coroutine ends.
Pavel
This is a stripped downed case of my actual bug.
I'm not very familiar with coroutines, but if you don't return from a non-void function, this is UB, and basically anything can happen
Martin

Coroutines use co_return. Then the compiler constructs a awaiter object to be returned. There's no return statement is by design.
