You need 2 tell it to :)

Hey, I started c++ as my first coding language ever. I started April 2021. I am reading from a text book c++ primer. But was told to develop a project in c++ to learn the language faster, also to have that project to show during future job interviews. Now, when I start a project, I am drown in information, and get lost, like a debugger c++ project; the syntax I found as examples to follow from, I am lost, also was told to do leetcodes , when go on there idk how to solve the problem. Now, should I just focus on the text book route? Also, I will go back to school in fall 2022 to switch major to cs

Can anyone one help me in my college project ?

What projects have u tried to make?

The only think close to a project I have done so far is input and out put I manipulate to create my own version with small iterations; which I got from the text book as examples, these are the only project

And where did u 'get lost'?

I don’t get lost in these small projects , idk if they are even projects

For starters, it is. Have u tried making an application? Maybe a small library?

No, idk how to start. I thought of making a library that hold books I have read, but idk how to even make a pop up window, when I look up how, I see some codes way out of my leagues

Thank you so much . I ever knew about winAPi

I’m looking up winapi now

I found something, win32 and c++ … now, should I concern myself if my system is 64 bit, or don’t worry about the name “win32” I’m thinking it’s 32 bit

Greetings It really matters example we have written softwares which are 32 bit and used C++ 32 bit one. In one of the product we literally translated the linux calls to winmain events and handled it in c++ 32. Some examples are Amdocs Kenan and initial version of Netcracker and Geneva iniital Billing System Cramer all were written in 32 bit Now the challenge we encountered was OS were upgraded from 32 bit machine to 64 bit machine but the software processes were still 32 bit and its memory can't be utilized more that 2 power 32. So we had to rewrite the code in c++ 64 bit version for some of the softwares. AFAIK till 2019 kenan was still in 32 bit after that I moved on.

It's UB.

It's UB.

i'm really having a hard time to find it... how can i ignore an specific char with cin? with scanf i think it is scanf("%*c"), but i can find anything like this for cin

Use getline. The character to ignore would be the last argument to getline. By default it is '\n'

i'm reading multiple lines like this: P 5 T 1 4 P 7 T 4 7 with this code: for (int i = 0; i < I; i++) { char C; int A, B; cin >> C >> A >> B; }

Ok so you mean to say that you want to ignore the first character always irrespective of what it is?

not exactly, I want to read this P's and T's to variable C

isn't that for multiple chars?

What I meant is that suppose you have a phone number in the formate 1-408-1234, you can get the individual components like this getline(cin, centre, '-'); getline(cin, area, '-'); getline(cin, phone);

Sad no ufcs will always make me sad

for (int i = 0; i < I; i++) { char C; int A, B; cin >> C >> A if (C == 'T') cin >> B; }

Sad no ufcs will always make me sad

I just read that Bjarne had been pushing for it since C++14 but it has been rejected many times

Give me static reflection and i am the 2nd happiest being alive

I actually understand why. It makes debugging harder and gives new template and argument deduction shenanigans to do, as well as making things conflict more

Yes for your case, this is how you should do it. getline or ignore won't help as you are not ignoring anything. I guess you meant to say you want to ignore input into B if C != 'T'. There is no easy way to do it in C++ AFAIK.

And as far as debugging being harder, I could argue that it makes it easier to find free functions by just using the method call notation in an IDE. So it helps with development
