And try with just cin.ignore()
I want to repetitively remind user to correct input after providing invalid data to prevent a fail state

Sure, that will also work but after wrong input the recursion doesn't work the way I want it to. It simply collects data infinitely

You ignoring 100 inputs I guess

Yes, not really needed though and yours is just efficient

But how do I fix the infinite recursion
Harsh
But how do I fix the infinite recursion
Umm, looking at code, you want infinite recursion till stack overflow?

That is just how it turned out. I simply want a recursion that allows a correction to be made and once done, moves on the the next statement if available

Use return; if input is valid
there's else that makes it the same as if there was a return
Pavel
strangely this code works for me 🤔
Anonymous
If input is valid, everything works fine, but when input is invalid, recursion occurs infinitely
Pavel
the only issue I had is replacing /n to \n
Pavel
oh, OK 😅

Guess I confused the slashes

The second if has a semi colon after ()

what is the issue?
Write a program to read three integer numbers then find and print the largest one among these numbers.
Al
logic is wrong

Fix the semi colon
Al
yes review the logic of comparisons it looks wrong

Second if part; else if(y>z)- you added a semi colon

Why are you answering your own questions?🤷♂️

how can we write a program with while loop which ask the user to enter an integer 10 times and at the end display their sums and their products, I know how can I do it inside the loop but how to do it at the end??

Do you need something other than std::cout << sum ;?

- VLA are optional and will impact your programs stability
- I don't see any reason to use conio
- commenting out code is pretty bad
- you don't check for invalid inputs
Thanks very much bro, however I wasn't sure of that part of the code, hence the reason for the comment; so that the code can run smoothly. I will like to know the meaning of "VLA".
Afosa
It's <conio.h> not "conio.h"
Thanks but "conio.h" is also allowed. It implies that the preprocessor is inform that file conio is found in the current working directory.

You shouldn't use libraries that were last updated probably before you were even born

Oh okay but once I changed it it's when the code started working

There is problem while fill method is called

Can some one explain why vector does not push_back value.
Cat
make() returns a nullptr. It needs to return "std::make_unique<std::vector<std::shared_ptr<List>>>()".

Rewrite the following expression in C ++ Code and print it. a + b + c + d + e Algebra: C ++: = (a + b + c + d + e) / 5; If the parentheses are removed, we obtain a + b + c + d + e / 5, which evaluates incorrectly as: a + b + c + d +e/5

"independent Operationing system" ?

I just opened Silberschatz and nowhere he defines the category of '(in)dependent operating systems'

There is a system only having the following:
- mutex lock
- atomic_dec/atomic_inc (atomic operations)
How we can realize rwlock using mutex lock and atomic operations (read write lock)?
I need to:
- describe count of mutex and atomic variables
- describe logic of rwlock_readlock, rwlock_writelock functions
