why i can't run with scanf_s?

I’m actually from a java background and everyone would throw and catch checked exceptions commonly. But in c++ not mindfully catching an exception is really an issue. But if not to use Exception totally then we’ll end up creating a lot of bool functions/methods because we’ll have to have a bool to indicate the successful/failing result, which appears not elegant...

You still can use try-catch like in Java. But if for some reason you or your team don't want to use exceptions (e.g. that common in gamedev to avoid exceptions), you can achieve this by wrapping all the external libraries calls that can throw in try-catch, and use other error handling strategies in your code, including: - returning status codes (e.g. bool or enum with statuses) - returning "special" values (e.g. if your function returns only positive integers you can use negative values to signal about error) - using custom written assertions for logical errors, usually a macro that writes an error to log and terminates the application (alternatively breaks into debugger or rise a system popup) if its condition not satisfied, and this macro usually being excluded from production builds Here's a simple example of such assertion code https://github.com/gameraccoon/hide-and-seek/blob/develop/src/Debug/Assert.h

It's NOT like in Java!

And what is different?

Excuse mee pls send basics material for c programming

https://pastebin.com/HRXE8aPV what should i learn to understand the auto Solve = [&] (auto ..) part i dont know that is happening in that "Solve" part, what "Self" is.. i have never seen it before and thus im unable to understand the code.. about how Solve is calling itself with Solve as parameter( line 40) i did study about what iota() does..but still unable to understand the code due to these advance things. thank you

Hello. I have a file that I have to encrypt and decrypt in C. What is the best and secured method to implement an algorithm for encryption and decryption. Any suggestions

Replace it with scanf()

This is lambda function, learn lambdas.

Thank you.😇

Does anyone use Python?

I have a few questions.

Which is the best book to study cpp

It is better for you to just start learning C from the very beginning once more.

someone uses BSPonMPI here?

Hello

#include <cstdio>

Someone is working on parallel algorithms here?

I have a question please

How could I use loops to type 500 number

#include <stdio.h> char *itohex(unsigned int n); int main(void) { int a; printf("input:"); scanf("%d",&a); printf("0x%s",itohex(a)); return 0; } char *itohex(unsigned int n) { static char hexstr[sizeof(n)*2+1]; char hexdigit[]="0123456789ABCDEF"; char *str=hexstr+sizeof(n)*2; *str = 0; do { *(--str)=hexdigit[n&0xf]; n>>=4; } while(n); return str; }
