Please suggest me a way so that it can work

Don't use cin >> ques

Anonymous

If you use getline after cin>> the newline left in the input stream is read by getline

Anonymous

And it thinks it is done

Anonymous

You can fix this very easily

Anonymous

cin >> ques; string temp; getline(cin,temp);

Anonymous

This is not a very elegant fix and you should remove the cin>> itself and use getline then convert to integer internally

Anonymous

Another fix is to use cin>> everywhere instead of getline

Anonymous

And the best fix is to use a library like GNU readline to accept input safely and convert internally

Don't use cin >> ques

Thanks man

Thanks man

Also

Then the string will not store the spaces

Your code is not readable. You should format it better

Anonymous

Then the string will not store the spaces

Then you need OS specific extensions to accept input

Can tell some ways to improve it

Abhishek

Like I just also fuck up while choosing variable names

Are u kidding?

So rude...

you gotta be polite

Dima

it is not cool asking like that

Serenity

{ FILE* fp1; fp1 = fopen(argv[1], "r"); }

Serenity

Why does it throw an error ? What have I done wrong ?

Wisenky

guys , why it doesnt counts even for loop is working ??

Wisenky

Emir

odev.c:81:4: error: a label can only be part of a statement and a declaration is not a statement 81 | int secim2; | ^~~ What is my fault?

Emir

code is here

Dima

code is here

oh, wrap your case/break into a scope

Dima

case 1: { int secim2 ………. break; }

Emir

oh, wrap your case/break into a scope

so, why?

Wisenky

so, why?

got it fixed ?

Emir

got it fixed ?

yep, but i dont know why

Khoiruzi

Hi, I'm from Indonesia

Wisenky

hey @Neko_cpp would you lead me if you are available ?

Francisco

yep, but i dont know why

A switch is a unique scope. There's no different scopes for every case

what exactly is happening in these two lines? how did they be changed?

this is the output

This code is SO bad

so, do you have any ideas for my question?

Learn about differences between increment operators and how they work with pointers

Hi I need to ask something I compiled a program with SCS, how to verify it was compiled with it?

Anonymous

Assume arm64

Anonymous

Shadow call stack

Anonymous

It protects against linear and non linear buffer overflows

Anonymous

The only stable implementation is on arm64

Anonymous

It is a stronger alternative to -fstack-protector-all

Anonymous

Yeah

Anonymous

It's only supported on android 10 right now

Anonymous

Though compiler-rt provides an implementation

Anonymous

??? Are you there?

Anonymous

???

Dima

lol

Anonymous

??? Are you there?

Yeah sorry was eating

Anonymous

Well just wanted to check if the final code ends up actually using scs

Anonymous

That's all

Anonymous

I added -ffixed-x18 -fsanitize=shadow-call-stack globally in the makefile

Thats printing the integer value of the memory position that retrun from ++ step on the pointer variable One of them will be the original mem location and one of them will be the momory location + 1 So ugly code

فاطمهَ 💛

according to the videos from YouTube the last line has to be 2, 5 but the output says it's 7,5 so what did I miss?

madhu already told you. lines 5 and 6 are undefined behaviour

Anonymous

you are initialising an int * with an int (*)[4]

Anonymous

int *p = p_arr; int *q = q_arr;

فاطمهَ 💛

the program didn't say there is a mistake

Asdew

That's because you're the programmer, not the "program" or the compiler.

Anonymous

the program didn't say there is a mistake

compilers don't detect undefined behaviour. that is a consequence of being "undefined"

Anonymous

however, you can increase the warning level to get some hints about undefined behaviour in your code

Anonymous

but remember that those don't work always

Anonymous

add -Wall -Wextra -pedantic flags

Asdew

I myself also use -Werror (along with the ones Chandradeep mentioned).

فاطمهَ 💛

okay thank you

Hi

Anonymous

okay thank you

btw, since you seem to be learning the basics and not doing actual work, setting -std=c18 (instead of the gnu default) will let you stick to the international standard better. it will block GNU specific extensions to the C standard (the -pedantic flag bitches about non standard behaviour too)

Asdew

You can change c18 to your preferred version of C (I recommend C89 or C99, they're widely supported by various compilers).

if you can explain with more details that would be better because I think I'm confused with what you are saying
