Thank you sir or mam who ever you are.

too heavy for my pc hehehe. so i am avoided java based ide. except eclipse, i use it to generate project makefile(embedded/baremetal) and use qtcreator or vim-coc to coding hehehe.

neovim here! sometimes vscode.

I'm a man :)

What are your specs?

who can help me on c programming assigment? i can pay thank you !!!!

i5 2nd generation 12Gb ram. and slow hdd disk

Ok. It's better than mine. I have i3 2nd gen 2gb ram and 512gb hard drive.

@lightness_races_in_orbit do you know of a tool that can point out undefined behavior in C code?

There is no tool that can identify all possible Undefined Behavior use cases. But compilers do provide a suite of tools that can help to a great extent. For ex Clang has a static analyzer, address sanitizer, thread safety checker, thread sanitizer, memory sanitizer, leak sanitizer, control flow integrity checker and so on. GCC offers a similar set of tools as well. They can help identify most of the problems between them.

Thanks! I am new to Linux. Do you suggest I go with GCC/G++ or Clang/Clang++

int32_t safe_div_int32_t (int32_t a, int32_t b) { if ((b == 0) || ((a == INT32_MIN) && (b == -1))) { report_integer_math_error(); return 0; } else { return a / b; } }

What is your question here?

This uses an exit early/return early strategy, is this common in company standard coding styles or it depends on company requirements for coding standards? #edit of -> or typo

GCC is used by most of the companies. So if you learn it, it will be helpful. Clang has an amazing set of tools which would help you if you are a freelancer.

Yes it is also called fail fast strategy. Report an error where it occurs and exit early. It is mostly used to meet SLA between components. Within your own component, you must try to recover if possible.

SLA? Not familiar with this acronym.

Alright y’all I have a tricky one at least for me: #include<stdio.h> int main(): { int x = 67, *m = &x; int *n = m; char *t = n; printf(“%c %d”, *t,*n); } Apparently the answer is: C 67, not sure why though. Here’s my thinking… m is a pointer to address of x. We then copy the address of x, which is stored by m, to *n so n now points to address of x. So no m and n point to address of x. Again we copy the address but this time we copy n to *t. Since t is a char, it prints out the ASCII value of C, n is int so prints out 67. Correct?

For some reason i get compiler issue when I try to execute, that confuses me

Which compiler are you using?

I’m actually not sure. I’m using visual studio as an ide

Service Level Agreements.

I’m actually not sure. I’m using visual studio as an ide

Try your code in www.godbolt.org and choose different versions of compilers

The compile error is ‘cannot convert from ‘int *’ to ‘char *’ and value type ‘int *’ cannot be used to initialize an entity of type ‘char *’

Did you try casting it?

Not really sure what this means...

This is usually agreements on stuff like number of arguments, types of arguments, the value types representing the arguments, the return value types, whether it is an async operation or a blocking operation, the time of execution, performance metrics, HA tier and so on. These are common when you get into SOA (Services Oriented Architecture), Microservices and Component development. So in SLA, there might even be a requirement to Fail fast or Fallback recovery and so on. Depending on these, your services or components must strive to meet these requirements and when you dont it is considered a contract breach.

Casting to a char* is ok but this is implementation defined. From your example output it seems you were using a little endian system where the least significant bytes are stored first followed by the more significant bits. So when you cast this int pointer to a char pointer, the char pointer points to the byte that holds the value 67. So this is printed as 'C' because its ASCII value is 67 (assuming that is the basic character set encoding on that machine). If you tried the same program on a big Endian system, the output would be '\0' 67. This is why it is called Implementation defined. The cast though legal, still requires a casting operation to be used. The compiler wont implicitly convert a int* pointer to a char* pointer unless you tell it that it is safe to do so.

how can i play audio file in C ??

Well I want to just play a mp3 or wave file :vvv

please i need help

Be specific on which part of your code you need help with.

I just need to solve these questions

If you are stuck in the middle of solving it , you can ask.

I need help please

Is that your homework?

Have u by any chance started writing at least 1 line of code?

I did not write

If u are not even writing a single line for your own problem , why should we help u?

please please help me

Looping the word "please" wont do... FYI.

I have done a program to multiply a matrix but I can just do 5x5 × 5x5 or same but I want to do 2x3 × 3x2 how should I do that

Can I copy paste that here

You are accepting only one input n. Instead accept three inputs n,m,k and ask the user to input m*(n+k) elements instead of 2*n*n elements to form two matrices n×m and mxk matrix. Now you can display these 2 matrices with 2 for loops - the outer for loop iterating from 0 to n and the inner for loop iterating from 0 to m for the first matrix and likewise for the second matrix. Now for the multiplication, all your 3 for loop indexes range from 0 to n. You have to change it so that the first for loop ranges from 0 to n, the second from 0 to m and the third from 0 to k. You would have a n*k matrix as a result of the multiplication.

Do we have something equivalent to [DllImport("")] I have seen this in csharp samples and want to add "user32.dll" into my app

Why do some compiler uses (int main) instead of (void main )

Write a C++ application to find the mean of 1. even numbers 2. non even numbers 3.multiples of 5 from numbers between 1 and 100. Note the you are to use just a single loop and for that a single program for this task.
