I am perfectly aware, i was just demonstrating that him saying "it doesn't matter" is wrong, since the application still crashes

Ah lol, I thought you're the author My bad :)

Hello, how do you access an array composed of arrays in C?

not 2nd last i mean 2nd largest although it will be in 2nd last from array but i can't find the logic to print it in output

Size -2?

i did the same but the ans comes so weird like 555555555

If every single characters are not digits to make their value to zero for the next if else check if(toInt != 0) break; else { printf("Invalid mark. Enter again between 1-100!\n"); continue; }

Why not just write toInt = 0;

undefined reference to 'libssh2_init' who know what the problem

i alredy include_directories("/usr/local/libssh2/include")

ah, i change link_directories("/usr/local/libssh2/lib")

Yeah, but do u think it'll be safer?

first of all, when you're reading numbers, you don't have to read them as a string, copy them(?), and then pass them into atoi(), you can just pass %d as a format string into scanf also, when you're dealing with strings supplied by the user, on any more or less recent system, you're able to let scanf allocate the memory for you, by specifying either %ms or %as (look it up in the manpage on whatever system you're on)

It will make the code cleaner, because it what your line does.

Updated! Thanks for helping! Also I'll try to fix the buffer overflow using asprintf instead sprintf

Problem is very elementary

can't we use 5th line vector initilization, i can do this in array but in vector it throws error

You can use initializer_list like this: vector<int> v{{-1, 0, 1, 2, 3}}; Not sure how efficient it is when used with custom types that are expensive to move, but for ints should be fine.

There is no difference between his and your way to initialize vector. In both cases the initializer_list constructor is called.

Was the problem in sprintf? I think it was in scanf https://stackoverflow.com/questions/64368589/how-to-avoid-buffer-overflow-using-scanf

Even more specific, I'm working with CUDA, and I saw somewhere they handle error with this: #define gpuErrchk(ans) { gpuAssert((ans), __FILE__, __LINE__); } inline void gpuAssert(cudaError_t code, const char *file, int line, bool abort=true) { if (code != cudaSuccess) { fprintf(stderr,"GPUassert: %s %s %d\n", cudaGetErrorString(code), file, line); if (abort) exit(code); } } But I would like the error message to have not only the file and line but also some stack information. (Well, that didn't get specific enough) Is there any __CALLED_FROM__ or something similar that I can add to the error message?

ive got a segmentation fault on this code https://dpaste.org/UbyLg .With the debugger of replit i found out that its caused by strcpy at line 39 but idk why

Guys please help me because I don't know anything about C++ programming language

well, and we don't know anything that you might be facing because you haven't written anything

Do you know more about c++

Hi everyone, Im new to programming (C++), and would appreciate some help here. I built a program that picks 10 random integers, and I want the program should output a message if it is in non descending order, how can I do it?

check for the order of the number, if it is not in descending order, print message

Ye but I need the program to do it

well just add it to your program that picks 10 random integers

well... that's just simple if if (first <= second) {//code//}

And do I need to do that for all 10?
