In C, bool is not a keyword. It is a macro that expands to _Bool which again is a built in type. In C++ bool is a built in type.

Try to send ping. It is stateless.

I would rather start with a function adding two numbers called from C (then c++) in i386 and then x86 assembler...

Hey guys. I use boost::fibers in my code. But seems it block in ```boost::fibers::use_scheduling_algorithm<boost::fibers::algo::work_stealing>(
std::thread::hardware_concurrency());```. Anyone know how to fix it?

No I'm asking seriously like i like cp but I'm thinking of going into machine learning domain both are very different once uses very less amount of code and one is you know so is kt good to join machine learning

Hello, everyone, i'm having some troubles with gdb
I'm trying to run gdb in a really simple C code that just prints a name passed as an argument to the program, just like:
./main <name>
I'm running gdb using these commands:
gdb -q main
> Reading symbols from main...
disas main
>Dump of assembler code for function main:
> 0x0000000000001169 <+0>: endbr64
> 0x000000000000116d <+4>: push rbp
> 0x000000000000116e <+5>: mov rbp,rsp
.
.
.
b *0x1169
> Breakpoint 1 at 0x1169: file main.c, line 4.
run
>Warning:
>Cannot insert breakpoint 1.
>Cannot access memory at address 0x1169
And when i try to run i get this error message, anyone knows how to solve this? I was using the gdb earlier and suddenly it start to have this problem

The address 1169 even accounting for ASLR, seems too small and suspicious to be a valid address into the text area. These addresses might be relocation offsets.
Why don't you try the following sequence of commands?
gdb> b *0
gdb> r
gdb> disas
Now tell us the output you get from disas.

I was solving a problem on LeetCode,
Link : here
I got "Time limit exceeded".
I think my solution is O(n*logn)
Any ways to improve it ?
Your complexity is not O(n lg n) but it is O(m*n).
Since m and n can be 10^5, your algo may exhibit TLE.
A simple improvisation over your algorithm is to use Binary search on your potions vector instead of having to sequentially scan potions vector for each entry in spells. This would reduce your complexity to O(m lg m + n lg m).

Thanks, solved it like you suggested, using binary search.

Complexity will be O(nlog m) but not O(m lg m + n lg m)

Why memory leak here after operator<< call? Without operator<< everything is okey:

What is the difference between intermediate file and translation unit?
For a given source file, the process of compiling it generates many intermediate files and translation unit is one such intermediate file. The translation unit is the intermediate file that the C++ compiler starts working on and at this time the preprocessor has completed its work i.e. it is done with the first 4 phases of translation that is defined by the standard as mentioned here. Following this the C++ compiler does some additional work like concatenating adjacent string literals and lexical analysis of the preprocessing tokens. The output of this is what is considered a translation unit.
Apart from translation unit, there are multiple other intermediate files that are not always written to the hard disk unless you specifically direct the compiler to do so. They are usually kept in memory. Such files include assembly code, object files etc. Sometimes additional files related to Link Time Optimization may also be considered as intermediate files.
