you cant make it infinite, but you can restructure this so it looks nicer
make a map where you parse an integer value to a string name
#include <map>
#include <string>
int main() {
std::map<int, std::string> units = {
{1, "one"},
{2, "two"},
{3, "three"},
{4, "four"},
{5, "five"},
{6, "six"},
{7, "seven"},
{8, "eight"},
{9, "nine"},
{10, "ten"},
{11, "eleven"},
{12, "twelve"},
{13, "thir"}
{14, "four"}
{15, "fif"}
{16, "six"}
{17, "seven"}
{18, "eigh"}
{19, "nine"}
{20, "twenty"},
{30, "thirty"},
{40, "forty"},
. . .
};
}
coal
then you can parse every digit in the number and combine values of the map to create a string
coal
for example, units[40] + " " + units[8] is "forty eight"
coal
you just need to engineer the way to know which ones to combine
coal
the first 19 values will be the hardest ones as english is quite inconsistent there
coal
but it becomes repetitive after twenty

Hello, what means "&&" after a type?
Like this std::string&& f_name
coal
Hello, what means "&&" after a type?
Like this std::string&& f_name
reference to reference (rvalue reference)
coal
usually used to perform perfect forwarding

thx

reference to reference (rvalue reference)
That is wrong.
&& is an rvalue reference which is not a reference to a reference.
C++ doesn't allow references to references because references are not objects but aliases.
References to references can inadvertently be created through template programming or through typedefs and using aliases, but the reference collapsing rules account for it and convert such cases to either a lvalue reference or an rvalue reference.
A rvalue reference is just a new type of reference introduced in C++11 that can be used to refer to rvalues (xvalues with a cast through std::move or std::forward or a prvalue).

usually used to perform perfect forwarding
This is also wrong. Rvalue references are not used for perfect forwarding. There is another kind of reference called a forward reference (or universal reference as coined by Scott Meyers'). These references are what are used for perfect forwarding. A reference of this kind is created when you have template function with T as a template parameter and the function has an argument of type T&&. Here T&& is not an rvalue reference but a forwarding reference.

Guys if you know some chanel on YouTube or a course in the internet that teaches you how to use C in web dev,
Please tell me thanks

ah i see, there's little information about these different kind of semantics for (almost) the same syntax so i misunderstood

Hello guys,does anyone know about the fuse framework in linux? About the functions in /usr/include/fuse/fuse.h, does anyone know how to implement them? I haven't found any documentation about those function parameters on the Internet, do I still need to know Any other knowledge?

struct kims Book1=["C Programming",2021,127]; -> struct kims Book1={"C Programming",2021,127};

structure initialization needs to use {} instead of []

Three variables next to each other in memory.
0040141e c7 44 24 MOV dword ptr [ESP + a],0x73736170
38 70 61
73 73
00401426 c7 44 24 MOV dword ptr [ESP + b],0x64726f77
3c 77 6f
72 64
0040142e c7 44 24 MOV dword ptr [ESP + c],0x333231
40 31 32
33 00
—————————————————————————-
undefined4 a;
undefined4 b;
undefined4 c;
Values in a,b,c with their ASCII char respectively:
a = 0x73736170; //"ssap"
b = 0x64726f77; //"drow"
c = 0x333231; //"321"
char pass [30]; // any string.
So, if I do,
strcmp((char *)&a,pass);
Will "a" take everything in the memory as a string until it reaches "\0" ?
0040142e c7 44 24 MOV dword ptr [ESP + c],0x333231
40 31 32
33 00
Since there's 00 after 33 in the memory at this address.
mito
english
\Device\NUL
c = 0x333231; //"321"
This already contains a NUL char.
0x333231 is equivalent to 0x00333231. As per the mov is dword, hence 4 bytes.
mov dword ptr [ESP + c],0x333231
is the same with:
mov dword ptr [ESP + c],0x00333231
As such, the bytes representation is "321\0".
\Device\NUL
Recall that x86 follows little endian byte order.

The problem starts after this line

You're declaring the array before length has a value. Input the length first, then declare
It helped. Thank you very much

@ankit1w but if I delete everything after this line it will work even if I don't change what you said
It's unpredictable behavior. On some system, it might run without any errors at all. In some system, might fail early on.
Compile with the -Wall flag to see warnings. Under optimal conditions, your code shouldn't have any warnings.

Can anyone suggest a good integration test framework for c++ project something like rspec but framework needs to be either c++ or python, guys how do you do your integration tests ?
Daniel
Hello guys, how are you? Can someone help me?
Daniel
It's very simple, I am sure. But I am very jr yet
Daniel
What’s your question?
so, i am trying change this comparison
if(memcmp(data, &chunk[i], len) == 0)
Daniel
to a comparison with float values.
this above work but only for string/char values
Daniel
i am scanning a process memory, trying find the value 0.12048
Daniel
but, memcmp does not work with float values, and data == $chunk[i] not as well
Daniel
the point: how make the comparison but with float value
Prometheus

Could try converting the float to a string
