yeah.
(mpesabalance >= 200 && mpesabalance < 500)
You should not add a semicolon after the if and else if condition.

If the intention is to use a bloomfilter, then shouldn't you be using the password list itself instead of the password hash list?
You can directly use the hashes without needing to rehash them and sha1 is pretty standard

No my point is that storing in a bloomfilter would be more efficient if you hash the original password with "multiple hash algorithms" rather than hashing a hash value. Sha1 hashes all have a fixed length and hashing them may lead to pretty frequent collisions (this will lead to more false positives). Passwords on the other hand are varied length.

hi, guys. i use std::bitset<> in my project. and i want to the std::bitset<> to a binary string write to a file. but seems the std::bitset<> don't provide similar function to me? can someone know how to solve it?

In stack context there is a Top element .Which you can access. Last pushed element is on top. (LIFO). First element - 14 - will be accessed last.

I have a code that collects data from cells, when you try to turn it in the opposite direction, a division by 0 flies out, although it is not close there
value = kop * power((14 + 6 + 7)) + mod1 * power((6 + 7)) + reg1 * power(7) + dst;
|
\|/
dst = value % power(5);
reg1 = value % power((5 + 7)) / power(5);
mod1 = value % power((6 + 7 + 5)) / power((7 + 5));
kop = value % power((14 + 6 + 7 + 5)) / power((6 + 7 + 5));
Types of data
unsigned long value, value_a, temp;
unsigned char kop, reg1, dst, kop_a, reg1_a, dst_a;
unsigned short mod1, mod1_a;
UPD: power(x) is 2^x

You don't need to hash the hash value tho, you can just use it split into several bit samples

mostly msvc, gcc, clang and rarely ICC. Depending on your platform MSVC or GCC might be the easiest to setup and use.

Yes, it seems that is written exactly in the docs "This extension is not implemented in GNU C++. "

guys, when doing recursion, if you're not careful, you get a segfault
but when using execve, no segfault occurs, it just goes on forever. why?😃

I mostly use Clang, but I also use GCC, Msvc and NVCC. I teach to people using Msvc and trigger infinite amounts of anger when I show them comparison of error messages between compilers (Msvc is bad at error reporting in C++)

hi, i am currently learning c language. I am doing a program to determine the prime factor of given number. Mine work well for single number, however the project requirement is that, i have to find the prime factor of a given range number.
for example
given a=4 , b=10
prime factor for 4= 2*2
prime factor for 5=5
prime factor for 6=2*3
.
.
.
prime factor for 10=2*5
it will be nice if any of you can help me understand, how do i build the program.

if you have function that determines this for f(x) then you can just run it for x in range of 4 to 10 no?

im not sure cause im really new to this,i just started a month ago, im not sure how to define the f(x) as well

you said you already have that program that works for single number no?

i do it this way, there will be 2 numbers entered, for a and b, however for the loop, only work for a
For example: a=8, b=10
the output would be
2*2*2*
nothing happpen to b, and also not for the number between 8 to 10

printf("%lu*",i);
a/=i;
}
else
i++;
}
return 0;

well you are taking your input from the user... but you can split this program into more function, create one function that is
void print_factors(unsigned long int x)
which will get that a from main and do the same as this program, then you can extend it to cover a range

I want to create a array of int type but it's size in unknown(depends upon user input), then how to declare that array because writing int arr[]; was throwing error of storage size of ‘arr’ isn’t known

you need use vector

you need use vector
is this a datatype?
isn't there any other way, I just want to input an array.

its best practice to write , "using namespace std ;" within the function definition. start doing it from now
dont use it as a global variable

I think it have some issue
It should be
