again, you need multiple indices, a_i and b_i and c_i e.g.
size_t a_i = 0;
size_t b_i = 0;
size_t c_i = 0;
while (a_i < a_s && b_i < b_s) {
// ....
}

OK.. I'll try this, ty alot as usual!

what is this code about ?🤨
merging two sorted arrays (obv doesn't work, just the idea how to get started)

so you sorted them successfully?

It's not my assignment, just wanted to provide part of the basic skeleton for someone else

after the loop, lst will be NULL
} else {
while(lst != nullptr){
lst = lst->getLink();
}
lst->setLink(newnode);

I even corrected this, and in fact manually traced the segmentation error, the method isn't even being called in the second iteration

From the information given, GDB suggests otherwise
Program received signal SIGSEGV, Segmentation fault.
in Node::setLink (this=0x0, p=@0x7ffffff1d8: 0x7fbdc2c020)
^^^^^^^^
at codebeautify.cpp:316
316 void Node::setLink(const NodePtr& p) { link = p; }
^^^^^^^
(gdb)
In all the code you shared, there is only one call to setLink. Now, surely the faulty call can happen anywhere (e.g. swap), but since we neither have the full code nor the stacktrace it's up to you to figure that one out
While tail_insert was calling setLink on NULL, I don't see any more places - so, can't repro
Please follow #mcve

I just redid the whole thing in the same way, same algorithm I used before and it magically works

I want to change this code with functions but i don’t know how , can you explain me if you know ?
Can you be more specific?
Raru
Change this code with functions pointers and dynamic memory allocation

"how" is to generic, focus on steps you have to take in order to solve it

Can anybody explain how you create a linked list with n node?
Anonymous
It's a simple concept but I am having trouble implementing it
Alex
what do you mean with n node?
Alex
do you need regular linked list with size n?

enter the no of elements in array:3
enter the elements:
enter element at 0:1
2
enter element at 1:3
enter element at 2:4
the unsorted list is :1 2 3
the sorted array is :1 2 3

You can change you format string to ignore leading whitespace characters by replacing "%d " with " %d"
for (int i = 0; i < s; i++)
{
printf("\nenter element at %d:", i);
scanf("%d ", &arr[i]);

got it. i never thought there was a difference.
why shouldn't there be any difference? " a" is not the same as "a "

i thought it is just white space before and after.how could it affect my loop.
olli

You could "peek" at stdin (getchar + ungetc) to see which character will be read next. Your loop tries to read (char)10 (*) which is not a digit and hence the format string does not match
(*) assuming you're entering the values on a local cmd, depending on the exact interaction the result might differ

Using decision making statement(s), Write a simple program that can be used by security personel to check if a person being scanned at the gate is a positive suspect for corona virus, the program should record person's names department and body temperature, the test condition for your program is: if the temperatures recorded is above 38, The program should alert the personel that the student is suspected to be sick and procedure is to be isolated, if not he should be let in freely with a ‘normal temperature’ alert.

How do I round up numbers to multiplies of 16?

How do I round up numbers to multiplies of 16?
Try this one:
#include <stdio.h>
#include <stdint.h>
int main() {
uint32_t i = 20;
uint32_t tmp = i & -16;
while (tmp < i) {
tmp += 16;
}
i = tmp;
printf("%d", i);
}

sounds slow 🤔

inline static uint64_t size_align(uint64_t num) {
return ((num + sizeof(struct memchunk_free) - 1) / sizeof(struct memchunk_free)) * sizeof(struct memchunk_free);
}
This did the trick for now
