Can you make it more easy and understandable?

Are u being sarcastic here 👄
No no I not understand that question properly , that's why I'm telling

Thank you to explaining to me🙏now I try☺

*The tuition fee for Data link institute is $2000 per year. Suppose the university financial committee recommends that tuition should be increased at an annual rate of 5%. Write a program that uses a loop to compute the tuition in ten years.*
Please can someone help me with this
//A proposed solution
#include <stdio.h>
int main() {
int year,fee=2000;
printf ("Year 1: 2000$\n");
for (year=2;year <=10;year ++)
{
fee+=fee*0.05;
printf ("Year %d: %d$\n",year,fee);
}
return 0;
}

strlen(arr2) on assigner is O(n), you could just insert logic to find NULL character and place it into the loop, or place strlen(arr2) into another temp variable so it wouldn't be O(n).
Don’t actually get what O(n) is
Googled on how it’d help but couldn’t understand a thing
Also I’ve tried breaking the loop once arr2 == ‘\0’
Still not working

O(n) is big O notation https://en.m.wikipedia.org/wiki/Big_O_notation

I’m trying to sort a string of names in ascending order with this code but I’m having an error (The names are sorted alright but there are some garbage alphabets added to some of the names)
It works fine when i use the swap() function to swap the names but only gives me the error when i use the for loop
Been trying to figure the error out for a long time so someone please help me if you can🙂
Declare size_t i outside the for loop and add a temp[i] = '\0' before ending the assigned function

What he means is that you have to loop through the whole string to get the length, and then loop through it again to set the characters for temp.
If your for loop was something like this :
for (size_t i = 0; arr2[i] != '\0'; i++)
You're essentially doing the same thing but taking less time.

Did you understand why?
Yes i understand how that worked.
I’m trying to understand how O(n) is related to the first error i was getting

It's not related, it was just a suggestion, and a great one

This what I did using Java
package simpleinterest;
import java.util.*;
 
public class SimpleInterest {
 
 
   public static void main(String[] args) {
       //Declare and Initialize the Principle, Rate and Time Period
       float P = 2000, R = 5,
       for(float T = 1; T<=10; T++){
           System.out.println("The entered principle amount is = " + P);
           System.out.println("The entered rate is = " + R);
           System.out.println("The entered time period is " + T);
           
            // Calculate simple interest
       float SI = (P * T * R) / 100;
       //Print the simple interest
       }
       System.out.println("total is  = " + SI);
   }
   
}

And unless for some reason you need to code it like this, I'd just use an array of characters pointers instead of a 2D array and swap the memory addresses instead of the actual contents inside memory.

The indicative breakdown of marks for each part of the assignment is as follows:
ipc_jobqueue.c - 10 marks
job.c - 15 marks
joblog.c - 15 marks
jobqueue.c - 20 marks
mutex_peterson.c - 10 marks
sem_ipc_jobqueue.c - 20 marks
shobject_name.c - 10 marks
For full marks your solution must:
Pass tests for the above files (some of which may be more comprehensive than the tests provided with the project), and
Comply with instructions given in this specification and related material (including in relevant .h files, .c files and README files), and
Demonstrate good programming practice particularly with respect to non-functional aspects. Good practice includes (but is not restricted to):
Not overcomplicating solutions
Guarding against memory leaks
Safe use and choice of system and C library functions
Where appropriate, programming defensively with respect to input parameters to functions and return values of functions you use. "Where appropriate" means that there is a trade-off between programming defensively and not over-complicating your solutions. However, you should guard against propagation of errors to the underlying system. The specification of functions will give some indication of what is expected in terms of managing erroneous input.

Hello guys, can someone tell me what i need learn tô understand this code?
Daniel
( ( void (*)( ) ) ValidateFns[0] )( );
Daniel
I know pointers and arrays
Daniel
But this is very confuse
coal
function pointers
Daniel
Will It call the function?
Daniel
Great! Thank you man!
Alviro Iskandar
But this is very confuse
Pay attention to the part that's marked by ^^^ below.
( ( void (*)( ) ) ValidateFns[0] )( );
^^^^^^^^^^^^^^^
This part is a cast to a function pointer that has unspecified number of arguments and returns void (or doesn't return any value).
( ( void (*)( ) ) ValidateFns[0] )( );
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This whole part results in a function pointer, and the () after that means invoke the function, so you call that function.
For example:
void test()
{
printf("test");
}
int main(void)
{
void *arr[10];
// fill this with the address of a function
arr[0] = &test;
// cast to a function pointer and call it
((void (*)())arr[0])();
return 0;
}
The above code effectively calls test(). It's simply like:
void test()
{
printf("test");
}
int main(void)
{
test();
return 0;
}

Awesome!! But, I am thinking... when this could be useful? I can't se why do a pointer if we have access to source code.
coal
coal
for example, curl library needs you to specify a function pointer as the write_callback method of a response
coal
so it calls your custom function
coal
it's the C closest resemblance of C++ lambdas
coal
but not the same thing, as lambdas dont necessarily have names
Daniel
Nice tips! I will read more about this with those new knowledge
Daniel
Before I forget... sorry for my bad english! I am begin in C language and in english language too!
coal

also, i recommend you to translate all sentences you write, to practice english
you write a sentence and check how the proper version looks like

Can someone plz explain to me how shell sorting work ?some notes or examples ...I tried it online but it's going over my head. Thanks in advance
Krishnaa
Anyone attempted last night's LeetCode's Weekly contest???? If not so, can u guys please look at the "Append K Integers With Minimal Sum".
Krishnaa
class Solution {
public:
long long minimalKSum(vector<int>& nums, int k) {
sort(nums.begin(), nums.end());
long int i=1; long long sum=0;
for(int j=0; j<nums.size(); j++){
if(k==0) break;
else if(i<nums[j]){
sum+=i; i++; k--; j--;
}
else if(i==nums[j]){
i++;
}
}
while(k--){
sum+=i; i++;
}
return sum;
}
};
Krishnaa
Please optimize the above code. It passed 77/107 test cases. and shows TLE.

How do you organize your CMake project?
I'll make my question more clear.
I have a build/ dir from conan and a src/ dir where the sources of the main executable are located.
I plan to have some sub projects, but this way I'll have to write all the dependent *.c files in the cmake file.
I'm not very fluent about cmake; is this the correct way?

There are ways to recursively add c/cpp files to cmake that I use to create libraries (I know it's not really by cmake design, but at least it works with one cmake file).
Example I have here, note add_folder_as_library:

Oh I see, you're glob-ing the files directly

and adding them as static libraries for each folder

int result = strlen(aaa);

I entered Hello , it returns 6 instead of 5. I know it's because of fgets. Then I entered 12345678 and it returns 7 instead of 8

I can't send you an example because this group doesn't allow to send images
if you want I can send you how my setup looks like

I entered Hello , it returns 6 instead of 5. I know it's because of fgets. Then I entered 12345678 and it returns 7 instead of 8
So it returned 6 because fgets always puts \n at the end of a string. But why it returned 7 after second execution? I wrote char aaa[8] and entered 8 characters. What does fgets do in this case?

Hey anyone in the first program when I use scanf to take 2 values at once result is not coming properly, why is it so in second when I take scanf separately I am getting correct answer. Help out
