Nikita

i need to do that with C

Anonymous

ok

Nikita

i need simply write a function which returns some element?

Sourabh

what's "in unsorted order"

leave it intact dont sort it either in ascending or in descending order.

R

/hello

R

/hello

R

Nikita

leave it intact dont sort it either in ascending or in descending order.

thnx but i still can't imagine what i should to do

R

Smoke some weed

Do you have to implement the hash table as well

hellloooo

what is segfault ?

🤨

Mat

The language?

Francisco

But what, a compiler?

Mihail

You can't install c++. C++ is just a language

Mihail

You probably want a compiler

Mihail

I'd recommend Termux with clang or gcc

Aadarshhh

#include <stdio.h> #include <stdlib.h> #include <string.h> int* reverseArray(int a_count, int* a, int* result_count) { *result_count = a_count; int temp; for(int i = 0; i < a_count; i++) { temp = *(a + i); *(a+i) = *(a + a_count -i); //last elemnt is transfered to first *(a+ a_count -i) = temp; //first location is stored by last value } return a; } int main() { int arr_count =4; int* arr = malloc(arr_count * sizeof(int)); for (int i = 0; i < arr_count; i++) { scanf("%d", & *(arr + i)); } int res_count; int* res = reverseArray(arr_count, arr, &res_count); for (int i = 0; i < res_count; i++) { printf("%d", *(res + i)); if (i != res_count - 1) { printf(" "); } } printf("\n"); return 0; }

Aadarshhh

guys check my program it doesn't reverse the array

Aadarshhh

where I'm missing the point ?

Aadarshhh

In C , without using libraries

olli

#include <stdio.h> #include <stdlib.h> #include <string.h> int* reverseArray(int a_count, int* a, int* result_count) { *result_count = a_count; int temp; for(int i = 0; i < a_count; i++) { temp = *(a + i); *(a+i) = *(a + a_count -i); //last elemnt is transfered to first *(a+ a_count -i) = temp; //first location is stored by last value } return a; } int main() { int arr_count =4; int* arr = malloc(arr_count * sizeof(int)); for (int i = 0; i < arr_count; i++) { scanf("%d", & *(arr + i)); } int res_count; int* res = reverseArray(arr_count, arr, &res_count); for (int i = 0; i < res_count; i++) { printf("%d", *(res + i)); if (i != res_count - 1) { printf(" "); } } printf("\n"); return 0; }

Your for loop should stop after the half, you basically reverse it twice And as other mentioned, you need to subtract one from the a_count

Aadarshhh

still doesn't works

done but

Can you post the updated code?

Aadarshhh

#include <stdio.h> #include <stdlib.h> #include <string.h> int* reverseArray(int a_count, int* a, int* result_count) { *result_count = a_count; int temp; for(int i = 1; i < a_count; i++) { temp = *(a + i); *(a+i) = *(a + a_count -i); //last elemnt is transfered to first *(a+ a_count - i) = temp; //first location is stored by last value } return a; } int main() { int arr_count =4; int* arr = malloc(arr_count * sizeof(int)); for (int i = 0; i < arr_count-1; i++) { scanf("%d", arr + i); } int res_count; int* res = reverseArray(arr_count, arr, &res_count); for (int i = 0; i < res_count; i++) { printf("%d", *(res + i)); if (i != res_count - 1) { printf(" "); } } printf("\n"); return 0; }

In a pastebin please

In reversearray - your loop doesn't end after processing half the array (since you process two elements per iteration this is enough) - You should start with the first element i = 0 - the "upper" limit should be a + a_count - 1 - i

olli

He said in C though

Aadarshhh

thank you so much :)

Aadarshhh

pointer is taking my mind. :(

Aadarshhh

I think I have to shift to STL for problem solving.. It's quite easier to use libraries tehere.

Sourabh

Cpp means is it a type of compiler right

CPP means C Plus Plus, it is a programming language... 😕

Hello

Sourabh

What is the use of having so many programming languages why cannot be a universal language which can cater all the needs like we have english language as an international language? (Need your thoughts on it, thank you!)

Aquib

Because there is no one size fits all

Aquib

You can create performant languages which are close to the machine

Aquib

Very similar to assembly

Aquib

But very tough to write

Aquib

Or you can write code very similar to human language
