https://paste.ofcode.org/vMf44PT6TcbQapDejju6J4 I need help about a c recursive problem, the problem's leetcode link and the necessary algorithm explanation link were written in code as comment lines. Could you please help?

I'm getting correct results besides wrong results

kinda off-topic, but I'm curious about how Java's new keyword works compared to C++'s in C++ we handle memory management, so new keyword just means to allocate at heap. we can instantiate objects allocating at the stack or the heap. but in Java, which has a garbage collector, new keyword seems to mean "give me an instance, wherever you want to allocate". the garbage collector decides where to allocate based on some criteria or always allocate at heap?

always allocated on the heap

If you need something more precise, do active sleep, just an empty loop with elapsed time checking

if you need something more precise, you need realtime os

pls someone can help me? I am making a program that tells me the higher number among the numbers entered by the user. The quantity of numbers is up to the user sry I traduce all #include <iostream> using namespace std; int computation (int max [], int n) { int i; int maximum = max [0]; for (i = 1; i <n; i ++) if (max [i]> maximum) maximum = max [i]; maximum return; } int main () { int quantity; int number; int i; int max [] = {number}; cout << "how many numbers do you want to insert?"; cin >> quantity; for (i = 1, i <= quant, i ++); cout << "insert the numbers, always returning between one and the other"; cin >> number; cout << "Largest in given array is"; << calculation (max); return 0; }

Variable length array isn't in Standard C++

AUTOSAR seems to be a specification like opengl but for smart cars

what is the problem in this code it works but it doesn't give a right answer

\Device\NUL

delete & on the printf

\Device\NUL

#include <stdio.h> int factorial(int n); void main (void) { int number; int z ; printf("enter a number of factorial to get it "); scanf("%d",&number); z=factorial(number); printf("factorial %d = $d \n",&number,z); } int factorial(int n) { if(n==0) return 1; else return(n*factorial(n-1)); }

Your formatting is wrong tho

Hussein

#include <stdio.h> int factorial(int n); void main (void) { int number; int z ; printf("enter a number of factorial to get it "); scanf("%d",&number); z=factorial(number); printf("factorial %d = $d \n",&number,z); } int factorial(int n) { if(n==0) return 1; else return(n*factorial(n-1)); }

remove & when you print the number

Hussein

#include <stdio.h> int factorial(int n); void main (void) { int number; int z ; printf("enter a number of factorial to get it "); scanf("%d",&number); z=factorial(number); printf("factorial %d = $d \n",&number,z); } int factorial(int n) { if(n==0) return 1; else return(n*factorial(n-1)); }

the line that prints the results should be like the following printf("factorial %d = %d \n",number,z); with & you were printing the address (position in memory) of variable not the actual value of it

Hussein

the line that prints the results should be like the following printf("factorial %d = %d \n",number,z); with & you were printing the address (position in memory) of variable not the actual value of it

which means that the weird huge number was the position of the of number not the actual number also $d is incorrect you should use %d instead

#include <stdio.h> unsigned int factorial( unsigned int n); int main () { int number = 5; int z =factorial( number ); printf("factorial of %d = %d \n",number,z); } unsigned int factorial( unsigned int n) { if(n==0) return 1; return n * factorial(n-1) ; }

did you only add unsigned ?

I wanted to enter the number from the screen

Hussein

I wanted to enter the number from the screen

you can do that with scanf( “” , &number ) and declare it as int number;

Hussein

did you only add unsigned ?

and removed the else statement it wasn’t necessary

Hussein

I wanted to enter the number from the screen

I used a online compiler so I couldn’t use it

Hussein

I wanted to enter the number from the screen

for printing you shoild do this 👇 printf("factorial of %d = %u \n", number , z );

Hussein

for printing you shoild do this 👇 printf("factorial of %d = %u \n", number , z );

sorry I forgot to fix it when I changed it to unsigned

Nothing, it just returning without printf anythiing

Hi everyone, recently I first met #pragma push_macro and #pragma pop_macro I can't find detailed information about them. I understand that they can save some definition of macro into its stack and then restore it. But how it affects on compatibility Microsoft with GNU compilers and where I should use it?
