i* my mistake 😅

from 2 to sqrt(i)

Use for loop for (int I=1; I<=4;I++){ Cout<<I<<endl; }

Goodmorning, is anyone here want T-shirts or like with a specific design, finally, is available, you can now buy a T-shirt, iphone cock, labtop skin..... with the design you want, if you re interrested contact me..

Yeahhh, so, follow what Madhu said. char[] is a list of actual characters so each EventE[N] will only get one character up to a nil character. Also note that you are declaring EventE twice - you need to remove the second declaration.

I learn dynamic memory allocation in programiz.com

About Malloc in c programming What is the correct statement to allocate a string of run-time variable size LEN? 1) char str = malloc(LEN); 2) char *str = malloc(LEN); 3) char *str = (char*)malloc(LEN); 4) char *str = (char*)malloc(LEN*sizeof(int)); 5) int *str = (int*)malloc(LEN*sizeof(int));

auto str = (char*)malloc(LEN);

Why not 5 ?

5 is not a string It's a pointer to ints(array pointer)

Ah, you're right. Sorry my bad

auto str = (char*)malloc(LEN);

That line alone raises some questions :) Like, if it's C then why auto (will it be int in C?) If it's C++ then why malloc :D

Does auto without asterisk will declared into pointer automatically or just normal variable ?

In C++ the type will be deduced to be a pointer (char*) in this case.

😂I only know it works

In g++😁

I am studying C++ And i joined the group to learn more about programming with c++

Hi guys! I am really confused about this line: uint32_t val = *(uint32_t*)&a; (a has another type, for example float) I still don’t understand in which standards it can be work fine, because in my compiler (gcc) it gives me the value of 0, but a is 1.5. Is it forbidden to cast pointers?

It's not forbidden but you should use it only when you want to work with bits. https://stackoverflow.com/questions/15578935/proper-way-of-casting-pointer-types

In C++ std::cout<<"*" In C #include <stdio.h> printf("*")

it was not an ad, was it, i pasted the telgram channel link which post job vacancies. Was that rule violation ? @admin ?

Won't it violate posting links, as well?

Help finding me unique number from an array of n numbers, n taken from user.. Eg Input 11 5 3 1 5 1 3 4 7 4 8 8 Output 7 (Because all elements except 7 aur occurring double)

Help me to Write a C program to implement the functionality of command “cat file1 file2 > file3” using fork() system call. Where the file names are the input to your program. Your program should check whether the given file names exist or not. If the file doesn’t exist, display the error message and exit the program.

Tell me where I am wrong #include<iostream>  using namespace std;  int findunique(int arr[],int n)  {   int i=0;   while(i<n)   {       bool found=false;       int j=1;       while(j<n)       {           if(i==j)           {               continue;           }           if(arr[i]==arr[j])                   {                       found=true;                       break;                   }                   j++;       }       if(!found)       {           return arr[i];       }       i++;   }  } int main()  {      int n;      cin>>n;      int arr[100];      for(int i=0;i<n;i++)      {          cin>>arr[i];      }      findunique(arr,n); }

Whatever you are comfortable with.

Anyone pls?

here you code : #include<bits/stdc++.h> using namespace std; int findunique(int arr[], int n); int main() { int n, b; cout << "what is the dimension of array: " << endl; cin >> n; int arr[100]; for (int i = 0; i < n; i++) { cout << "[" << i + 1 << "]th element" << endl; cin >> arr[i]; } b = findunique(arr, n); if (b < 0) { cout << "Number not found" << endl; } else { cout << "found :" << b << endl ; } return 0; } int findunique(int arr[], int n) { int i = 0; while (i < n) { bool found = false; int j = 0; while (j < n) { if (arr[i] == arr[j]) { found = true; return arr[i]; break; } j++; } if (!found) { return -1; } i++; } return -1; }

Guys exactly why cpp modules??

can getpid() return a negative value

Its a new feature of the cop compiler, allows to produce a binary file out of cpp and or header files, that can be used during compilation. It should speed up the compilation time… i don’t understand how it’s different of supplying header and binary for a library or module

C++ for AI or Python for AI 🤷‍♂

Modules were not added to speed up compilation time. That is a side effect. Their main advantage is that they get rid of problems with header files like independent compilation (modules are compiled independent of the source files that include them. This is very different from Precompiled header files which was a way to speed up compilation times for header files that are often included. This required the header files to be included in a specific order dependent on the implementation). Macros and preprocessor directives in a module are explicitly prevented from being exported which means they have no effect on the source code that imports the module. Also source code which is not exported from a module will not affect the source file that is importing the module which speeds up compilation. Also modules have the advantage of not impacting your code irrespective of the order in which they are imported. The rules for overloading are also simplified because the declarations in the source file do not affect the overload resolution process in the importing module. All of these work together in speeding up the compilation process because modules can be compiled independently into a binary format that is similar to an AST generated by a parser in the compilation process and this AST can be processed much faster by the compiler during compilation of a translation unit which imports the module.
