in Linux there should be built-in compiler g++. Mingw is for windows and not needed to be installed in Linux, I think

Windows crushed and I cannot get to repair with recovery but I can access the files when I boot with Linux...so now am asking if there is a way to extract the softwares that were in windows partition as I can with the other files
Unfortunately I have no idea 😂💔 which Linux distro are you using?

Hello, I have a doubt
Actually for c++ ,
I am unable to setup VScode in Linux.
I have downloaded VScode but for coding....I am unable to understand that how I can setup minGW in Linux
In Linux there's a pre installed c compiler (gcc) so after installing VS Code and the C/C++ extension, you write your c code, save it then go to the terminal and type
gcc -g [appname.c]
You will see an output file (a out)
If you want a custom name for your output file, you compile as follows
gcc -g [appname.c] -o [customname]
If it compiles with no errors, you type
./a.out
Or, if you provided a custom output file name type
./[customname]
If these steps don't work, feel free to let me know

If most of the programs reside in program files or Programs Files x86, You can copy those with cp or using a file manager. If it is an older version of Windows(I don't know about newer ones), Copy Appdata from your Users folder.

I don't know about VSCode but it is easier via terminal. You can use g++ or my favorite compiler clang++. Just cd into the folder. ie, If my program is in Documents folder, I will do
cd ~/Documents
g++ my_program.cc -o my_program.o
And run the program using ./my_program.o
//If you use clang, you can replace g++ with clang++
//Also, learning about make files will give you better advantage

Or gcc
I wouldnt use gcc since g++ is better for c++ programs provided I don't have to use any specific flags

I wouldnt use gcc since g++ is better for c++ programs provided I don't have to use any specific flags
Basically g++ is gcc -lstdc++

On a course offered by IBM ar EdX, a definition of an operator (+, for example) says that the first argument is implicit (accessed through this->) but Bjarne, on his “The C++ Programming Language 4th edition”, explicit work with 2 arguments.
Then I ask: what form works?
T operator +(T arg2) {…}
or
T operator +(T arg1, T arg2)
?

am stuck at merge sort, can someone please message me? i need some real help
Merge sort is partially already a part of the standard library as std::merge merges 2 sorted spans into another (for a copying merge sort). You should look at what it does and think about how you could use that to sort an array, past that and a little thinking and you should be more ready to implement it
Miki
An array is said to be vector array following this conditions :-
1)it contains atleast one odd value.
2)the maximum value of an array is must be even number.
3)every value of odds in the array must be greater than every value of even numbers exept the maximum even number
Please help me to write this code in c++ 🤲🤲🙏🙏

Hi!
So, I'm practicing pointers and LinkedList in C.
I have this function "add", for adding a new node to the LinkedList.
I initialize the linked list struct as null:
Node *list = NULL
Then I pass this Node to the add function which has the following definition:
void add(Node *n, int value);
First I create the struct representing the first node, called p.
Node *p = malloc(sizeof(Node));
p->value = value;
p->next = NULL;
So far, so good.
The second thing is checking whether the received pointer is null or not, so as to define it as the first item on the list.
if (n == NULL) {
n = p;
return;
}
This is where I don't get it. The address of p is set to n, but just within the scope of the function add. When I get back to main, the address of *list is still NULL. I'm not passing it by value, but by reference, but it's clearly not working and I'd like to understand why.
Ty.
I'll try to send the whole code on a link.

I think the problem in your code is that you try to implement the list inside a node struct, the better way is to split this into two structs: Node and List. Node is a pair of pointer and value, List is a pointer to the first Node or nllptr. You add function than gets passed a List* instead of Node* and your current problem should be solved
Guljar
#include<stdio.h>
#include<conio.h>
main()
{
void add(int x, int y);
void sub(int x, int y);
void mul(int x, int y);
void div(int x, int y);
int a,b;
printf("enter a first number");
scanf("%d",&a);
printf("enter a second number");
scanf("%d",&b);
add (a,b);
sub(a,b);
mul(a,b);
div(a,b);
getch();
}
void add(int x,int y)
{
int c;
c=x+y;
printf("%d two number is add",c);
}
void sub(int x, int y)
{
int d;
d=x-y;
printf("%d two number is sub",d);
}
void mul(int x, int y)
{
int e;
e=x*y;
printf("%d two number is mul",e);
}
void div(int x, int y)
{
int f,e;
f=x/y;
e=x%y;
printf("%d is the quetent",f);
printf("%d id the remender",e);
}

The list implementation actually works.
The struct has a pointer to the next struct. I'm not understanding why I'm attributing the pointer p to the pointer n, but when I get off the scope of the "add" function the *list pointer doesn't have the value of p.
*list is the struct initialized as null and used as the argument to the add function.

I dont think it actually works, try to look at your <lista> variable in main with a debugger, you initialize it as a nullpointer which you then pass on to your add function. Add then tries to write the new Node <p> into an invalid memory location. You need something like this: struct List{Node* head} , then you can assign <p> to List.head

I expressed myself poorly.
This implementation, with the list initialized as null doesn't work the way I liked.
Before this, I was initializing the list with some random value and then passing it to the add function. It worked this way, but I didn't want to implement it like that, having to initalize the list manually and then passing it. I wanted the 'add' function to identify "oh, the list is empty, so this item will be the first" and assigned the first value to the list initialized as null.

Yeah this makes sense, if you initialize it with some random value, lista is not a nullpointer and the rest should work just fine (but this approach also wouldnt work for doubly linked lists)

Piece of advice from a beginner like myself
1. Get your hands dirty
2. Repeat 1 over and over again
Go to YouTube
Type something like “Learn c++”
I believe it’ll be a good way to start
