Why bother? Create an app that'll make you billions rather than making a new language which no one will use.

yeah
creating an app is just for making money
but creating something which can create apps
it's teach you many thing that only few people know

Check fgets return value first

The variable defined by &, means variable is reference
So what does this mean?
const int& x = 50;
We defined the reference variable with a number. What is this variable referring to now?a
50 is a temporary object and should be destroyed by ;
But! const& (const reference) extends a lifetime of the temporary object to a lifetime of the reference.
Is that clear or too hard to understand?
P. S. I don't recommend you using this feature as it can lead to errors and is not really good

Agree. One thing that it doesn't extend lifetime of member variables of the temporary object that goes out of scope, but some developers don't think about this and expect that const ref will still be valid in this case.

Because it is not able to open the file

I think that the user who runs your program isn't in the authorized group to access the file

Wtf? Why do you sort in a loop?
so that I don't have to worry about the houses to select of low rates.. and they will be added to the counter....

In C language
Consider the following data structure, representing a binary search tree ordered on the node_id field.
struct node{
int note_id;
char node_content[30];
struct node * right, * left;
};
Write the recursive function to print the content of the node with the smallest id of the tree.

Your problem description does not say anything about range of the N. If N can be reletivetly large (millions) you program would not work

yeah I have to have to use ll for that, and I also have to use vector...

You need to understand declaring/initializing of variables within {} scope.. of your program.
Try each case..1by1..
—
#include <iostream>
int main()
{
//int x=0; //Case:1
for(int i=0; i<3; i++) {
//int x=0; //Case:2
for(int j=0; j<3; j++) {
int x=0; //Case:3
std::cout <<"\n" <<&x <<":" <<x;
x++;
}
}
return 0;
}

But sometimes too many loops causes trouble in understanding the code
Pavel
If it's used as break for inner loop, then putting the loop to a function can help (well, arguably sometimes goto reads better)

Loops showing the execution flow, goto doesn't show anything.
When you read the code with goto, you need to pay more attention to understand the flow correctly and not miss something.
