when I am doing the output tracing I can't explain how 20 came. I calculate but the calculation result is different can you please explain me the code?

Maybe a couple of simple logs are enough for tracing what happened there.

Sorry, It's hard to produce the correct code indent when I type in my phone, but what the code you post does?

oh i got the difference but the thing is i need to do output tracing I mean need to explain the code its my ans of the output tracing qus which is given to me.

Can you please explain how 14 came twice on the output. I am confused about
it.
Since, when i=4, j=1, K=4, x=10+4=14 ( Totally clear )
But, when i=4, j=2, k=5, x= ?
both of the condition is false here so what will be
the output here? and how?

an if condition without curly braces implicitly means its body just consists of one statement, and therefore in your code, the statement print("℅d\n", x); will always be called....

Get a good book and start getting familiar with the language.. but I guess you also need dsp knowledge to build audio applications

What is the usage of "Break" statement here and how 6 came on the output?
#include <stdio.h>
main() {
int i, j, x = 0;
for (i = 0; i < 5; ++i)
for (j = 0; j < i; ++j) {
x += (i + j - 1);
printf("%d\n", x);
break;
}
printf("\nx = %d\n", x);
}
Output on compiler: 0
1

6
x = 6
Press any key to continue . . .

how can I create a procedure that delete a student including his informations from a table?
for example I have a table which contains 3 students
1) student 1
2) student 2
3) student 3
I ask the user to enter the number of the student that he wants to remove from the table
he enters 2
what should I write as a code to remove student 2
are there any specific functions or methods?
thank you

class Student { ... };
std::map <int, Student> students;

Does anyone know what exactly is this?
std::iterator_traits<decltype(someVar)>::difference_type
Interested in difference_type, if I'm not wrong is this same as,
std::experimental::ranges::difference_type
?

That itself is a type, i want to know what it is
Anonymous
That itself is a type, i want to know what it is
Those types satisfy the same requirement of template <typename T> difference_type which is either the type T::difference_type is well defined or the expression`[](const T& a, const T&b){ a - b; } is well formed. So If `template <typename T> different_type` 's template argument T is same then they are same.

int A[2][3];
//filling the array ...
int x = &A[1];
The same code gives error in Dev-c++ but runs on code::blocks and gives the address of the first element of the second row.
The code has 2 logical errors which are :
1) storing address inside of an integer
2) storing address of an array(not just int) in a single int variable
I need to know why that happened and which one is right and which one is wrong

You can only change address on pointer
But how did it work on code::blocks
I though it will convert it to pointer automatically then store it but it didn't
X was still 4 bytes ( in my pc pointers are 8bytes)
And the address stored in x was right at then end
\Device\NUL
\Device\NUL
You do it by yourself
\Device\NUL
Size of pointer and its type is different
\Device\NUL
Even though your compiler is giving warning, it's bad
Karam
I know it is bad (my professor's example) but do you know how did it work on code::blocks , i mean an integer can just store 4 bytes but it stored 8
\Device\NUL
\Device\NUL
Btw, how did you know int pointer can hold 8 byte data while int can't ? int pointer is pointing so it's not related to its size. Pointer is used to keep address, not keep value
\Device\NUL
int data type on 64 bit arch is 32 bit. You will have integer overflow if you give it value more than it can holds.
