virtual ~ParticleSpecies() = default;
I did this, it got rid of the warning message but I have no idea if it solves the issue the compiler is trying to warn me about.
Just followed this.
The reason why you need a virtual destructor is because if you destroy a Derived class object using a Base class pointer (by using delete expression) it will result in Undefined Behavior.
Now using =default for the virtual destructor depends on your class. If you have nothing special to do in the destructor then the default destructor provided by the compiler should suffice

replace (t—) by stating True or any Integer will give You the output

I want to save *x and *y value to player so that I can use work with them

well you need some datastructure to hold both of them then, like a struct with 2 chars pointers

Hi, i have non related to C programming question.
(-9)*(-11)
Convert these 2 decimal numbers into binary and multipy. When i try to solve this. Always getting wrong answer. Any body can help me to solve this?
Дон
Dinuka
How looks your converting function?
Seems like i do it wrong. 1st i convert to binary and get two's complement. But both negative numbers, so i do not need to get two's complement right?
Дон

Iirc you can compute the result of multiplication and then convert it into binary. Sample:
(-9)*(-11) = 99 --> convert 99 into binary

Your append function logic is wrong, you should reach to end and then you should add the next node as newNode.
append function:
While(ptr->next)
ptr = ptr->next;
While ends
Ptr->next = newNode
Captain
Also for display function you should check if ptr becomes null in while condition which will print all elements

#include <iostream>
int main(){

int size = sizeof(ages)/sizeof(int);
float total = size * 10 ;

if ( min < ages[j+1]){

}
else {

}
}
std::cout << min;
-----end------
In the above code I want to print the value of _min_ variable which is in for loop but I cannot as it is out of scope and if I declare the variable outside ,it prints the value which is not affected by for loop

And check this line:

Ohkay , I fixed that but still how I print the modified value of min from second loop

define your min variable before for-loop (int min = ages[0];) and you don't need the else branche/total variable/size variable.
also your if-brance not correct, do:
if (min > ages[j]) min = ages[j];

nooby question about C
suppose i have this struct:
typedef struct A {
uint8_t some_array[6];
uint8_t some_int;
} A;
and suppose i have a pointer to it, say A_ptr
when accessing some_array through the -> operator (A_ptr->some_array), do i get the pointer to the array?
and when accessing some_int the same way, is it the pointer to the int or the value itself?
artemetra 🇺🇦
i guess the array decays into a pointer but i'm not that familiar with that (i mostly used C++ before)
pavel
The same as in c++
pavel
Some array - pointer, some int - value

I'm not a C programmer, just decided to test it. It seems like you get pointer as soon as you assign it to something (note the warning), but just the result of that expression seem to be an array (note the sizeof) https://wandbox.org/permlink/gDyEuJjL5y2NTmsN
