Tianwen 1 arrived near Mars in February 2021 to carry out Mars capture. In May 2021, the landing vehicle and orbiter separated, soft landing on the surface of Mars, The rover left the landing platform to carry out patrol and exploration work on the surface of Mars, soil properties, material composition, water ice, atmosphere, ionosphere, magnetic field and other scientific exploration, realizing China's technological leap in the field of deep space exploration. Deep space exploration will promote the all-round development of space science, space technology and space applications and make greater contributions to serving the overall interests of national development and enhancing human welfare. Before this, China has launched several man-made satellites into space, and there are n (1 < = n < = 5) man-made satellites, Each satellite has three attributes: manufacturing year, satellite number, satellite load (all attributes are integer values of int type), The number of satellites whose output load is less than the average load of n satellites is now required (the mean load can be divided by integer instead of using floating point numbers). Note: No legality check is required for input data, assuming all inputs are in compliance. Follow the following function prototype to write the program. struct sate {     int year;     int id;     int load; }; / / Define struct sate, which includes year of manufacture, satellite id, satellite load. int input (struct sate Sate[], int n); / / Enter the number of satellites n separately from the keyboard, and the different properties of each satellite. The return value is the number n of satellites. int solve (struct sate Sate[], int n); / / Based on input satellite attributes, returns the number of satellites with lower than average payload ans. Input format: the first behavior number n, line 2 ~ n + 1 are input three numbers, respectively for the first ~ n satellite manufacturing year, satellite number id, satellite load. Input format: Output includes only one line for number of satellites ans. Run example: 3 1984 334 40000 2012 531 20000 2021 341 60000 1

I need help for C

Can anyone give me the sample question of C++ and example code accordantly the question?

Guys/Gals a doubt, I have a class like class MEM { private: std::array<std::uint8_t, MAX_MEM> memData; // MAX_MEM is a const unsigned short public: MEM(); }; so the question is, how do I initialize the memData from the constructor (like memData[i] = 0 and 0 <= i < MAX_MEM), actually I plan to use constructor whenever I want to reset values of the object so basically I'll be doing something like MEM mem; mem.Reset(); // this will call constructor and reset all values if there's any other better way to do so, something like using copy constructor to assign a newly constructed object to already existing object and then destroying new one. So please do tell

just use your reset and do std::fill(std::begin(memData), std::end(memData), 0); but you could just use std::array directly or write an alias with your custom MAX_MEM

so no need to call constructor in my reset function, right?

right

of course you can also call fill in your constructor

yep doing this, thanks for the idea

also // MAX_MEM is a const unsigned doesn't work. it needs to be a compile time constant. use constexpr, #define (less preferable), or a template template <std::size_t MAX_MEM> class MEM { private:

Write a MAIN function and a FUNCTION which will print out the sum of each column of array A to the standard output. Within the MAIN function: . Initialize a two-dimensional 5X6 integer array A from the standart input. Pass the array A to the FUNCTION as an argument. Within the FUNCTION: . Read array A and compute and print out the sum of each column of array A to the standard output.

yes I'm aware I'm doing exactly that, because it wasn't what my focus was on so I didn't go in much detail about it

does anyone know octave apps

oh this is doing similar to what I already was doing, but I was doing something like void MEM::Reset(MEM &mem) { mem = *new MEM; }

oh this is doing similar to what I already was doing, but I was doing something like void MEM::Reset(MEM &mem) { mem = *new MEM; }

this probably might result in memory leak

oh this is doing similar to what I already was doing, but I was doing something like void MEM::Reset(MEM &mem) { mem = *new MEM; }

It will definitely leak

It will definitely leak

yes I knew it, thanks for confirming

oh this is doing similar to what I already was doing, but I was doing something like void MEM::Reset(MEM &mem) { mem = *new MEM; }

1) this does leak memory 2) i sent that to tell you that it's a terrible practice to call the constructor for re-initialisation

oh this is doing similar to what I already was doing, but I was doing something like void MEM::Reset(MEM &mem) { mem = *new MEM; }

mem = MEM();

Just return by value your pointer

I think your idea of calling Reset in constructor would be better choice;

Also void foo(Mem*& ptr_ref)

Also void foo(Mem*& ptr_ref)

I think this is not the desired logic

I mean from what I've read the task

I mean from what I've read the task

I'm too lazy to do it :P

mem = MEM();

that might still be dangerous because Reset() isn't static a.reset(a);

that might still be dangerous because Reset() isn't static a.reset(a);

it is static, not an issue

it is static, not an issue

oh

that might still be dangerous because Reset() isn't static a.reset(a);

I think it shouldn't be an issue in any case 🤔 This code just calls default constructor and assignment operator

So it doesn't depend on other data from the outside

Thanks guys , it's working perfectly fine now

ye you are right. *this would change, not this.

Using an array of size 5, we want to implement a queue using circular arrays. What will be the contents of the array after executing below operations? Why do we use circular array queue implementation? enqueue(1) enqueue(5) dequeue() enqueue(7) dequeue() enqueue(2) enqueue(4) dequeue() enqueue(6)

nah nothing, just saying hi

What is that even supposed to mean?

hhhhh thanks any way guys

Probably these guys are students who wants to do they homeworks. I don't think they want to learn coding, They just want the answer to pass the exam :) by grumbling we don't help them...

just use your reset and do std::fill(std::begin(memData), std::end(memData), 0); but you could just use std::array directly or write an alias with your custom MAX_MEM

I think this is the best solution, there is an alternative if you really want to have all the data initialized before the ctor body: MEM() : memData({4,5,6,7,8}) { } // assuming you have MAX_MEM == 5

Grades won’t help you if you get a job 😂
