#include<iostream> using namespace std; class Test { private: int x; public: Test(int x = 0) { this->x = x; } void change(Test *t) { this = t; } void print() { cout << "x = " << x << endl; } }; int main() { Test obj(5); Test *ptr = new Test (10); obj.change(ptr); obj.print(); return 0; }

What's problem with my code can anyone fix it ?

You can dereference this and t (*this=*t) and that will work #include<iostream> using namespace std; class Test { private: int x; public: Test(int x = 0) { this->x = x; } void change(Test* t) { *this = *t; } void print() { cout << "x = " << x << endl; } }; int main() { Test obj(5); Test* ptr = new Test(10); obj.change(ptr); obj.print(); return 0; }

A serial transmission line can transmit 960 characters a second. Write a program that will calculate how long it will take to send a file, given the file's size. Try it on a 400MB (419,430,400 byte) file. Use appropriate units. (A 400MB file takes days.) c++

Someone help me with this pls??

Guys, can you help with a piece of code in C: in general, 3 arrays and 2 array sizes are passed to the function. Array u with elements from (1 to 10 ) and a , with elements specified by the user (the main thing is that they are included in u), as well as their sizes , size u = 10 , and the size of a is respectively set by the user . So, you need to write elements in the form of 0 and 1 to the third array, 1 will be where the index of the array u during the cycle from 1 to 10 will match the value of the element that is in A, and in the remaining positions from 1 to 10 there will be 0

can anyone help with this pls Write a small program (can be just a main program without any functions) that reads the standard input and copies what it reads to the output so that is it a valid C string constant. In other words if it reads in the string EECS 2031 Linux and C it produces: "EECS2031\n\ Linux and C" In other words it replaces new lines with \n\ followed by a new line. It also replaces double quotes with backslash followed by double quotes. So, if it reads in the string EECS 2031 "Linux and C" it produces: "EECS 2031 \"Linux and C\""

Please answer me

Dear Mr. Developer, indeed in this group of over 16k members are present people who have the knowledge of C#. Hope that helps

If I write and use a program in the C # programming language, it will work on my computer But I compilation it to exe file does not work on other computers

I would appreciate if you would after trading and accepting the rules follow them. Most of members don't have problem with abiding them. Thanks

If I write and use a program in the C # programming language, it will work on my computer But I compilation it to exe file does not work on other computers

exe file only works for same architecture, you need to recompile for different kind of machine

how i am just starting to learn programming Please Help Meee !!

Lots to learn before asking

I've seen a lot of video tutorials about this but it doesn't help

And google.com

Google doesn’t always help like a living person, so I asked for help from the iss

What a rule

its normal if exe doesnt work on other computer, you need to make new exe file for new computer

It knows much better than a living person

its normal if exe doesnt work on other computer, you need to make new exe file for new computer

thank you answer i created a setup installation file that should work on other computers too

what error message do you get my friend?

Rupangel, our little princess, has just begun to learn how to count from zero to nine. All she wants to do at this point is counting everything. As a result, her teacher devises a strategy to motivate her. They are going to tell her the first number between 00 to 99 and she has to find the N_{th}N th ​ number of the sequence. The formula to find the next number of A is:- Count the frequency of all digits(DD) and write the frequency(FF) as F_0D_0 F_1D_1 ….. F_9D_9F 0 ​ D 0 ​ F 1 ​ D 1 ​ …..F 9 ​ D 9 ​ without spaces. Ignore F_iD_iF i ​ D i ​ if F_iF i ​ is 00. (i.e: 12231223 -> 112213112213). Assist Rupangel in determining the N_{th}N th ​ number in the sequence. Input The first line of the input is as an integer T(1 \le T \le 2000)T(1≤T≤2000) denoting the number of test cases. Then there will be T lines containing two integers N(0 \le N \le 9)N(0≤N≤9) and K (1 \le K \le 10^9)K(1 ≤ K ≤ 10 9 ). Here, NN will define the first number of the series, and KK will define the position of the number of the series. Output The output will be the number at K_{th}K th ​ position. Sample Input Output 3 1 1 2 1 3 2 Case 1: 1 Case 2: 2 Case 3: 13

Hello, I have a question. I know that the number of conversion specifiers must exactly match the number of input data. I'm just curious, it was stated that blank spaces are skipped when looking for an integer. int x; scanf("%d", &x); printf("%d", x); input: 3 5 output: 3 expected output: 35 Why is that? I learned that when looking for an integer, it will skip whitespace characters if needed. Furthermore, when an item is matched correctly, the scanning will continue until it matches an item that cannot possibly belong to the item, right? So it will skip the blank spaces after the 3, and it will read 5, yet 5 can belong to x since it is an integer value. I'm just curious about scanf, and I want to learn more about it. I know that if I am going to input two integers, I must add another conversion specifier in the format string. Thanks!

Wow interesting, this makes me have a question When obj's destructor called, mean obj's lifetime has ended, and we delete ptr, does that result in double free?

hi, could someone help me with a program?

Union and struct are very similar except the way memory location is stored. So far I have only use struct. Is there a situation where union is preferred or better? Anyone has any experience to share?
