QUESTION
So basically I am getting two string inputs in the form of coordinates as (x,y) and then I am adding the numbers from the inputted string (which are p1 and p2) to different variables and then adding those variables (which are x1,x2,y1,y2). So is there a way to add the variables together i.e perform arithmetic on the variables, (not concatenate)
...ANSWER
Answered 2021-Jun-15 at 13:14You can do this with std::stoi()
. Add a line to put these string
s into int
variables and do your arithmetic:
int x = stoi(x1);
QUESTION
I was trying to do a hangman game, my idea was that you give the number of letters and the word, then the program fills a char with _
as letters the word has. Then it asks you a letter and it compares if the letter matches any letter in the word given. Then it replaces the respective _
with the letter, but it doesn't replace it...
What am I doing wrong?

char blank[n - 1];

I am solving this homework problem: Find a pair of adjacent words in the text, such that both words begin in the same letter.
I understand that I need to use strtok
function to solve this problem.

starts printing from the second word because you never print the first token, i.e. the one you've obtained from the initial call tostrtok_s
before entering the loop.- Token is a regular C string. Its initial letter is
token[0]
, achar
. You can store it in a separatechar
variable, and carry it over into the next iteration of the loop. - Since the words could be in mixed case, you should probably use
toupper
ortolower
when storing and comparing the initial characters.

QUESTION
Mostly all things explained by fredoverflow(user 237K Rep.) in his Two answers
But while implementing Move constructor and overloaded Move Assignment operator(OMAO
)( I am using these short form throughout the question ) I am facing some problem that I will put here.
Also there is another answer by user Greg Hewgill (user with 826K Rep.)
https://stackoverflow.com/a/3106136/11862989his
I am Quoting him,
Suppose you have a function that returns a substantial object then an ordinary C++ compiler will create a temporary object for the result of multiply(), call the copy constructor to initialize r, and then destruct the temporary return value. Move semantics in C++0x allow the "move constructor" to be called to initialize r by copying its contents, and then discard the temporary value without having to destruct it.
I will also refer this in question.
okay Now I will start
Code .cpp ...ANSWER
Answered 2021-Jun-03 at 03:541_main: Move constructor is not executed due to copy elision The extra destructor is observed after the swap is done, the temporary object is destroyed.
2_main: Same observation as in 1_main where move operator is called
3_main: The error is seen because you're using a low version of compiler. might need to specify -std=c++11
4: a.s=nullptr
is not a case of move as you're allocating new memories and do kind of copy. For example

In the example below, I created a linked list and I can add numbers successfully. However, at the end of the execution, the function named "traverse" does not work. How can I fix this error?
Here is my code:
...ANSWER
Answered 2021-Jun-03 at 07:21If you have decided on C, then continuing from the comments, you are attempting to update a local copy of the pointer head
in add()
. As mentioned, you have two option, either change the return type of add()
to node *add()
so you can return ptr
and assign as the new head
back in main()
, or pass the address of head
as the first parameter and update the node stored at the original pointer address in add()
.
You can pass the address of head
to add()
as follows:

I am programming a simple text editor in C and I defined a structure named node and created a linked list named textbuffer. I am trying to create an insert function for the text editor. Here is the code so far:
...ANSWER
Answered 2021-May-27 at 19:24You can do all kinds of cursor manipulation and many more screen manipulation (insert, delete, clear, select color and more) using escape sequences. This can be done under Linux using the ncurses library which does it almost whatever the terminal is. But today, most if not all terminals are supporting XTerm escape sequences which inherit from ANSI, VT100 and VT52. This also works in Windows 10. Have a look at this Wikipedia article for more information.

QUESTION
My task is to find the minimum number between n input values that the user should enter in an infinite loop until a certain number or character is entered to stop the loop.
The problem that I am facing is, I can't get the condition that tests the input to see which of the entered numbers is the smallest to work. Also, a second problem is, I want to end the loop with a char not an int, but I don't know if that is even possible.
I searched online but I can't find any answers.
Side note: I am new to C++. I am using Borland C++ v5.02.
...ANSWER
Answered 2021-May-17 at 01:37I solved your problem by using a try-catch block and stoi().
stoi()
is used to convert a string into a number. If the number input is not convertible (meaning that a char
is entered and the loop should break), const std::invalid_argument & e
is catch and automatically break the loop.
