So I have the following code: char v[3] = { ‘a’, ‘b’, ‘c’ }; cout << v; cout << v[3]; The array only has 3 elements, yet when I display v it shows a few more characters after, and when I display v[3] it shows a character instead of throwing an error. What is going ..

I want the user to decide the array length by using cin. I have tried changing the scope but as expected it doesn’t work. I would be grateful if you suggest me some changes in the code or the approach. Thank you. #include <iostream> using namespace std; //declaring functions void choose(); void add(); void average(); ..
so i am making a program that takes student data as objects and prints it, i am trying to store the data as an array so each student is a element in the array, i am having issues with printing the data though as i cannot pass the array into the print function, can anyone ..
So the server sends the data just as packed structures, so what only need to decode is to overlay the structure pointer on the buffer. However one of the structure is a dynamic array kind of data, but I learned that flexible array member is not a C++ standard feature. How can I do it ..
I am trying to run a bubble sort algorithm which sorts an array in an ascending order but it comes out with segmentation fault in the online compiler and I can’t figure out what’s going wrong in there because I think that an element in an array should have a size of four, but after ..
Im working on implementing sort algorithms for class and mergesort is the only one that has stumped me. Ive run into seg faults and other issues but once I’ve "solved" those im now stuck with the array giving duplicate values, memory addresses, and not sorted. Code below: void merge(int* array, int first, int mid, int ..
I would like to know what knowledge I lack about inputs of arrays. I want to input one character and then automatically go to the next line of the code. Here is the code: char word[21]; for(int i = 0;i < 21; i++) { word[i] = getch(); //cin>>word[i]; if(word[i] == ‘/’)break; } for(int j = ..
So I was watching a "Implementing array as an ADT" video and the person was using C and I’m using C++ so I had to change a little bit of my code. The Code: #include <iostream> class arr{ public: arr(int tSize, int uSize){ total_size = tSize; used_size = uSize; *ptr = new int(tSize); } int ..
I’m trying ton convert the following code from c++ to java and as I’m a beginner student in Java I have errors when tryin to assign the char to tabtemp. I didnt found examples with multiple For loops #include <iostream> #include <string> #include <vector> using namespace std; int main() { for (char a = 97; ..
When I first learned C++, I avoided STL because the project I was contributing to didn’t use it all (still don’t know why). Here’s how we did things instead. First, we have a memory class which houses a template function, which looks like this: /* ———————————————————————- create a 1d array ————————————————————————- */ template <typename TYPE> ..
